Cool Campus! A How-To Guide for College and University Climate Action Planning

Welcome to AASHE's first foray into the world of wikis! For those unfamiliar with the term, a "wiki" is an online collaboration tool that allows multiple users to directly edit one or more webpages through their web browser.

Because the field of campus climate planning is quite young and best practices are changing quickly, we wanted to release this how-to guide in a format that could easily grow and change over time. A wiki seemed like an great tool to make this happen. Our hope is that this interactive format will foster collaboration and build community among people developing campus climate action plans. For those who prefer a more conventional format, a printer-friendly book version of the guide (pdf) is also available.

We invite and encourage you to help us keep the guide current and relevant by contributing to the wiki. You can edit any page in the wiki by clicking the "Edit page" link at the bottom. Alternatively, if you are logged in, you can also click the "Edit" tab at the top of the page. For additional guidance on using the wiki, please see the instructions.

We are greatly indebted to Walter Simpson, CEM and LEED AP, for providing the original seed text for this wiki, which was officially launched in April 2009. Walter is a retired Energy Officer from University at Buffalo and the former Director of UB Green. We are also grateful to the following reviewers for the constructive criticism, guidance, and suggestions they provided after reviewing a draft of the guide:

1. Introduction

1.1 Defining Campus Climate Action

Concern about global climate change has existed on college and university campuses for decades. However, it is only within the last few years that institutions of higher education have recognized this problem en masse and have begun making institutional commitments to addressing this threat. Often the call for collective campus-wide action has come from students and faculty but occasionally it has emanated from facilities or other professional staff or from the highest levels of campus leadership.

Initially, schools were largely on their own in efforts to address climate change. While some regional and national organizations provided support services to campuses that chose to address climate change, it was entirely up to each campus to develop its own goals, program, process, and resources – and to proceed to implement curricular changes and operational greenhouse gas emissions reductions on its own. This changed dramatically in the autumn of 2006 when the American College & University Presidents Climate Commitment (ACUPCC) was founded. Since then over 600 colleges and universities have signed the Commitment.

The ACUPCC represents one form of campus climate action. But it is not the only one. For a variety of reasons other colleges and universities have developed their own campus climate action programs with different goals and expectations. All these schools have this in common: a recognition of the over-riding problem of global climate change and a commitment to exercise leadership in responding to it – through curriculum, research and campus operations.

About the ACUPCC
The American College & University President’s Climate Commitment is a network of institutions led by a steering committee of college and university presidents and chancellors, and supported by three non-profit organizations:

Participating institutions have agreed to incorporate climate change and sustainability into the educational experience of all students and to achieve climate neutrality at the earliest possible date.

For the purposes of the ACUPCC, climate neutrality is defined “as having no net greenhouse gas (GHG) emissions, to be achieved by minimizing GHG emissions as much as possible, and using carbon offsets or other measures to mitigate the remaining emissions.” ACUPCC participants have agreed to develop plans for eventually achieving campus climate neutrality to:

  • Convey the magnitude of the societal challenge we face, i.e. the world’s top scientists say that by 2050 we need to reduce GHG emissions by at least 80%
  • Demonstrate leadership and inspire others to act in dramatic ways
  • Encourage quick, significant greenhouse gas emissions reductions now
  • Galvanize transformation changes on behalf of sustainability
  • Create a comprehensive vision of campus sustainability including Education and Research, Operations, and Administration and Finance.

ACUPCC institutions have agreed to complete a climate action plan within two years of signing the ACUPCC.

Throughout this guide, information of special relevance to ACUPCC signatories is highlighted with the ACUPCC logo (like at the beginning of this section).

More information about the ACUPCC is available on its website.

1.2 What Is a Climate Action Plan and Why Do One?

There are a variety of real-world reasons why campus leaders make commitments to academic and operational programs to address climate change. These include:

Of course, making a commitment and keeping it are two different things. On many campuses there are undoubtedly students, faculty and staff wondering “how do we get there from here?”. That’s where a campus climate action plan comes in.

Ad hoc actions can take you in the right direction but a plan can provide:

A campus climate action plan can be a roadmap to get your school to the promised land of climate protection. Important components include:

In all likelihood your climate action plan (CAP) will contain more than these items since it is one thing to list planned actions and quite another to include all the details needed to facilitate actual implementation. Practical considerations such as financing will have to be incorporated. The proper sequencing and combining of actions is important, not only so momentum is created but also so your plan can take advantage of synergies and allow early steps to set the stage for later ones. Since the success of your plan requires on-going effort by so many different individuals, offices, and constituencies on and off campus, you may find that the process used to develop the plan is as important as the final plan itself.

1.3 About this Guide

While there are a number of excellent campus climate planning resources available, this guide attempts to fill a gap by providing an abundance of “how-to” information. The goal of the guide is to assist climate action planning teams at schools that are well versed in campus climate issues and well along in the CAP process as well as those who are just beginning in this endeavor -- and may be wondering where to start and what to do. This guide deliberately errs on the side of providing a lot of detail to maximize its potential helpfulness. Apologies if there is too much detail!

While planning steps are presented in a logical sequence, you may find that proceeding in a different order makes sense for your school or that working on a number of these items simultaneously will be most effective. You can also use this guide as a reference book and just consult topics of interest.

1.4 Where to Find Campus Examples of CAP-Related Projects

All of the topics covered in this guide would make more sense if illustrated by real-life examples of campus projects and initiatives. However, to keep the length of the guide somewhat manageable, campus examples are generally provided at the end of each section via reference to appropriate webpages on the AASHE and ACUPCC websites. In the event that campus examples for particular topics are not provided on these sites (or if there are other websites with good campus examples), those other links are also provided.

Also, please see the “Campus Climate Action Planning Resources” chapter, which lists and provides links for a number of excellent CAP resources – organizations, publications, and web-based information. An especially good resource which describes seven campus climate action plans is the National Wildlife Federation Campus Ecology publication, Guide to Climate Action Planning: Pathways to a Low Carbon Campus.

AASHE’s Resource Center is the most complete and extensive green campus web resource of its kind. Note that some portions of this resource center are "members only" resources which require logging in to use. If your institution is not an AASHE member, you can learn more about it on AASHE's membership pages.

For sample campus climate plans, see: the Climate section of the AASHE Resource Center and the "Overview and Examples of Climate Action Plans" section of the ACUPCC website.

2. Creating an Institutional Structure for Your Climate Action Plan

A first CAP planning step is creating appropriate institutional structures for preparing and implementing your plan. Typically, this means identifying participants and establishing one or more committees or working groups – necessarily working with the full blessing, support, and involvement of top campus leadership. As you develop your CAP team, be sure to focus on existing institutional strengths and attempt to bring into the fold those who have already been working in this field, academically or operationally.

Top-level support from the president or chancellor is critical for success, as they are in the position to convene all of the various constituencies from the campus community that will need to be represented in the process.  Ongoing active involvement from the president or chancellor is also important in maintaining momentum and effectiveness.  To that end, the members of the ACUPCC Steering Committee developed Leading Profound Change - a peer-to-peer resource to support all presidents and chancellors in taking an active a leadership role in the ongoing process of developing and implementing the climate action plan. It provides an overview of research on select approaches to leading transformational change and examples of successful strategies from ACUPCC campuses to help with the big-picture thinking needed to sustain enthusiasm and implement climate action plans over the long-term.

2.1 Your CAP Team and Leadership

If your school already has sustainability staff or an energy officer or manager, these are key players and should be involved in leadership roles. Your campus environmental task force or sustainability committee also should play a central role. This committee may not have all the right people, expertise, or organizational capacity to undertake full supervision of the development of your CAP but it should be substantially involved in the process. There is everything to gain by including already identified campus environmental leaders, advocates, and enthusiasts on your CAP team.

Who are the people, offices, and constituencies that should be included in some way? Here is possible list:

Since our ultimate goal is to save the planet from the ravages of climate change, it is important to go beyond the confines of the ivory tower, get off campus, and include the wider community. Thus, your CAP team might include one or more liaisons with local government. Such an arrangement might inspire your county or local towns and cities to develop their own climate action plans. Similarly, if other schools in your area are committed to making significant reductions in GHG emissions, it could be mutually beneficial to include liaisons from each campus on CAP committees.

But who will lead the CAP effort? The leader or chair could be your sustainability director, if he or she has enough experience and the right credentials, or a prestigious faculty member who is given release time to take on this project. It could be a special assistant to your school’s president. Conceivably it could also be a very exceptional student who hopefully would be given substantial academic credit for taking this project on. An undertaking this large could have co-chairs. Whoever is selected to lead should be enthusiastically committed to climate action, have strong technical background in relevant areas, be engaging, fair, well-liked, and be able to motivate others and build a strong team.

The leader must be a collaborator at heart and encourage collaboration among all CAP team members and other members of the campus community. He or she must recognize key contributions while making all CAP team members feel as though the time spent on this project is time well spent – especially since many will be serving as “volunteers.” The leader must be on good relations with your president, have a direct line to him or her, and be able to bridge the gap or perhaps “the great divide” that may exist between campus leadership and campus grassroots. In the end, this is a people process and personalities make a huge difference. The right or wrong person or persons leading the CAP process can make world of difference.

2.2 CAP Committee Structure

Developing a CAP is a complicated and multi-faceted undertaking. While it’s a good idea to invite all interested and relevant parties to the table, they probably will not all fit around the same table! That means creating sub-committees or working groups. Here is a possible CAP organizational structure:

While all of the sub-committees have important assignments, the energy committee in particular has some heavy lifting to do. To accomplish its task, it might make sense for that sub-committee to create and manage individual working groups for each area --energy conservation, on-site renewables, green power purchasing, new construction/green design, CFCs, carbon offsets, etc. The energy sub-committee may be heavily comprised of facilities staff members who are responsible for campus energy systems and have expertise in the areas of concern.

Most campuses already have a proliferation of committees and meetings – so there is something to be said for economizing on the creation of new committees. Maybe existing committees can be assigned responsibility for some of the CAP tasks. Whatever structure you create, it should be a good fit to the way your school does business.

2.3 Transparency and Stakeholder Participation

Colleges and universities are intellectual communities whose members appreciate openness and enjoy vigorous public debate. Your CAP team should reinforce these desirable inclinations by maintaining a fully transparent process with lots of public or stakeholder participation and discussion. There are a variety of ways of doing this. Meetings of the steering committee and sub-committees can be advertised as “open meetings” so interested parties can sit in. Periodic reports and updates can be issued and publicized. Occasional presentations, workshops, and town meetings plus a regularly updated CAP website will keep the campus community informed and on-board.

2.4 Getting Started

As one of its first acts, the CAP Steering Committee – with full involvement from sub-committee members – could conduct a kick-off workshop, “charrette,” or even a day-long retreat to:

The vision exercise is a facilitated brainstorming session that asks CAP participants to imagine and create a vision of their institution as a genuine leader in addressing climate change, an institution that is:

The results of this exercise can be captured in a vision statement. This exercise is essential because the CAP process requires departing from past practice and “business as usual” and thus imagining a different future.

A SWOT analysis identifies institutional Strengths, Weaknesses, Opportunities, and Threats that will help or hinder the CAP planning process and eventual achievement of CAP goals.

It’s important that the CAP process be viewed as meaningful and effective public service as well as an enjoyable experience. The kick-off workshop should set the right tone. It’s important that your school’s president start it off with a brief statement and a hearty thanks to all participants.

2.5 Energizing the CAP Process

Here are some ways to energize your CAP team and its work:
**
1. Make sure you have an energized leader who is genuinely passionate about addressing the climate problem**. This person needs to be inspiring and bring an abundance of positive energy, enthusiasm, and good personal relations to all aspects of your work.

2. Be inclusive and invite onto your CAP team those who care the most about climate change and who bring the most positive energy to the work. Behind this point is a simple truth: energized people energize others! So open the door and invite these spark plugs onto your team.

**3. Regularly remind your CAP team how important their work is by reviewing the critical nature and urgency of climate change while at the same time sharing positive developments. **This is all about merging “gloom and doom” with hope! Both can motivate – though neither by itself is very effective. Guest speakers or faculty lectures on climate change can underline the importance of your work. Perhaps start each CAP meeting with a different committee member sharing two news stories, one about the latest scientific findings (generally bad news) and one about efforts underway to constructively address the climate problem (good news). To stay up-to-date with the latest news on climate change, consider signing up for the weekly newsfeed “Earth Equity News” from the Climate Crisis Coalition – founded by “climate crisis crusader” Ross Gelbspan among others.

4. Explore the emotional side of the climate change issue. While your CAP meetings may need to be business-like, it’s important to find opportunities and venues where team members as well as others on campus can get in touch with their emotions about climate change. The reality is that most of us, even environmental activists, are in deep psychological denial about this threat. To some extent, denial or psychic numbing is a necessary coping mechanism. But denial is also a danger since it diminishes our perception of the problem and excuses a lack of effort or urgency in addressing it. Of course, helping people get in touch with their emotions is risky because it could be a painful experience and send them running for the hills! It’s important to help people understand that they hurt when they contemplate the danger of climate change because they care so much about their families, society, future generations and the Earth. That understanding can produce deep positive motivation to continue this important work.

5. Ask your president to regularly demonstrate interest and support. Regular visits by your campus president to see how your CAP work is progressing will do wonders to keep spirits and enthusiasm high. Providing the resources you need is also critical to CAP energy levels. It might make sense to schedule an informal get together with your president, say every six months, to share with him or her progress and problems-to-date and thus to invite his/her continued involvement, encouragement and support. Keeping your president personally engaged will help your CAP team stay personally engaged.  The Leading Profound Change document from the ACUPCC Steering Committee underscores the importance of this sort of involvement and on a peer-to-peer basis it offers some practical approaches presidents can take. 

6. Develop a strategy to regularly celebrate small victories (as well as occasional large ones). Climate action is a huge undertaking and probably will take many years to achieve. To keep your climate action program stoked up during this period, you want to celebrate many smaller victories and achievements along the way. These small victories and your celebrations of them are so important that it makes sense to be very conscious and deliberate in identifying them within your CAP and making plans ahead of time to announce and celebrate them. These celebrations are great occasions for bringing your entire extended CAP team together, inviting campus leadership to say a few words, and praising/rewarding those who did the most to make the accomplishment you are celebrating happen.

**7. Have fun. **Let’s face it: so much of what we do on campus wears us down, especially when campus politics intervene. Contemplating the fate of the Earth is also a difficult assignment. So finding ways to have fun as you undertake campus climate action is very important.

2.6 CAP Communications

Reducing GHG emissions is a multi-faceted challenge. There are very strong awareness and behavioral change components. Thus, a communication strategy is key. That strategy should not only inform people about and invite them into the CAP process but it should encourage and facilitate their involvement as change agents, implementing carbon reductions and the CAP itself.

To be most effective, a communications strategy should tailor its message and media to different audiences on campus. Different strokes for different folks. At least these four steps are involved:

Given the importance of communications to reducing carbon emissions on campus, it makes sense to involve faculty and professional staff experts in communications, public relations, art, design, and media.

There are better and worse ways of communicating with and motivating people. For some great ideas, see Fostering Sustainable Behaviour: an Introduction to Community-based Social Marketing (Doug McKenzie-Mohr and William Smith, 1999) and The Low Carbon Diet: A 30 Day Program to Lose 5000 Pounds (David Gershon, 2006). The latter resource is often used in “global warming cafes” which use a highly effective methodology for motivating action on climate change.

2.7 Staffing and Resources Issues

But no matter how you look at it, addressing climate change in a serious way will increase workload. That’s reality. It needs to be addressed irrespective of whether the work takes place in new or existing campus organizations. While smaller schools may find the additional workload of the CAP process more manageable than larger schools, developing a plan and especially implementing it will be more work even if you hire a consultant.

This raises closely related issues of staffing and funding. Developing an effective CAP requires staffing, possibly new staff who will have the expertise and credentials for undertaking this work as well as have the time and means to make sure it gets done. Implementing it will also impose other staffing needs to motivate, coordinate, complete, and track needed projects and initiatives. Bolstering facilities staffing in the area of energy conservation is an obvious priority.

Adding staff and providing new resources during a time of economic stress is always difficult – though campus climate action advocates can argue that the climate program should be prioritized or at a minimum treated just like other campus programs that are adequately staffed and funded. In fact, on most campuses a great many programs are fully staffed that have far less significance – pedagogically and operationally – than campus efforts to responsibly address climate change. The extent to which your school provides the needed staffing and resources to develop and implement an aggressive and viable CAP is a true measure of top-level commitment. It will show in your final product and chances of success.

2.8 CAP Institutionalization

Success requires that climate action become an integral part of the way your college or university does business – day to day and over the long run. In other words, climate action needs to become institutionalized, part of “business as usual.” The challenge here is making sure that successful institutionalization doesn’t push climate action into the background. Your CAP and climate commitment need to be raised to a high profile and remain there.

Institutionalization of the climate initiative can be at least partially accomplished by incorporating the commitment in key documents that guide campus decision-making and planning, such as vision and mission statements, strategic and campus master plans, campus-wide policies, and annual “state of the institution” speeches by your president. But better than exploiting these modest opportunities is recognizing the unprecedented transformational potential of responding to climate change. For those who take this challenge seriously, addressing climate change can become a process for entirely rethinking our institutions of higher learning.

While there are a great many factors critically important for successful institutionalization of your CAP, at the very top of the list is continuous support and encouragement by your president and top campus leadership. They need to follow the planning process carefully, support and empower those who are developing the plan, be realistic about what will be required, provide needed resources and staffing, set an example in their own behavior and the operation of their offices and units, and use the bully pulpit of their offices to educate and motivate the campus community to step up and be part of the campus climate solution. Yes, that’s a tall order.

2.9 Some Guidelines for Hiring a CAP Consultant

Organizational capacity or expertise limitations may be overcome by selecting and hiring a consultant to assist campus participants develop a CAP. Even if your college or university is fully capable of developing a CAP on its own, it still may make sense to hire an expert consultant to increase the likelihood of developing the best possible plan in a timely fashion. Here are some possible criteria to use in selecting such a consultant to assist with the operations component of your CAP (reducing GHG emissions). While finding all of these attributes in one consultant might be difficult or impossible, ideally a consultant hired to complete or assist a climate action plan would:

In addition to the above, ACUPCC institutions should seek a consultant with thorough knowledge of the ACUPCC and who is able to explain the pros and cons of strategies which could lead to carbon neutrality.

3. Prioritizing Education, Research, and Public Engagement

3.1 Climate Change and Sustainability in the Curriculum

The world faces not only a climate change crisis but also threats to sustainability on all fronts. Thus, it is essential that colleges and universities formally acknowledge these transcendent problems and reorient academic programs to be relevant to the challenges all future graduates will face. Higher education has an obligation to lead in creating a healthy, just, and sustainable society.

It is essential that campus climate action plans address the curricular component of this problem by making climate change and sustainability a part of the curriculum and other educational experience for all students. Curriculum changes should involve all students given the critical nature of the climate and sustainability challenges we face and the urgent need for future professionals, leaders and citizens in all disciplines to be engaged and part of the solution to these problems.

To assist colleges and universities to do this, the ACUPCC is preparing Education for Climate Neutrality and Sustainability: Academic Guidance for ACUPCC Institutions (April 2009), a guide which can be used by all schools irrespective of their involvement with the ACUPCC. This chapter is draws heavily from the ACUPCC guide.

This guide recommends action and change in three areas:

Content of Learning – What do we want students to learn?
An excellent set of content recommendations for sustainability education was contained in the Essex Report, a 1995 document presented to President Bill Clinton’s Council on Sustainable Development. In that report, education leaders recommended teaching and learning experiences that enable students to understand:

To that list of educational outcomes can be added specific knowledge and understanding about global climate change:

The Context of Learning -- What are the avenues available to academics for educating students about sustainability?
There are a variety of opportunities to introduce and address sustainability and climate change in the academic context. Some of these opportunities are course and program-specific while others infuse eco-literacy across the curriculum and in other student learning opportunities. These opportunities include:

The Process of Education -- What are the pedagogical methods for teaching systems thinking and the interdisciplinary concepts of climate change and sustainability?
Possible pedagogical methods include:

A variety of strategies can be used to develop the capacity to launch and undertake these changes:

Here are some other specific ideas for greening academics:

For campus examples and more discussion, see the ACUPCC's Academics page and the Curriculum section of AASHE's Resource Center.

3.2 Climate Change and Sustainability Research

Another avenue for addressing climate change on campus is research. ACUPCC institutions agree to develop climate action plans that expand research and other activities that will address climate change. Other schools may want to expand research in this area as well.

Refocusing research on campus is a tall order since faculty research is driven by not only institutional priorities but also by the research interests of existing faculty (and they know their research interests and generally don’t take kindly to others telling them what they should be interested in) and the availability of research dollars. Fortunately, identifying new faculty with an interest in climate change-related research is probably going to get easier now that awareness of and concern about the climate change problem is becoming the norm in the U.S. Also, with the new Obama Administration it is clear that climate change is going to be dealt with seriously. Thus, even in the context of the current economic meltdown and unprecedented federal budget deficits, it is likely that much more money will be available for research in this critically important area.

Here are some possibilities for increasing on-campus research on climate change, drawn from the ACUPCC Implementation Guide and elsewhere:

For campus examples, see the Research section of AASHE's Resource Center.

3.3 Public Engagement on Climate Change

Here are some possibilities for increasing your school’s public engagement on climate change, as drawn from the ACUPCC Implementation Guide and elsewhere:

And don’t forget:

Conferences and meetings can be carbon-free by locating them convenient to public transit, maximizing the use of teleconferencing, reducing on-site energy use and carbon emitting behavior, and then purchasing carbon offsets for remaining GHG emissions. See TerraPass’ Event and Conference Carbon Footprint Calculator for an easy way to calculate these emissions.

Many sustainable event planning manuals are available on-line. For examples, see:

There are many such manuals though the latter one from Monash University in Australia is somewhat unique in encouraging vegetarian food. See the "Food Service and Food Choices" section for information on the significance of livestock production and diet in causing GHG emissions.

4. Determining Your Carbon Footprint and Emissions Trajectory

4.1 Conducting a Greenhouse Gas Emissions Inventory

While it is not necessary to conduct a campus GHG inventory to reduce GHG emissions, a GHG inventory is an essential step in assembling a CAP. ACUPCC participants agree to conduct a greenhouse gas (GHG) inventory within one year of signing and then to update that inventory at least every other year. This frequency for renewing a GHG inventory is appropriate for all campuses pursuing GHG reductions.

A GHG inventory will provide a general diagnosis and a measuring stick to determine success or failure in your efforts to reduce GHG emissions. The inventory does this by establishing and quantifying your campus’ carbon footprint in terms of metric tons of carbon dioxide equivalent per year (MTCO2e/yr). Metric units are used because of the international nature of GHG emissions accounting. GHG emissions are quantified in terms of “CO2e” or carbon dioxide equivalent. There are a number of greenhouse gases whose atmospheric concentrations are increasing as a result of human activity. These GHGs include carbon dioxide, methane, nitrous oxide, ozone, and chlorofluorocarbons. Carbon dioxide from burning fossil fuels and destroying forests is having the greatest impact on climate, and, consequently, emissions volumes for combinations of GHGs are generally given in terms of equivalent amounts of CO2.

An inventory is also an awareness raising tool. It allows green campus advocates to equate energy-wasting activities to the problem of climate change by showing their consequences in terms of GHG emissions. This can be a big wake up call. Making this connection can motivate behavior change.

The first time you calculate your annual GHG emissions it makes sense to do so not only for the most recent year for which you have data but also for a number of preceding years in order to reveal your GHG emissions trajectory. By comparing inventories of successive years, you can see additional trends which will help your analysis.

These steps are involved in conducting a GHG inventory:

GHG emissions scopes 1, 2, and 3 are defined by international protocols. Your campus climate commitment and CAP should specify which categories of GHG emissions you are committed to reducing and to what extent. In making a commitment to climate neutrality, ACUPCC participants have agreed to eventually fully mitigate the following categories of GHG emissions and thus should include them in their GHG inventories:

Many institutions choose to include emissions from other GHG sources in their inventories since counting and discussing them increases the likelihood that efforts will also be made to reduce them. These other sources of GHG emissions include waste disposal, embodied emissions in the products and services your college or university buys, outsourced activities, contractor owned vehicles, and even line losses associated with bringing electric power to your campus. Of the above, the most easy to calculate may be the GHG emissions associated with waste disposal since the Clean Air-Cool Planet “Campus Carbon Calculator” (see the "Clean Air-Cool Planet GHG Inventory Tool" section of this guide) is already set up to do this. The embodied energy in product purchasing is undoubtedly huge but can be quite difficult to calculate.

The GHG inventory tool is essentially a spreadsheet which will calculate your school’s carbon footprint once it has all required input data. The raw input data you will need generally falls into these categories:

Obtaining this data can be like conducting a scavenger hunt. You will need to identify campus sources of data and then arrange for them to provide it to you. The ACUPCC Greenhouse Gas Inventory Brief offers these excellent suggestions on gathering input data for your inventory:

For more information about conducting a GHG inventory, see the ACUPCC Implementation Guide and Clean Air-Cool Planet's Campus Climate Action Toolkit.

4.1.1 Data Collection and Calculation Method for Commuting and Air Travel

More so than for most other categories of GHG emissions, those associated with commuting and air travel tend to be based on assumptions. To make these assumptions, some raw data is needed but it tends to be indirect in nature. For guidance on data collection and calculations for these two categories of emissions, see "Guidance on Scope 3 Emissions: Commuting" by Niles Barnes and "Guidance on Scope 3 Emissions: Air Travel" by Julian Dautremont-Smith.

For commuting, your goal is to estimate the number of gallons of gasoline that is consumed by this activity. To do that you will need to estimate total miles driven and make an assumption about average fuel economy. A fair number to use for the latter is the U.S. average fuel economy for all cars and light trucks, estimated by the U.S. Environmental Protection Agency to be “an uninspiring 20.8 mpg”. Coming up with total miles driven is a bit harder. Some schools have required that all students, faculty and staff requesting a parking permit fill out a questionnaire to provide this data, i.e. round trip commute mileage, number of trips per week, etc. Other schools have used existing parking hang tag databases which contain home or campus address information and extrapolated from that – subtracting out the savings associated with those with parking passes who occasionally carpool, bike, take public transit or walk. Depending on your methodology for calculating the carbon footprint of commuting, it may or may not capture the emissions reductions that occur as a result of transportation strategies you implement to reduce driving and fuel use.

For air travel, your data collection goal is total passenger air miles paid for by or through your institution. Getting to this number may be difficult, depending on how travel information is collected and archived by your school. In addition to carbon dioxide emissions associated with burning jet fuel, the climate impact of air travel is a function of upper atmosphere emissions of nitrogen oxides and other factors. The Clean Air-Cool Planet Campus Carbon Calculator (discussed in the next section) incorporates a radiative forcing factor of 2.8 to account for this additional impact.

4.1.2 Data Collection for Campus Forest Offsets

Please see "A Recommendation on How to Account for Carbon Sinks in Campus Forests or Lands" by Jenn Andrews and the the "Campus Forest and Lands as Carbon Offsets?" section of this guide for a discussion of the tricky business of counting campus forest preservation as an offset to your campus carbon footprint.

4.2 Clean Air-Cool Planet GHG Inventory Tool

A number of GHG inventory tools are available. The ACUPCC participants agree to use one compliant with the Greenhouse Gas Protocol – a standard procedure for analyzing GHG emissions created by the World Resources Institute and the World Business Council for Sustainable Development.

Clean Air-Cool Planet’s “Campus Carbon Calculator” (available for free download) is compliant with this protocol and is the inventory tool most commonly used by campuses. Essentially, it is an elaborate Excel spreadsheet. You plug in the required data and it calculates total GHG emissions and the subsets of GHG emissions associated with various categories of input data.

The CA-CP Campus Carbon Calculator also makes analysis of your carbon footprint easy by providing a variety of ways of presenting, comparing, and trending the results. Each version of this excellent tool becomes more sophisticated and helpful. The Calculator will generate emissions trajectory graphs and allow you to normalize GHG emissions data in relation to various institutional statistics (see the the "Relative Measures of Progress" section of this manual for discussion of normalized GHG data).

Version 6 of the Campus Carbon Calculator has a solutions module with a number of interesting features. It will allow users to analyze and compare specific projects once project data is entered (see the "Carbon Reduction Efficacy" section of this manual for $/MTCO2e comparison of projects) -- thus ranking carbon-reducing projects according to their relative cost-effectiveness. This version can also calculate electricity line losses as well as production-related emissions for various grades of office paper. The latter may help you make the case for buying only 100% post-consumer content recycled paper. A future generation of the Calculator is expected to include a tool for calculating the carbon footprint and other environmental impacts associated with campus dining services.

4.3 Your Carbon Footprint and Trajectory – What to Expect

While your GHG emissions inventory can quantify your carbon footprint and its major elements, it may not produce any real “Ah-hah’s!” The major sources of your carbon footprint should already be obvious. Typically, they are:

Your own GHG emissions inventory will likely confirm this. Putting some numbers to it can help, especially for those who don’t believe something is real unless it can be quantified.

When multiple years are analyzed, a GHG emissions inventory will show if emissions are holding steady, rising or declining over time. After some analysis, you might conclude that a trajectory of decreasing emissions over time can be explained by a successful energy conservation program or that an upward emissions trajectory can be explained by new construction, additional students, or more research activity. If you anticipate future campus growth, you could extrapolate from your recent trajectory and show that anticipated growth as an upward-pointing baseline from which you hope to deviate downward as a result of campus GHG emissions reduction efforts. Generally, your carbon footprint and trajectory will track energy use.

Your GHG emissions inventory may show you in graphic terms that your emissions are inching up each year for no apparent reason! In energy terms, this is often called “load creep.” An unaccounted-for upward creep in energy use and GHG emissions might be due to increasing computerization of your campus or a great number of small unidentified developments that collectively add up to incrementally greater energy use and thus more GHG emissions.

Obviously, if your school’s GHG emissions are on an upward trajectory for whatever reason, reaching aggressive campus climate goals is likely to be more difficult. As you identify measures and projects that can produce annual GHG emissions reductions, your CAP will need to subtract those anticipated reductions from an upward trending line – yielding less net reduction of GHG emissions than would occur if your trajectory were flat or already downward.

A GHG emissions inventory is helpful but it is not a silver bullet. It won’t for example, tell you what emissions mitigation opportunities exist in various buildings. An energy analysis of those buildings is required for that.

4.4 Who Should Conduct Your Inventory?

Who should perform your GHG inventory? If you haven’t done a GHG inventory before, you might assume it is very complicated and that you need to hire a consultant to do it. But while it takes time, inventory tools like CA-CP’s carbon calculator make doing a GHG inventory relatively easy. You may find that the hardest part is just gathering the needed data from various campus offices and departments.

Thus, a GHG inventory can be done in-house. It could be assigned to an energy manager, facilities engineer, or a sustainability coordinator. Students and faculty could also be recruited to help conduct your GHG inventory. In that way the inventory becomes a broader learning experience. While conducting the inventory itself does not represent a full semester’s work, an academic course could be created around the inventory by asking students to also unpack and study the “guts” of the inventory tool (examining its assumptions, learning how the spreadsheet works, etc.), develop campus GHG emissions mitigation strategies, create a simple CAP, and study the problem of climate change generally.

When gathering data for your first inventory, it makes sense to set up systems with the parties involved so that the same data can be more easily collected in future years.

4.5 Rolling Out Your GHG Inventory

The completion of your GHG inventory presents an important opportunity to raise awareness about your school’s impact on climate change and about the CAP process you have begun. For this reason, it makes sense to roll out your inventory with as much fanfare as possible. Your CAP team can brainstorm the most effective ways of doing this. It will help if the inventory is incorporated into a report about the need to reduce campus GHG emissions with examples of what your school is already doing and might do in the future.

Some outreach possibilities for releasing the inventory include:

4.6 How Much GHG Number-Crunching Should You Do?

The increasing sophistication of GHG inventory tools comes at a price. After a point, more information and detail about your carbon footprint may not help you undertake the really important task of reducing those emissions. There are only so many hours in the day to do this important work and energy and sustainability staff are already stretched thin and over-worked. Thus, it is critically important not to get sidetracked over-analyzing your carbon emissions and, as a result, not have enough staff time to implement mitigation measures and projects. For example, should you refine your GHG inventory to the point where you know the carbon footprint of each campus building? Probably not unless you are sure that having those numbers will actually help you modify building energy systems and human behavior in campus buildings to produce additional energy and GHG savings worth more than the time and cost involved in completing that level of analysis.

When it comes to number-crunching, you need to be selective. What types of analysis will really advance your program? Consider what can be done with a handheld calculator. Suppose your campus’ carbon footprint was 100,000 MTCO2e/yr and you have 20,000 students. Simple arithmetic tells you that on a per student basis your school’s emissions are 5 tons of CO2 per year. Since burning a pound of coal releases 3.667 pounds of CO2, the average student is “responsible” for campus GHG emissions equal to burning 2,727 pounds of coal! Your CAP team could create a great motivational visual by dumping that much coal in front of the student union to dramatize each student’s impact.

4.7 How Geography or Your Power Provider Can Affect Your Carbon Footprint

Campus GHG inventories reveal that the geographical location of your school can make a big difference. Consider a college or university in a region of the country where most of the electricity is generated by burning coal. Each kilowatt hour of purchased electricity from that coal-intensive electric grid “contains” or is responsible for a much greater release of carbon dioxide than a kilowatt hour purchased by a school that receives power from a grid dominated by “lower carbon” natural gas generation or “zero carbon” hydro-electric or nuclear power. These regional differences in GHG emissions-intensity are captured by GHG inventory tools because they use CO2/kWh conversion factors based on the mix of electricity generation methods which exist in each region of the country.

It could be argued that colleges and universities in coal states like Ohio shouldn’t be “penalized” and forced to deal with much larger carbon footprints simply because they are in a part of the country where power is mostly generated by coal. However, this approach is reasonable and fair because there are real differences in the climate change impact of buying and consuming electricity in different parts of the country. Campuses in states with carbon intensive electricity generation will likely want to prioritize conserving grid-sourced electricity since each kilowatt hour they save will yield disproportionate carbon reductions.

A similar phenomenon can occur in electric markets where colleges and universities can buy power from private third party power producers (and use their local electric utility’s distribution system to deliver the power). The graph immediately below from the UC Berkeley shows what happened when in 1998 the university began buying its electricity from Arizona Public Services (APS). That moved caused the GHG emissions from UC Berkeley’s purchased electricity to more than double because of APS’ 38% reliance on coal. In 2006 Berkeley’s GHG emissions from purchased electricity dropped precipitously when the university resumed purchasing its electricity from Pacific Gas & Electric whose generation mix is 1% coal, 42% natural gas, 12% nuclear, 20% hydro, and 12% renewable.

5. Greenhouse Gas Mitigation Strategies

There are a great many ways to reduce GHG emissions on campus. This section of the CAP Guide presents basic GHG mitigation strategies and specific tactics/actions within these categories:

Moderator:

5.1 Energy Conservation and Efficiency

Burning fossil fuels -- and the subsequent release of carbon dioxide -- is the primary cause of global warming and climate change. Burning fossil fuels, including burning them to generate purchased electricity, is also the primary source of GHG emissions at colleges and universities. It follows, then, that the first and foremost campus GHG emissions mitigation strategy is energy conservation and energy efficiency improvements to reduce the use of fossil fuels.

5.1.1 The Power of End-Use Energy Conservation

**Nothing is cleaner than the BTU or kilowatt hour of energy that you don’t need, don’t consume, and therefore that doesn’t need to be produced or generated. **

Energy production and consumption have social and environmental impacts. Energy conservation avoids these impacts. Prevention is better than a cure.

End-use energy conservation has great power because units of energy saved at the point of use can save many times that amount of energy when the inefficiencies of energy production and distribution are taken into account. As this illustration below (redrawn from an illustration from Rocky Mountain Institute) shows, turning off a pump that produces work equal to 9.5 units of energy saves 100 units of input energy at the power plant -- and it saves even more energy than that if we consider the energy it takes to produce and deliver fuel to that power plant.

Suppose we need that pump to run but not at full speed. If we reduce the flow/speed of the pump by only 21%, the work the pump does decreases by 50% (i.e. 4.75 units of work energy output). This slight reduction can save 50 units of energy at the power plant! Since the pump in this illustration is running on electricity generated by burning coal, this example of end use conservation produces substantial reductions in carbon dioxide emissions – thus helping to put the brakes on climate change. Imagine the impact of turning off or turning down all those pumps, fans, lights, and other energy-using appliances on campus that don’t need to be on right now. Energy savings of this magnitude are wildly exciting to contemplate!

5.1.2 Energy Conservation Program Elements

Here are key components of an effective campus energy conservation program to reduce energy use and GHG emissions from campus operations:

  • Strong Program Leadership

    • An energy officer to develop energy conservation measures and projects and catalyze the entire effort
    • Full support from facilities leadership, the chief business officer, and the president
  • Enhanced Energy Awareness (see detail in the "Energy Awareness" section)

  • Aggressive Energy Conservation Policies which address:

    • Heating and cooling season temperature settings
    • Building HVAC and fan operating schedules
    • Computer operations and "green computing"
    • Ban on all incandescent bulbs and halogen torchiere lamps (the latter is also a safety issue)
    • Energy purchasing (including buying green power)
    • Energy efficiency purchasing standards for various types of equipment -- hopefully going beyond Energy Star compliance
    • Improved space utilization to avoid new construction or heating/cooling of underused space
    • Energy efficiency standards for new construction
    • Restrictions on the use of portable space heaters
    • Energy practices in on-campus residence halls and student apartments
    • Residential appliance policies (e.g. load limits per room, ban refrigerators, TVs, microwaves, etc.)
    • Curtailment periods when campus use is minimal and energy shutdowns can be implemented
  • Engaged Facilities Operations

    • An active facilities energy conservation committee which meets regularly and is encouraged and empowered by the physical plant director (and campus leadership) to push the envelope and aggressively pursue all conservation opportunities
    • Comprehensive implementation of no cost/low cost operational measures – e.g. temperature set-points, equipment run-times and building occupancy hours, etc. -- that push the envelope, i.e. risk complaints
    • Adequate facilities staffing levels – especially HVAC controls technicians, heating and power plant operators, mechanics, and electricians -- to operate the campus efficiently and readily implement energy conservation measures and projects in-house
    • Periodic re-commissioning of all existing buildings to optimize energy efficiency
    • Facilities staff performance appraisals that evaluate staff on commitment to energy conservation
    • Empowerment of highly motivated staff who are anxious to implement energy conservation measures
    • Rewarding of staff who identify conservation opportunities and implement conservation measures
    • Reconsideration of the timing of the academic calendar to better align it with periods of least energy cost operation, e.g. in cold regions this might involve shifting academic activity and campus occupancy away from the coldest months and implementing a partial campus shutdown during that period
  • Energy Smart Capital Improvement Program

    • Tough energy efficiency standards for all renovations and capital improvement programs
    • Prioritization of projects which conserve energy and improve efficiency
  • Deliberate Targeting of Worst Offenders

    • Specific, aggressive, comprehensive targeting of the most energy intensive and energy wasteful buildings and energy systems, e.g.:
      • Electric heating
      • Large outside air ventilation systems (e.g. in lab buildings)
      • Fan systems which operate at full capacity when actual occupancy is mostly a lot less
      • Heating and power plants
      • Super-computers
  • Energy Performance Contracting

    • Maximizing the scope, effectiveness, and benefits of performance contracting, i.e. large comprehensive, self-financed projects involving energy service companies (ESCOs). (See detail in the "Performance Contracting" section)
  • Green Computing

    • Purchase of ENERGY STAR computers and monitors.
    • Requirement that computers have power management features engaged and are shut off when offices are closed. US EPA ENERGY STAR offers free software and technical assistance to help universities activate power management features across a network - see www.energystar.gov/lowcarbonit.
    • Operation of computer labs to match operating computers to customer load
    • Full cooperation of campus IT departments in the design and operation of networked and campus-wide computer systems
    • Highest standards of efficient design for super-computers
  • Incentives for Energy Conservation

    • Innovative strategies to assign energy costs to campus energy users or cost centers to provide real dollar incentives for energy conservation for campus building occupants
    • Elimination of “split incentives” that discourage full cooperation with the energy conservation program
    • In multi-school college and university systems, a policy which allows all or part of the energy conservation dollar savings to remain with the school that achieved them
  • Super Energy Efficient Planning and Green Design for New Construction

    • Avoid new construction or only build the most energy efficient buildings to eliminate or minimize future energy conservation retrofitting
  • Documentation of Savings

    • Keep a log to document conservation projects and savings
    • Publicize, publicize, publicize!

For campus energy conservation program examples, see the Energy section of AASHE's resource center. This webpage includes links to numerous campus energy websites, energy plans and energy policies.

5.1.3 Energy Awareness

It is essential that everyone on campus pitch in. This can be accomplished by an effective energy awareness program or campaign that encourages individual and group action. Here are some energy awareness program considerations and ideas:

  • You are striving for culture change – a real shift in the way members of the campus community think about energy and their role in and responsibility for saving energy on campus
  • You are competing against a lot of other interests and activities on campus so you need to be both creative and persistent in getting the message out
  • Use environmental themes to motivate -- especially climate change; explain that:
    • Climate change is real
    • Its happening right now and faster than we previously thought
    • The consequences will be dire if we do not act
    • Let’s act now before it’s too late!
  • Take into account that not everyone on campus can do a lot to save energy – so target various constituencies with appropriate messages and aggressively target those who can do the most, namely:
    • Facilities management
    • Resident students
    • Building managers
    • Computer lab operators
    • Top leadership
  • Develop a multi-faceted campaign using as many media as possible
    • Campus actions and events
    • Newspaper articles and columns
    • Classroom presentations (target large classes)
    • Websites
    • E-mail blasts
    • Creative signage
    • Contests and competitions
    • Facebook groups, instant messaging
    • Mascots
    • Crazy stunts
    • Etc. Etc. Etc.
  • Make sure your facilities department is not overheating or overcooling buildings or allowing outdoor light fixtures to burn during the day, etc. because no one will pay attention to your energy conservation appeals if they see visible instances of energy waste on campus and don’t think facilities is doing its job
  • Be sure that you have vigorous recycling and other environmental programs because green programs reinforce each other, and the campus community is much more likely to participate in energy conservation if they can also easily recycle, use 100% post consumer recycled paper, bicycle to campus, sit on pesticide free grounds, go for a hike in preserved green space, etc.
  • Expand your awareness program through a building “conservation contacts network” with an environmental liaison in every office or department or an eco-reps program for on-campus residence halls and apartments
  • Encourage conserving behavior at home as well as on campus since these behaviors will reinforce each other

How much can you accomplish via awareness raising? A great deal if it gets facilities staff to use the tools at their disposal to save energy. An awful lot if you inspire your school’s president to set an example and let others know he/she expects others to follow his/her lead.

But what about the general campus population? An effective energy awareness program might reduce energy consumption on campus by 5 or 10 % or more. A great student research project would be to take one or more buildings, launch an energy awareness campaign and measure energy use before and after, and determine from that experiment how to do energy awareness raising with maximum success and how much energy saving is possible with various methods.

AASHE maintains an extensive list of campus energy websites.

5.1.4 Energy Conservation Measures

Standard techniques for conserving energy and improving energy efficiency in commercial or institutional buildings are well known to the vast majority of campus facilities managers. These strategies can be found in many places including in publications available through:

Or on websites such as these maintained by the U.S. Department of Energy:

Here is a list of some of some energy conservation measures that can be used in campus buildings:

  • Building envelope improvement
    • Weather/infiltration sealing
    • Increased insulation
    • High performance window replacement
    • Low emissivity reflective window film (to reduce unwanted solar gain in the summer and increase the R-value of windows in the winter)
  • Lighting
    • “Delamping,” i.e. permanently turning off/disconnecting unneeded light fixtures
    • “Relamping,” i.e. replacing inefficient light fixtures or lamps with high efficiency fixtures/lamps
      • Convert T-12 fixtures/lamps to T-8 or T-5
      • Relamp 32 watt T-8 lamps with 28 watt T-8
      • Eliminate incandescent bulbs
      • Convert all exit lighting to LEDs or switch to photoluminescent signs that require no electricity
      • Beware of retrofitting with indirect lighting – while classy looking it may require more fixtures and more wattage
    • Increase reliance on task lighting in order to decrease general illumination without adversely affecting productivity
    • Improve lighting controls
      • Occupancy sensors
      • Timers (stand alone or energy management system/EMS-interfaced)
      • Daylight harvesting sensors and controls including simple photocells
    • Convert outdoor lighting to high pressure sodium
    • Eliminate/reduce outdoor decorative lighting
    • Consider LEDs for general indoor and outdoor illumination (the technology is almost there)
    • Consider outdoor solar powered-LED light fixtures (this technology is also almost there)
    • Require white or off-white wall paints for maximum light reflectivity -- so adequate lighting levels can be achieved with minimum lighting wattage
    • When renovating spaces, design new lighting for less than 1.0 watts per square foot
  • Boilers
    • Replace old boilers with new high efficiency boilers
    • Do not oversize replacement boilers
    • Retrofit boilers with variable flame burners
    • Consider multiple high efficiency modular boilers to improve efficiency by better matching hot water heating loads
    • Consider replacing boilers with cogenerators (which also produce electricity)
    • Control boiler output water temperature with outside air temp reset so boiler does not need to heat water hotter than necessary
    • Retrofit boilers with flue gas/stack heat recovery
  • Chillers
    • Replace old chillers with new high efficiency chillers whose efficiency curve best matches your load profile
    • Do not over-size replacement chillers
    • Operate at peak efficiency (by adjusting water flow, load, condenser/evaporator water temps, etc.)
    • Replace old cooling towers with new high efficiency towers
  • Air conditioning
    • Replace older AC equipment with maximum efficiency models
    • Discontinue use of inefficient window units
    • Reduce AC operating hours
    • Turn off reheats and stop controlling humidity levels during the cooling season
    • Clean cooling coils on a regular basis
    • Maximize use of “free cooling” with economizer cycle
    • Use open windows and passive cooling when mechanical air conditioning is not needed
    • Close windows when air conditioning is in operation
    • In dry climates consider evaporative cooling
    • In humid areas consider desiccant cooling
  • Temperature control
    • Reduce temperature settings in winter
    • Increase temperature settings in summer
    • Maximize night, weekend and holiday temperature setbacks
    • Install tamper proof or remote thermostats
    • Control space temp remotely by EMS
    • If occupant controlled thermostats are required, then limit range of adjustment to ensure campus temperature policy compliance
  • Motors, fans and pumps
    • Adjust operating schedule to minimize run hours (review and update periodically)
    • Replace old motors, pumps, and air handling units with high efficiency
    • Control motors serving fans and pumps with variable speed drives (VSDs)
    • Operate VSDs at maximum acceptable turn-down; vary by time of day and occupancy; also vary by season
    • Convert constant volume fan system to variable air volume
    • Reduce outside air volume during morning warm-up cycle and where/whenever possible through damper settings and demand control ventilation
    • Reduce needless pumping by eliminating three-way by-pass valves
  • Laboratory Ventilation and Fume Hoods
    • Switch to a “green chemistry” teaching program that doesn’t require fume hoods
    • Turn off 100% outside air ventilating systems whenever possible, e.g. in teaching labs whenever classes are not in session; shut down or slow down related supply fans
    • Decommission/remove unneeded fume hoods and reduce fan system outside air volume
    • Eliminate unneeded fume hoods by using ventilated storage cabinets instead of hoods for chemical storage
    • Retrofit constant volume fume hood ventilation systems to variable air volume
    • Retrofit conventional fume hoods with low-flow hoods and reduce outside air volumes
    • Retrofit these systems with heat recovery
  • Heat recovery
    • Run around loops
    • Heat wheels
    • Heat pipes
    • Desiccant wheels
    • Air-to-air heat exchangers
  • Swimming pools/natatoriums
    • Pool covers (these significantly reduce the evaporation of pool water -- reducing pool heating boiler load as well as outside air ventilation and space heating requirements; they save chemical water treatment too)
    • High efficiency boilers for pool water heating
    • Limit natatorium ventilation to that required to meet code
    • If code ventilation requirements seem excessive in a particular application, consider applying for a code variance to reduce ventilation consistent with safety and proper humidity control
    • Install heat recovery
  • Energy Management Systems (EMS)
    • Switch to direct digital control (DDC) systems
    • Purchase EMS systems which are easy to program (so programming capabilities will be fully utilized by facilities staff)
    • Utilize and optimize use of EMS energy conservation programs, e.g.
      • Optimal start/stop
      • Night setback
      • Demand shedding
      • Remote programmed lighting control
  • Fuel Switching
    • Consider converting electric space and water heating to natural gas
  • Information feedback systems
    • Accessible display units that show energy use and savings can have dramatic results in energy use behaviors

Evaluating opportunities for natural gas-fired cogeneration and fuel switching from electric heating to natural gas requires a different mind-set when your ultimate goal is a reduction in carbon footprint (as opposed to simply reduced energy costs). While cogen and fuel switching are typically regarded as methods for improving overall efficiency (including thermal losses at utility power plants), on your campus these measures could decrease or increase your carbon footprint depending on the carbon intensity of your purchased electricity -- so it bears analysis.

Participating in the LEED for Existing Buildings (LEED EB) program may be an effective vehicle for moving your campus in more energy efficient directions – though be aware that not all LEED EB credits achieve energy or carbon reductions. For reducing GHG emissions, the most important credits in LEED EB are energy efficiency (EA Credit 1), building commissioning (Credits 2.1, 2.2, and 2.3), and renewable energy (EA Credit 4).

5.1.5 Performance Contracting

Energy performance contracting may be a critically important tool in your energy conservation bag of tricks. A good performance contract can allow your campus to do a decade or more’s worth of conservation in just a few years. Typically, these projects involve hiring an energy service company or ESCO, require little or no upfront money, and pay for themselves out of savings. Here are some guidelines for a good project:

  • Be diligent and careful in selecting an ESCO – the success or failure of your project depends on it
    • Choose an ESCO with ample experience on college and university campuses and a long list of satisfied customers
    • Choose an ESCO which is selling professional services and not representing a manufacturer and selling specific products
    • Pay careful attention to the people a prospective ESCO says it will assign to your project because one of the best guarantees of a good project is the caliber of the individuals assigned to the project team – be sure they know what they are doing, are easy to work with, and are very, very customer service-oriented
    • If your decision to hire an ESCO is based on certain personnel being assigned to your project, obtain contractual guarantees that these key staff people will not be shifted to other jobs
    • Insist on references for the team bidding on your project and not for another team within the ESCO or a previous iteration of the company
    • Select an ESCO that will allow you maximum flexibility in contract terms
    • Select an ESCO that welcomes campus participation in project design and construction
    • Select an ESCO that will provide full transparency of all fees and overhead and profit mark-ups (and of course avoid excessive fees/mark-ups but recognize that higher ones are associated with the performance contracting industry compared to the fee structure of a conventional architecture and engineering firm)
    • To help you evaluate and choose an ESCO, consider hiring an independent expert consultant who is loyal only to you (“the owner”) and understands how the performance contracting game is played
  • Projects should be comprehensive and thus incorporate a great number of varied energy conservation measures including quick payback projects that leverage or help pay for longer payback projects.
  • Consider including solar and other renewable energy projects in your performance contract and have the energy conservation measures pay for them
  • Make sure your school borrows the money to pay for the project so you can get the best rate vs. being required to use the ESCO’s financing (which will probably include a mark-up)
  • While you want to avoid high mark-ups, be careful about trimming them too far; you want the project to be “win-win” and have enough money in it for the ESCO to allow the ESCO to dig deep, carefully study all your campus buildings, and consider all viable energy conservation measures – and not simply cherry pick the easy stuff
  • Consider doing your project on a “cost plus” instead of “fixed cost” basis so that you do not pay more than you have to -- though be aware that the former approach shifts some risk to you and will involve more facilities staff time as you will be involved in all decision-making
  • Avoid guaranteed savings and shared savings provisions because you have to pay extra for them and may end up squabbling later with the ESCO over whether the guarantee has been met and whether the savings split is fair; a better approach to “guarantee” savings may be to verify that all the savings calculations for proposed measures are conservative and accurate, build into your project enough metering so you will know if it performed as advertised, and let the ESCO know you will publicize inadequate performance if that occurs.

Small campuses may be less attractive for ESCOs and increase the likelihood that projects may require some financial commitment to help a project get started. Check on state or utility incentives to help get funding for audits that are often the first step.

5.1.6 Aiming for “Deep Conservation”

In order to achieve significant GHG emissions reductions colleges and universities must think differently about energy conservation on their campuses. What is needed is not just an efficient campus but a super-efficient one. That means not just doing conservation but doing what might be called “deep conservation.” Even campuses that have already done extensive energy retrofitting and have model energy conservation programs need to do more. Resting on one’s laurels should not be an option.

Your school may be a leader and have already reduced energy consumption in buildings by as much as 30% but that is not enough. To meet the challenge of climate change you will need to redouble your efforts – and try to reduce energy consumption by another 10%, 20% or more.

To identify advanced strategies, techniques, and products for achieving deep conservation, your campus facilities unit may want to team up with interested faculty and students as well as an expert consultant or two and focus on one or more campus buildings in order to determine what is possible. Is a 40 or 50% cut in energy use possible and still have a livable, functional academic building? While constructing very low energy new buildings may be possible, the biggest, most important challenge for most institutions is figuring out how to significantly reduce the energy used by existing buildings. A campus climate commitment like the ACUPCC is your excuse to give it a try.

Of course, at some point our efforts will bang up against the limits of what can be done in existing buildings and there will be no more practical retrofitting options to exploit. In most cases, however, we are far from that circumstance.

5.1.7 Key Role of Facilities Management in Energy Conservation

Energy conservation on campus is everyone’s responsibility and a good program will get the whole campus community involved. Nonetheless, facilities management plays a key energy conservation role since maintenance staff control those pieces of equipment that use and can save the most energy. For this reason, effective energy conservation on campus requires a 100% commitment by facilities management.

Not only can facilities staff do the most to save energy, they need to set a solid example or others on campus will never get on the conservation bandwagon and help out where they can. An inspired facilities organization will inspire others. A lackluster facilities organization will turn everyone off.

To do their job, facilities management needs adequate resources and staffing including an energy officer whose job is to identify and carry out projects, get others to do the same, and generally catalyze as much energy conservation activity as possible.

While the role of facilities in achieving energy savings is highlighted here, it is also true that facilities managers and staff are essential for achieving other types of GHG emissions reductions including those which result from the installation of on-site renewables, green power purchasing, and energy efficient green design for new construction.

Facilities staff cannot do their job unless they are supported and empowered by top campus leadership. Without that support, they will be constantly looking over their shoulders anticipating criticism if they go too far in saving energy and cause someone to be inconvenienced. For example, when faculty, staff or students complain that a space previously overheated beyond the policy is no longer as comfortable, facilities staff must be supported for having remedied a wasteful practice. Exceptions to the rule must be rare and based on unusual and valid circumstances. Obviously, campus leadership also must set an example and not ask to be an exception to the policy.

5.1.8 Evaluating Energy Conservation Projects

As we consider deep conservation we must address barriers that stand in the way. Among these are inadequate leadership, funding, expertise, and organizational capacity as well as reliance on project evaluative tools and standards that emphasize short paybacks while dismissing longer payback measures. Deciding what evaluative tools, standards, and methods to use is important since your comparative evaluation of projects will help you decide which projects to do and when to schedule them. Deep cuts in GHG emissions require a different approach to project evaluation. (See the chapter on "Project Evaluation and Ranking" for more discussion of this topic)

Problems with Simple Payback

Prospective energy conservation projects are typically evaluated in terms of simple payback, i.e. installed cost divided by the annual savings -- where paybacks of 4 or 5 years are often considered attractive and acceptable. The simple payback approach is perhaps too simple and may rule out desirable projects that have longer simple paybacks or other benefits. These projects are essential to meeting your emissions reduction goals.

Simple payback analysis *fails *to consider:

  • Energy price inflation -- thus it under-estimates the cost savings potential of projects; moreover, as carbon taxes and peak oil kick in, the price of conventional energy resources will rise even quicker – thus magnifying the inadequacy of simple payback
  • The lifespan of a project -- thus it does not take into consideration the fact that projects which last longer will produce more savings after paying for themselves
  • Other costs and benefits that are relevant to sound decision-making, e.g. maintenance saving or costs, impact on health or comfort, pedagogic value, etc.

How can problems with simple payback be remedied? One possibility is switching from simple payback to slightly more sophisticated payback calculations that factor in anticipated energy price inflation. Some “crystal-balling” is required here but reasonable assumptions about future energy prices can be made. Another possibility is extending your acceptable payback threshold to 10, 15 or 20 years – taking care not to extend it past the lifetime of proposed energy measures or projects. A more sophisticated approach is life cycle cost analysis.

Lifecycle Cost Analysis

Lifecycle cost analysis examines and weighs the costs of a measure over its lifespan. It can be used to compare the costs of an existing system over a retrofit one – thus demonstrating the benefits of a retrofit measure in a more comprehensive way than simple payback. It can also be used to compare two or more retrofit options.

A description of lifecycle cost analysis is available in the Whole Building Design Guide which notes that this type of analysis considers these costs/benefits:

  • Initial Costs—Purchase, Acquisition, Construction Costs
  • Fuel Costs
  • Operation, Maintenance, and Repair Costs
  • Replacement Costs
  • Residual Values—Resale or Salvage Values or Disposal Costs
  • Finance Charges—Loan Interest Payments
  • Non-Monetary Benefits or Costs

The last category of benefits and costs shown above allows life cycle cost analysis to consider a wide range of other factors. For example, a lighting retrofit might save energy and energy dollars *plus *improve safety – where the latter improvement is very important but not easily quantified or stated in dollars. Similarly, an HVAC retrofit might save energy and energy dollars *plus *improve comfort and indoor air quality -- which makes people happier, healthier and perhaps more productive, important factors not easily quantified or monetized.

With lifecycle cost analysis you can also consider altruistic factors, i.e. societal or environmental impacts that wouldn’t otherwise figure into your cost vs. savings calculation. An example might be the impact of a measure on climate, local air pollution, noise, or on the fate of mountain tops in West Virginia that are now subject to destruction by coal mining.

**Factoring in the Avoided Cost of Unneeded RECs or Carbon Offsets **

Colleges and universities that are committed to climate neutrality or sharp cuts in GHG emissions may eventually choose to mitigate remaining fossil fuel use and GHG emissions with purchases of green power or carbon offsets. It makes sense, then, especially for ACUPCC institutions, to credit energy conservation measures with the savings associated with those anticipated avoided purchases. This can be done in a lifecycle analysis. It can also be done in a modified payback analysis – though in both cases you will need to use an assumed cost for the value of the avoided REC or carbon offset. (REC is shorthand for renewable energy credit or certificate, which is generally what one purchases when obtaining green power; see the "Buy Green Power" section for more on this topic)

While it is not possible to know the exact future cost of these instruments, you can estimate those costs by checking with existing vendors to identify a price to use in your calculations. For example, RECs on the national market generally cost 1 to 3 cents per kilowatt hour. TerraPass and the Carbon Fund are currently selling carbon offsets at $10 per ton of carbon dioxide emissions. While using these numbers may be misleading because the markets for both RECs and offsets will evolve (and prices will change), the principle still holds true, namely, that energy conservation can reduce the need to buy RECs or offsets and those avoided future purchases mean avoided future costs. If your school will not be purchasing RECs or carbon offsets for a few years, you can allow for that by excluding their avoided costs in your savings and payback calculations until the year you think they would kick in.

Incidentally, factoring in REC and carbon offset savings into lifecycle or payback analyses can and should also be done when financially evaluating a prospective PV or other type of on-campus renewable energy project – since those projects also reduce the amount of RECs or carbon offsets your school may need to purchase.

Note: the ACUPCC Carbon Offset Protocol provides additional guidance on offset purchasing; also see the "Carbon Offsets" section of this manual.

**Comparing Measures Based on CO2 Reduction Efficacy **

It also makes sense to evaluate prospective energy conservation measures in terms of their relative efficiency or efficacy in producing GHG emissions reductions. To do this, projects can be compared in terms of a cost/offset ratio or how much it costs to produce a metric ton reduction of carbon dioxide emissions ($/MTCO2e/yr). This analysis can be done in terms of net present value to take into account the time value of money.

Care, however, should be taken not to focus initially only on those measures which have the most attractive cost/offset ratio because such an approach may make it more difficult to complete the less attractive measures at a later date. The same logic applies when comparing projects on the basis of payback.

See the chapter on "Project Evaluation and Ranking" for further discussion on using cost/offset ratios to compare and prioritize projects.

5.1.9 Avoid the Short Payback Trap

It is often assumed that it makes most sense to start with energy conservation measures that are easiest to do and have the shortest simple paybacks, i.e. the proverbial “low-hanging fruit.” The problem with this approach is that if you harvest all the low hanging fruit first, then all you have left is the high hanging fruit – and reaching that fruit can be pretty difficult since it has longer paybacks and thus appears to be financially unattractive.

The short payback or low hanging fruit trap can be avoided by combining the most cost-effective energy conservation measures with less cost-effective measures. This is typically done in comprehensive energy conservation performance contracts. Lighting retrofits may have short paybacks while more capital-intensive retrofits like installing heat recovery systems or new boilers or chillers may not. If both types of measures are combined in the same project, the end result can be a relatively attractive combined payback and thus an overall project which is relatively easy to financially justify. This approach allows short payback measures to leverage or in essence finance long payback measures.

The strategy of combining short and long payback projects can also be used to finance renewable energy projects like photovoltaic arrays that may have a very long and financially unattractive payback even after taking advantage of incentives that bring down project costs. In a large multi-million dollar comprehensive energy conservation project, conservation measures that payback relatively quickly can be used to leverage a PV array that may payback in 25 or more years. Moreover, while the cost of a large PV array may be substantial if viewed in isolation, even a $500,000 system may shrink to insignificance when viewed in the context of a large multi-million dollar comprehensive energy performance contract.

The second way to avoid the short payback trap is to create a revolving fund that is funded by energy savings that are then available to fund later projects that have longer paybacks.

5.1.10 Revolving Funds

A revolving fund works by placing all or some of the savings produced by energy conservation projects and measures into an account that is then used to fund other projects. This same account could be the repository for an annual budgetary allocation from your administration to help finance your energy conservation projects. It could also be the place where energy incentive monies are deposited.

Since conservation is so important and funds for projects are generally limited, it will be necessary to protect the revolving fund from being raided for purposes other than conservation. A clear understanding of how this fund may be used is essential. For projects which are a mix of capital improvement and energy conservation, only the premium cost associated with maximizing efficiency should be charged to the fund. The revolving fund’s manager should establish a set of criteria for evaluating eligible projects so that only the best projects which would otherwise not be done get funded from this source.

Another challenge in establishing and maintaining a revolving fund is turning “avoided costs” into real dollars when a budget crunch comes. When an energy conservation measure is employed, it does not produce a pot of money. Instead it produces savings or avoided utility budget costs. To fund your revolving fund, you may need an agreement with your chief budget officer that allows you to identify and transfer energy savings from the surplus in your utility budget caused by conservation measures. This may work well until energy prices unexpectedly rise or if campus energy consumption is greater than anticipated because of an especially cold winter, for example, causing your utility budget to go into deficit mode -- even though the conservation projects you implemented are nonetheless producing savings. Thus, when utility budgets go into the red, transferring savings into your revolving fund may be “politically” more difficult to accomplish. This problem can be solved by anticipating these circumstances and having an agreement in place to transfer savings irrespective of the condition of the budget.

5.2 Appropriate Heating or Power Plant Fuel Choices

5.2.1 The Problem with Coal

Unlike natural gas or oil, coal is mostly carbon – so when it is oxidized or burned, the result is mostly carbon dioxide. Thus from a climate protection point of view, quitting coal is critically important. That rule applies to the coal you may burn in your campus heating or power plant. It also applies to the embodied coal in purchased electricity.

Leading NASA climatologist James Hansen and others have argued that to effectively put the brakes on climate change we must stop burning coal except where carbon dioxide emissions are captured and permanently sequestered – a condition which does not presently apply to coal-burning at any college or university and, with the exception of perhaps a small number of well-funded large university campuses, is unlikely to do so in the future -- given the complexities, costs, and uncertainties of carbon capture and storage.

Of course, quitting coal is more easily said than done. There are at least two big hurdles – the potentially much higher cost of alternative fuels (e.g. natural gas, biomass, etc.) and the cost to build a new campus heating/power plant or retrofit an old one.

Many colleges and universities, especially those in coal states in Appalachia and the Midwest, have traditionally used coal for what seemed to be good reasons before we became aware of the problem of climate change. Coal is, after all, plentiful and cheap – though during the first half of 2008 increasing international demand caused the price of coal to double before returning to normal once the global economic meltdown occurred later in the year. Higher coal prices may return once the world economy gets back on track. Moreover, coal prices will definitely rise to much higher levels as effective cap and trade or carbon tax regimes are disproportionately applied to coal to actively discourage its use. Coal mining presents a raft of troubling environmental and health issues as well. And as many facilities managers know, coal is dirty to handle and can have adverse health impacts on facilities staff – a reality campuses that burn coal may not want to admit for liability reasons.

So it makes sense to look at alternatives to coal burning – perhaps making plans to convert your power plant once the economy picks up and revenues become available. Schools in coal-producing regions of the country may want to expand their examination of alternatives to coal to include research on transitioning local communities away from coal mining and, if needed, direct assistance to workers and communities affected by this transition.

There can be a silver lining to quitting coal. Switching to a higher price heating fuel will increase the incentive your campus has to implement energy conservation measures to reduce your heating load. And those measures will further reduce your carbon footprint. In any event, schools committed to make significant reductions in GHG emissions with on-campus coal plants can’t avoid this very difficult issue.

5.2.2 Alternatives to Coal

What fuel options besides coal exist for campus heating or power plants? The obvious traditional one is natural gas. Less obvious though more climate-friendly choices are biomass, landfill gas, and geothermal.

Natural Gas
Natural gas industry advertisements have told us for years that natural gas is clean and efficient. In fact, it is a fossil fuel and even burning it efficiently produces ample quantities of carbon dioxide that contribute to climate change. To avoid the worst consequences of climate change we will need to reduce our reliance on all fossil fuels including natural gas. Nonetheless. natural gas is the cleanest of fossil fuels from the point of view of conventional pollutants as well as carbon dioxide emissions. On a BTU basis (CO2/BTU), natural gas produces about half the GHG emissions as coal. Thus switching from coal to natural gas combustion is a step in the right direction though not a long term fix. While coal is regarded as cheap and plentiful, natural gas supplies are more constrained and natural gas has been relatively expensive until the recent economic downturn.

Campus planning involving heating or power plant fuel choice should anticipate future carbon tax penalties. These penalties will close the cost gap between coal and natural gas. It is also important to note that natural gas can be burned more efficiently than coal.

Cogeneration or “combined heat and power,” an option for coal and natural gas, further increases the efficiency of fuel use (especially if combined cycle technology is used) and thus can play an important role in lowering costs and making natural gas use more affordable. However, a note of caution: as previously mentioned, while cogeneration is generally regarded as an energy efficiency measure, implementing it at any given school could decrease or increase its carbon footprint -- depending on (a) the carbon intensity of the fuel used to cogenerate and (b) the carbon intensity of the purchased electricity cogenerated electricity replaces.

Biomass
Biomass fuel consists of organic material such as wood chips, oat hulls, corn husks, etc. Finding a long-term reliable supplier with enough fuel from those sources to power campus heating or power plants can be a challenge. Ensuring that the biomass is produced sustainably is also a challenge. Other challenges associated with biomass are biomass’ relatively low heat density (requiring greater volumes of fuel), transporting and handling issues, and its air emissions and ash waste products.

Biomass is not only renewable but also theoretically carbon neutral because the carbon that’s released into the atmosphere when biomass is burned can be captured and sequestered into new biomass as that biomass grows. Sustainable biomass presumes that annual biomass production equals consumption and is accomplished without environmental damage, e.g. cutting down forests. Since some fossil fuel inputs are generally involved in growing, harvesting, chipping, and transporting biomass fuel, it can be argued that biomass is not actually carbon neutral despite often being regarded as such. Calculating the life-cycle net carbon emissions of biomass-based heating or electricity production would be a great project for students and faculty.

Sustainable biomass can include waste products like wood waste from furniture plants, urban tree trimmings, or clean wood extracted from municipal solid waste, and agricultural crop waste. While the waste-to-energy industry sometimes claims that general municipal solid waste is an acceptable biomass fuel, it is not regarded as such by environmentalists because of the dirty air emissions and toxic solid waste by-products its combustion produces and because burning municipal solid waste generally undermines municipal recycling programs.

Before proceeding with plans to convert to biomass campus heating or power generation it is essential that a fuel availability study be conducted. While a consultant can be hired to perform this study, it could be a great project for students with support from faculty and facilities management staff. Students could study the net availability of suitable biomass resources within a given distance from campus. This research would examine existing resources as well as the potential biomass resource if a market for biomass were created by demand from your proposed plant. Students could identify sustainable forestry or crop practices that your school could require for biomass purchases including consideration of the Forest Stewardship Council’s best practices. If you proceed with a biomass plant, once it is up and running students can study the supply chain to determine and evaluate what is actually happening on the ground. This is but one example of an operational step toward reduced carbon emissions that provides a unique and important learning experience for students. Your CAP should identify and utilize these.

While converting your heating or power plant from coal to biomass may be a long-range strategy due to the costs involved, in the meantime – depending on boiler type -- it might be possible to co-fire biomass and thus reduce GHG greenhouse gas emissions. Co-firing generally involves displacing some coal combustion by burning biomass and coal together. The National Renewable Energy Laboratory has published a useful factsheet on biomass cofiring.

Middlebury College provides an example of biomass cogeneration while the University of Iowa provides an example of co-firing oat hulls.

Landfill Gas
Landfill gas is methane produced by the decomposition of garbage in landfills. Since methane is a powerful GHG gas which on a mass basis and 100 year time horizon has over 20 times the global warming potential of carbon dioxide, it is important that it not be vented to the atmosphere. Collection systems can be installed in landfills to harvest methane. It is then scrubbed and often burned on-site to generate electricity or both heat and electricity. It can also delivered elsewhere via pipeline. While burning landfill gas produces carbon dioxide, it also prevents methane emissions – and thus has the effect of a substantial reduction in GHG emissions. While not readily available to all college campuses, landfill gas can be a suitable fuel for campus power plants or any kind of boiler or cogenerator.

University of New Hampshire offers an example of campus cogeneration using landfill gas.

Geothermal
Geothermal energy takes different forms. It may be possible to tap very hot water or steam through deep wells and use that heat energy to heat buildings or generate electricity – though this type of geothermal is very site specific and would not be available to many campuses. In contrast, ground source heat pump (GSHP) systems will work in most areas. They also rely on wells but they use the earth as a heat source and heat sink through the use of electrically powered heat pumps. Heat pumps move heat using a refrigerant gas and a refrigeration cycle much like the one used in a home refrigerator. Usually GSHP systems are used to heat and cool individual buildings – though if you drill enough wells, run enough heat exchanger pipe, and have enough heat pumps, it is theoretically possible to abandon a coal-fired power plant and heat and cool an entire campus this way. If the heat pumps are run on electricity generated from wind turbines or another renewable energy source, you have carbon-free heating and cooling.

Oregon Institute of Technology offers an example of geothermal heating and electricity production on campus and Ball State University provides an example of GSHP replacing a co-fired campus power plant.

Of course, irrespective of the fuel type used by your heating or power plant, you can reduce your carbon footprint and fuel costs by reducing the amount of fuel you burn. That can be done by reducing your campus energy load through energy conservation efforts.

5.2.3 Reducing the Carbon Footprint of Oil Burning

Many sites have limited heating fuel choices and rely on fuel oil as a primary heating source. If cleaner burning natural gas is available nearby, the cost of connecting to it and upgrading boilers & burners to use natural gas can be calculated. A reduction in GHG emissions will be a certainty with this change because on a BTU basis (CO2/BTU) natural gas emits 30% less CO2 than does fuel oil. Also, it may be possible to burn natural gas – especially when cogenerating -- more efficiently than oil, thus further reducing GHG emissions.

Where switching to natural gas isn’t feasible, consider the use of #2 oil vs. the dirtier (but less expensive) #4 or #6 types. On a BTU basis, #2 oil emits 7% less CO2 but emissions reduction will be greater than that because #2 oil does not have to be heated in storage (a requirement for #4 and #6 oils in colder climates to allow the oil to be pumped).

Of course, if you are need of a new power plant or are prepared to replace your oil-burning boilers, then you can consider a wholesale switch to biomass, landfill gas or geothermal.

5.3 Install Renewable Energy Technologies on Campus

Conservation and efficiency can take us far but not all the way. Even after we have reduced our energy load to a bare minimum, we will still have to meet that remaining load with some form of energy. In order to achieve climate neutrality or deep cuts in GHG emissions, campuses will need to transition as much as possible to carbon-free renewable energy technologies – solar, wind, biomass, geothermal, and hydro (though the latter is pretty much tapped out in most regions). We can either build renewable energy capacity on campus or buy green power. This section discusses on-campus renewable energy sources for non-heating and power plant applications. When performing an economic evaluation of these technologies, consider the dollar savings associated with avoiding future costs for RECs or carbon offset purchases. See the "Paying for Campus Renewable Energy Systems" section for resources describing renewable energy financing options.

5.3.1 Photovoltaic Solar Electric Arrays

Many campuses are installing photovoltaic (PV) solar electric arrays. While rarely as cost-effective as energy conservation, PV becomes more cost-effective when conventional electric rates are high and ample incentives are offered by state government or local utilities.

Obviously, the amount of available sunlight is another important factor though PV can work well in all areas. Where there is less sun, you compensate by adding panels to meet a given load. This adds cost and stretches out payback but it works. Where snow may cover panels during winter months, panels can be tilted to shed snow or PV array output can be pro-rated downward to allow for a number of weeks or months when output is nil. The performance of grid-interconnected PV is generally measured in terms of annual power production and most PV production occurs during the warmer months when days are longer and there is less cloud cover. In areas where winter days are cold and clear, angling panels to take advantage of those conditions becomes more important.

There are a variety of financial models for installing PV on campus. Your school can design, purchase and install its own system -- typically with the technical assistance of a consultant or supplier. The relatively high cost and long payback of this kind of investment can be tempered by incentive dollars that reduce the initial or “first cost” of the system. Another financing strategy is to include the cost of the solar energy system in a larger self-financing energy conservation program and, in essence, allow the energy conservation measures (and the dollar savings they produce) to pay for the solar.

Another approach for installing solar on campus is signing a power purchase agreement (PPA) with a renewable energy power provider who will install and own a PV system located on your campus. A PPA will oblige a school to purchase power from the PV system for a number of years at rates established by the contract. The primary advantage of this arrangement is that the school is not responsible for the installation, operation, maintenance, or cost of the PV system. Also, this arrangement may allow the energy supplier to take advantage of tax credits which may not be available to the campus.

Maximum output from PV arrays occurs mid-day on hot summer days – precisely the time when regional grids in many areas are under strain because of very high air conditioning loads. At these times, hourly rates for electricity may be much higher than average rates. This coincidence suggests that an analysis of PV cost-effectiveness should be sophisticated enough to factor in the additional dollar savings associated with avoiding that very expensive conventional electricity. PV arrays can also reduce peak demand and peak demand charges. PV dollar payback may still be relatively long though factoring in these additional savings will shorten it somewhat.

In order to claim a CO2 reduction from a campus owned and operated PV system or from a PV PPA, you must own the renewable energy certificates or RECs associated with the output of your system. In the case of a PV system your campus owns, you must not sell the RECs it produces but instead must “retire” them. In the case of a PV PPA, you must buy not only the power produced by the system but also the RECs (see the "Buy Green Power" section for an explanation of RECs.)

AASHE maintains a list of campus PV installations.

5.3.2 Other Solar

Other on-site, on-campus solar options include:

  • Passive solar
  • Daylighting
  • Solar hot water

Not only can all three of these technologies be considered for new construction, all three can be either made to work or installed in existing buildings. For example, you may already have buildings with rooms or corridors with ample south-facing glass that allows solar gain during the winter months. This gain may be a nuisance now, causing localized over-heating. Building occupants may be fighting that sunlight with pulled down shades. Your maintenance staff may have solved the problem by installing reflective window film to block the sunlight from entering the building. An alternate approach would be to let the sunlight pass through the windows and put that heat to work by installing thermal mass to store it for use later in the day or by modifying the HVAC system so the heat is captured, transported, and used in another part of the building. Engineering or architecture students may want to study passive or active solar heating options for that kind of campus building as a class or volunteer project.

Similarly with daylighting, you may already have daylit spaces but are not taking advantage of their energy saving opportunity because of inadequate controls on electric lighting. Installing photocells or sensors may be all it takes to keep electric lighting off when daylight from the sun is adequate to illuminate those spaces. Facilities staff or students can survey the campus to look for opportunities of this kind.

Solar hot water systems can be more cost-effective than PV solar electric systems yet are generally less common. Why is that? Maybe it is because piping is harder to install than wiring. Maybe it’s because fewer incentives are available. Also, unlike PV (whose output can always be used by the building it’s mounted on or the local power distribution system its connected to), solar hot water systems must closely match production with demand. And hot water needs may not coincide with those times when solar hot water systems readily produce hot water. On most campuses, hot water demand predominantly occurs in the fall, winter and early spring when the fall and spring semesters are in session. However, in many parts of the country solar gain is not ideal during much of that period: the sun is low in the sky, days are short, and there may be lots of cloud cover or snow. Also, while most campus buildings have hefty appetites for electricity, not all campus buildings have adequate hot water loads to justify a solar hot water system. Buildings with above average hot water needs include athletic facilities, student residences, and food service facilities.

While solar hot water presents some challenges, it is a viable option for campuses interested in demonstrating solar energy. If the “first cost” of such a system is daunting, consider a power purchase agreement with a solar provider that would build, own, and operate “your” solar hot water system while selling you its hot water output. Students and faculty can study the possibility of using solar hot water technology for seasonal solar storage – collecting and storing solar heat collected in the sunny summer for use in the cold cloudy winter.

5.3.3 Wind Energy

Some colleges and universities have installed wind turbines on or near campus to meet a portion of their electricity needs. The huge size of the most efficient turbines, i.e. utility scale turbines whose blades reach as high as 400 feet, make them “out of scale” to the rest of a campus and hence there can be challenges to installing them on smaller campuses or near campus buildings. These giant turbines are often better suited to be installed on the periphery of a large campus or on outlying campus property. Some campuses may own distant property and that too can be considered for wind turbine installation -- though in that case getting the power to campus may involve additional delivery costs. It is generally financially advantageous to install wind energy capacity on the campus side of the electric meter.

There are a variety of wind turbine financing options to consider – from campus ownership to buying the output of an on-site turbine through a power purchase agreement – with advantages and disadvantages to each. If your campus is pursuing wind energy, it is important to design your project to take advantage of federal and state incentives, tax credits, and tariff mechanisms which are now in place and are being developed to promote wind energy as well as other renewable energy technologies. As with PV, the campus must own the RECs produced by the turbines in order to take credit for GHG emissions-free power – though it is the introduction of electricity from the turbine (not the RECs) which actually changes the mix of generation away from polluting fossil fuels (see the "Buy Green Power" section for an explanation of RECs.)

Smaller turbines which can be mounted on buildings present another on-campus wind energy option. These can make a statement and have educational value – though their output is likely to be very low given their small wind swept areas.

If your intent is to generate cost-effective electrical power from a wind turbine, then be sure to have a proper professional wind assessment done; it doesn’t protect the climate to waste a lot of steel production putting an industrial wind turbine on an unsuitable site with little wind. This is an exceptionally wasteful mistake to make because the amount of power in the wind is a function of the cube of the wind speed. Thus, even an additional meter/second in wind speed can make a huge difference! Of course, there also will be a need for training turbines, particularly at technical and community colleges, and these obviously need to be placed close to where students are. To avoid waste, these should be smaller analogs of the largest industrial turbines. Refurbished models may be cost effective for this purpose.

AASHE maintains a list of campus wind installations.

5.3.4 Biomass

See the "Alternatives to Coal" section for discussion of biomass as heating or power plant fuel. Also, students – with help from campus facilities management and relevant academic departments (e.g. chemical engineering) -- may be interested in producing biodiesel on campus using waste fryer grease from campus food service and local fast food restaurants. Students at Oregon State University provide an example of the latter.

5.3.5 Geothermal

Geothermal energy involves tapping underground reservoirs of hot water or steam for space and water heating as well as for electricity generation. Alternately, water can be pumped underground to be heated by hot rocks – though hot rock geothermal generally requires very deep wells ). Geothermal energy resources of this nature are very site specific and not available to many colleges and universities.

In contrast, geothermal or ground source heat pump (GSHP) systems are almost universally applicable. They make use of shallow wells or bore holes (up to a few hundred feet deep) to access the relatively constant temperature of the earth just below the frost line. With the help of electrically powered heat pumps and closed or open water/glycol pipe loops which exchange heat with the ground, these systems use the earth as a heat source and sink -- extracting heat from the ground in the winter and rejecting/storing it there in the summer. As such, geothermal heat pump systems are a kind of renewable energy technology. These systems can also be regarded as energy efficient technology. Unless flowing groundwater is present near the wells, applications need to have both heating & cooling loads to avoid a long term change in the ground temperature.

GSHP systems are applicable to both new buildings and existing buildings. To be cost-effective, they are best suited to buildings which require mechanical air conditioning during the warmer months. If you are striving for passive cooling, then a GSHP system may not make sense. These systems require electricity to run compressors, pumps, and fans though are much more efficient than electric resistance heating. Zero-energy new buildings become a possibility with this technology since it can be powered by electricity generated by PV panels. Achieving this measure of performance on a retrofit basis is very difficult. Depending on the CO2 emitted by your electricity source, GSHP can have a very positive impact on reducing a building’s carbon footprint vs. fossil fuel heating.

Oregon Institute of Technology provides an example of a campus geothermal installation. The National Wildlife Federation provides additional examples of geothermal heat pump-heated and cooled buildings.

5.3.6 Fuel Cells

Stationary fuel cells which generate electricity and heat are another potentially renewable option for campus installation However, fuel cells powered by natural gas – which is the norm -- are neither renewable nor carbon free. To use a fuel cell to produce GHG emission-free electricity and heat, a carbon-free source of hydrogen would be required. That could come from a hydrolysis process (which splits water into hydrogen and oxygen) that is powered by renewable, carbon-free electricity from either wind turbines or PV panels.

Fuel cells that use natural gas can function as an energy conservation measure and in that capacity reduce GHG emissions.

AASHE maintains a list of campus stationary fuel cells.

5.3.7 Renewable Energy Educational Displays

In all cases, it is desirable to accompany an on-campus renewable energy installation with an education program or display. Such a display could include metering and monitoring to show real-time performance of the system. This can be conveyed via a kiosk or website or both. Incorporating an educational component contributes to the goal of introducing sustainability and climate change into the curriculum.

It may also be possible to design an on-site solar, wind or biomass system so that it can be used for student or faculty research.

Maximizing the educational and research value of on-site renewable energy installations is a good idea in itself plus it helps compensate for the fact that in many cases these projects are very expensive and have longer paybacks and produce less carbon mitigation than would energy conservation.

University at Buffalo's “Energy for the Future” educational display is an example of a campus energy display.

5.3.8 Paying for Campus Renewable Energy Systems

The preceding discussion about on-site renewable energy options includes some discussion of financing options. For more information on financing on-site renewable energy technologies, see The Business Case for Renewable Energy: A Guide for Colleges and Universities by Andrea Putman and Michael Philips (2006), Alternative Energy Economics by Michael Philips and Lee White (2009), and the Database of State Incentives for Renewables and Efficiency.

5.4 Buy Green Power

Producing on-campus carbon-free, renewable electricity is difficult and producing enough of it to make a real difference is even harder. That is why many campuses have begun purchasing green power. Institutions striving for carbon neutrality will eventually need to generate electricity on-site with carbon-free sources and shift purchased electricity to green power purchases, or buy carbon offsets to mitigate the carbon emissions embodied in continued conventional power generation and purchases.

The U.S. Environmental Protection Agency Guide to Purchasing Green Power is a useful resource. Also, the EPA's Green Power Partnership provides campus examples of green power purchasing.

5.4.1 Benefits of Buying Green Power

There are a variety of benefits associated with buying green power. Green power purchases can:

  • Bolster the development of additional green power generating capacity, thus shifting the mix of generation types away from fossil fuel generation and reducing carbon and other harmful emissions
  • Contribute to the construction of specific renewable energy generators (such as a new local wind farm) if green power is purchased through a long term contract with a specific developer
  • Provide a financial hedge against price volatility of conventional electricity, especially if you purchase green power on a long term contract
  • Demonstrate civic leadership
  • Provide public relations benefit
  • Increase campus morale
  • Serve an educational value

5.4.2 What You Are Buying -- RECs or Green Tags

Green power purchasing typically involves buying renewable energy credits or certificates, referred to as “RECs” or “green tags.” These are purchased in increments of 1,000 kilowatt hours (1 REC = 1,000 kWh or 1 megawatt hour) and represent the “environmental attribute” associated with renewable power. RECs are certified by an independent agency (e.g. Green-e) to guarantee their actual production from a qualifying renewable energy source and to insure that they are not double-counted. Qualifying sources include solar electric, wind, geothermal, and certain types of hydro, biomass and hydrogen fuel cell-derived power.

RECs are sold on “compliance” and “voluntary” markets and typically cost 1 - 3 cents per kWh, a premium cost over and above purchased electricity. Price differences can be attributed to demand, location, provider, and green power generation source. Given the volume of institutional green power purchases, colleges and universities can expect better pricing than residential and small business owners.

Compliance markets are created by policies such as renewable portfolio standards that require electric utilities to supply increasing percentages of power from renewable sources. Colleges and universities participate in voluntary markets, i.e. pools of customers that voluntarily choose to go green.

While RECs are the most common vehicle for purchasing green power, there is some skepticism about them. Some argue that REC purchasers receive nothing of value other than bragging rights -- despite REC certification regimes by Green-e and state public utility commissions. In many cases – because there is no requirement of “additionality” -- it is not clear whether a given green power purchase is responsible for catalyzing additional generation of renewable power (thus suppressing fossil fuel generation and reducing GHG emissions). Potential customers may wish to ask for evidence that their green power purchase will produce a GHG emissions reduction “in addition” to what would have occurred anyway.

Over time the renewable energy market may move beyond RECs, but for now campuses as well as business and residential customers interested in green power usually deal with RECs. Fortunately, there are strategies that can be used to increase the odds that your green power purchase really produces an environmental benefit. Some of these strategies are described in the next section.

5.4.3 Maximizing the Benefit of Green Power Purchases

Not all green power is equal. For example, if you are buying biomass-generated electricity, due diligence requires that you examine the source of fuel to insure that its production does not involve forest destruction or other negative environmental impacts. Also, not all green power is carbon-free. A case in point is biomass-generated power since fossil fuels are typically consumed in the process of producing, transporting and processing biomass fuel. Wind, on the other hand, is GHG emissions-free except for the fossil fuel used in making and installing the wind turbines themselves, a carbon debt which wind manufacturers say is paid back within a few months of operation. While these embodied energy issues are generally not considered in campus carbon accounting, investigating them would provide an interesting learning experience for students and faculty.

Hopefully, colleges and universities are buying green power not simply for bragging rights but are doing so out of genuine concern for sustainability. If your purchase of green power does not actually lead to the development of more green power capacity (and thus contribute to a shift in the power generation mix from dirty fossil fuel to a greater percentage of clean renewable-generated power), then no reduction in GHG emissions has been achieved and no environmental benefit has occurred. Thus, it is important that schools consider, as an essential decision-making criteria, the likeliness that a given green power purchase will in fact leverage new renewable power development. It is critically important that it does.

To clarify, let’s see how this might play out in the real world. Perhaps you could buy qualifying hydro power at a cheap price but that purchase is unlikely to motivate developers to build more hydro capacity because additional hydro opportunities are not available. If your other option is to purchase wind energy, whose RECs might cost more but whose purchase will stimulate the construction of the next wind farm, then this perspective says you should buy wind. One can easily imagine some difficult decision-making on campus given the challenges and costs associated with achieving significant cuts in GHG emissions. You could claim greater progress in mitigating carbon emissions by buying a lot of cheap RECs but the progress you are claiming would be imaginary if your REC purchases are not actually helping to shift the mix of generation.

Let’s take this line of thought a few steps further. Are there ways of buying RECs that make it even more likely that that next wind farm, for example, is built? The answer is a resounding “yes!” The best way to leverage new wind capacity is to “buy” and build that new wind farm yourself. The next best approach is to buy wind-generated RECs on a long term contract. With a long-term REC contract in hand a wind developer can secure lower cost financing, vastly increasing the odds that the next wind farm is built. That’s what you want to see happen.

You can further increase the odds that your green power purchase will increase renewable energy capacity by purchasing wind-generated green power on a long term contract specifically from a planned wind farm that is not yet built. This may seen counter-intuitive but this strategy may be effective because it compels the developer to build additional renewable capacity in order to obtain your business. Your ability to leverage that next wind farm grows even further if you also commit to a long-term contract for the electricity output of the wind farm (the “commodity”) as well as the RECs. This approach may also allow you to lock in flat or more level and predictable electricity pricing – thus providing a hedge against future electricity price volatility.

Yes buying green power gets complicated but the bottom line is this. As the renewable energy market evolves, colleges and universities as well as other customers will have new options for buying green power. Smart buyers of green power will chose those options most likely to increase state, national and global renewable energy capacity.

5.4.4 Complementing Green Power Purchasing with Conservation

Installing or buying green power and doing energy conservation are GHG mitigation strategies that can complement and synergize each other. Big doses of conservation will save money and reduce your energy load, thus saving more money by decreasing the amount of green power you will need to produce or buy in order to displace fossil fuels. Plus conservation savings can be used to buy green power – thus offsetting those costs. Eliminate waste and reduce those energy needs! There is a lot of magic in energy conservation!

5.5 Maximize Space Utilization to Minimize or Avoid New Construction

5.5.1 Wasting Space on Campus

While new construction is sexy and having a LEED Gold or Platinum building on campus certainly gives you real bragging rights, the reality is that each new building adds to your campus carbon footprint unless it is a zero-energy building or it replaces a building that used more energy. While zero-energy buildings may eventually become the norm, with very few exceptions they are not here yet. New campus buildings, even those which are LEED certified or better, may turn out to be energy hogs – and thus are responsible for significant increases in the size of campus carbon footprints, increasing the difficulty of achieving carbon reduction goals.

Colleges and universities committed to reducing their carbon footprints need to look at new construction in a new way. They can save energy dollars and reduce carbon emissions by maximizing the utilization of existing space and avoiding new construction. While it may be difficult to imagine a president of a college or university resisting new construction (since new buildings are often viewed as legacy accomplishments), that’s what is needed.

On many if not most of our campuses inefficient space utilization is the norm. The most desirable spaces may be intensively utilized and fought over while less desirable spaces are cast off and sparsely occupied. Over time, as new buildings are constructed and departments and offices move into those glitzy, high prestige spaces, the areas they leave behind are taken over by existing personnel and offices. What happens is that everyone spreads out with the net effect of decreasing space utilization density. Ever greater areas are “used” while activity and output stays roughly the same.

Our campuses tend to have structural space inefficiencies as well. Consider the academic calendar. At many schools it is common to see beautiful campuses mostly barren of students, faculty and most academic programming for the entire summer -- beginning in early May and stretching to late August. Meanwhile, because staff are still present and departmental offices are still open, all buildings are considered “occupied” and all HVAC equipment is running. This is the way colleges and universities do business but from an energy and climate perspective it does not make sense.

The inefficiency of faculty offices deserves special mention. Faculty members generally have their own offices but these offices may be utilized only few hours a week during 15-17 week spring and fall semesters and completely unoccupied otherwise – all the while these spaces are heated and cooled twelve months of the year as a consequence of building HVAC system design. This is no way to do business if you are in the business of reducing your carbon footprint down to zero!

5.5.2 Strategies for Addressing Poor Space Utilization

There are a variety of ways to tackle these problems or, alternately, take advantage of these opportunities – perhaps none are easy but all are possible. Here are some ideas:

  • When a new building is proposed, first determine whether there is a way to meet the alleged program needs for the building by reconfiguring and better utilizing existing space.
  • During break periods, especially intersession or the December holiday break, encourage or require everyone to take vacation time and put the campus in a shutdown mode as much as possible.
  • HVAC modifications can be implemented for faculty offices so these spaces stop being heated, cooled, or ventilated when unoccupied (which is most of the time).
  • If your school is committed to an enrollment growth scenario, it might be possible to accommodate many more students without new construction if you operate academic programs at full tilt year round and thus make better use of existing buildings over the summer.
  • More aggressive scheduling including starting classes earlier or even on Friday afternoons can defer the need for a new building. (Since earlier classes may be resisted by students and faculty alike, they may need to accompanied by rules for earlier bedtimes!)

The Society of College and University Planning (SCUP) offers a variety of resources campus space utilization.

5.6 Design and Construct Only the Greenest, Most Energy Efficient New Buildings

5.6.1 LEED Green Building Rating System

The U.S. Green Building Council has done a great service by advancing the concept of green buildings through its consensus-based LEED green building rating system. LEED stands for “Leadership in Energy and Environmental Design.” A number of LEED certification systems have been developed. The one we are most concerned with here is LEED for New Construction (LEED-NC).

To be LEED certified, buildings must achieve a variety of prerequisites in these categories:

  • Sustainable Sites
  • Water Efficiency
  • Energy and Atmosphere
  • Materials and Resources
  • Indoor Environmental Quality
  • Innovation and Design Process

LEED points are earned for achieving various credits in each of these categories. Depending on the number of credit points reached, a LEED building will be either LEED Certified (26-32 points), LEED Silver (33-38 points), LEED Gold (39-51 points), or LEED Platinum(52-69 points).

Examples of campus green buildings are available from the ACUPCC and AASHE. AASHE also maintains a list of campus green building policies. The U.S. Green Building Council’s Green Campus Campaign also provides helpful resources.

5.6.2 Labs21

Laboratory buildings tend to be the most energy intensive and energy wasteful buildings on campus because of their 100% outside air ventilation systems, stringent temperature and humidity control requirements, 24/7 operation, and the energy consumed by environmental chambers, water purification systems, ovens, and other research equipment. Making new labs as energy efficient as possible is very important because their energy cost and environmental impacts are so high.

The U.S. Green Building Council has deferred to Labs21, a federal program sponsored by the U.S. Environmental Protection Agency (EPA) and Department of Energy (DOE), for establishing guidelines for green design of energy efficient laboratory buildings. Labs21 builds on the LEED green building rating system, adding prerequisites and credits pertaining to health and safety, fume hood energy use, and plug loads.

To improve lab building design, Lab21 provides technical bulletins and best practice guides on numerous subjects including:

  • Optimizing Laboratory Ventilation Rates
  • Modular Boiler Systems in Laboratory Facilities
  • Metrics and Benchmarks for Energy Efficiency in Laboratories
  • Manifolding Laboratory Exhaust Systems
  • Retro-Commissioning Laboratories for Energy Efficiency
  • Efficient Electric Lighting in Laboratories
  • Minimizing Reheat Energy Use in Laboratories
  • Water Efficiency Guide for Laboratories
  • Daylighting in Laboratories
  • Energy Recovery for Ventilation Air in Laboratories
  • On-Site Power Systems for Laboratories

5.6.3 Green Design Strategies and Measures

There are hundreds of green design strategies and measures. These general principles are among the most important:

  • Build small if at all
  • Optimize site selection in order to preserve green space and minimize transportation impacts
  • Orient building to take maximum advantage of sunlight and micro-climate
  • Use energy as efficiently as possible
  • Maximize the use of renewable energy
  • Use water as efficiently as possible
  • Minimize waste water and run-off
  • Minimize materials impacts by using green products
  • Design for a healthy indoor environment

Green design strategies, measures, products, specs, guidelines and examples can be found at these websites and others:

5.6.4 Green Design Process

The nature of the design process itself is critical. It is important to hire a design consultant with a proven track record in super-efficient green buildings that are not budget busters. Smart design can produce very green buildings with a low premium cost. The process should begin with the consultant leading a green design charrette with all stakeholders in order to establish strong low-carbon green goals for the new building.

It is important to avoid what can be called the “LEED checklist approach” wherein the LEED checklist is cherry-picked to find the cheapest, easiest way to rack up enough points to achieve a LEED rating. Institutions looking to reduce their emissions are not looking for a conventional building which just happens to have enough points to earn a plaque. Your goal should be a thoroughly sustainable design that prioritizes and maximizes energy efficiency and reliance on carbon-free solar and other renewable energy sources.

Many a good design has foundered when the inevitable building budget crisis occurs. What typically happens when the design goes over budget (and this can happen in spades when the original budget was inadequate) is that the energy conservation and sustainable design features are sacrificed first. How to prevent that? One strategy is to anticipate the building budget crisis and already identify ways to bring extra funding into the project. Maybe a wealthy alumnus or alumna will want to make a special contribution to ensure that this project breaks new ground in efficiency and the use of renewable energy. You can also argue that if a measure is on the chopping block – like for example a heat recovery system – and it could be cost effectively retrofitted through a performance contract after the building is constructed, then your school should borrow the money for this measure now and install it as part of new construction when that installation will be cheaper and easier.

It also helps to have strong backers on and off campus demanding an unwavering commitment to super energy efficient green design. While you may not get the kind of support you want from faculty (who may be distracted by the demands of teaching and research) or from professional staff (who may be muted by bureaucratic constraints), your ace in the hole are students. They are free to speak out and may be inclined to raise their voices on behalf of a super efficient building that really makes an environmental statement. Of course, it also helps to remind your administration that a failure to max out on new building energy efficiency will make it that much more difficult and costly to keep your climate goals.

5.6.5 LEED Silver is Not Good Enough!

If your campus is proceeding with new construction and is committed to achieving significant GHG emissions reductions, achieving LEED certification or a LEED Silver rating is inadequate. It would be better from an environmental and carbon-reduction perspective if your goal was LEED Gold or Platinum with a maximum number of LEED credit points that reduce the energy use and carbon footprint of the project. While many LEED credits can affect fossil fuel use and the carbon footprint of a new building, here are the credits to focus on:

Sustainable Sites (SS)

  • SS Credit 1 – Site Selection (Note: the criteria for this credit do not directly address commuting distances, but proper siting – near other development and close to public transit -- is critical for minimizing transportation-related carbon footprint)
  • SS Credit 2 – Develop Density and Community Connectivity (same comment as above)
  • SS Credit 4.1 – Alternative Transportation: Public Transportation Access

Energy and Atmosphere (EA)

  • EA Credit 1 – Optimize Energy Performance (maximize these points; up to 10 are possible – go for 8 to 10!)
  • EA Credit 2 – On-Site Renewable Energy (maximize these points; go for all 3!)
  • EA Credit 6 – Green Power

The above LEED New Construction credits are most important from the point of view of emissions reductions because they address the major elements of most campuses’ carbon footprints as revealed by GHG inventories, i.e. energy and transportation impacts.

Of course, other LEED credits can also help reduce the carbon footprint of a new building, even if those emissions reductions are not captured by the GHG inventory process. For example, reduced water use or waste water production will reduce energy use regionally and thus reduce GHG emissions (as well as produce other environmental benefits). New construction that involves reusing existing buildings or maximizing the use of certain types of green building materials and products will reduce embodied energy and thus reduce carbon emissions – albeit globally. Since our ultimate goal is saving the planet, pursuing these mitigation strategies is important even if your GHG inventory tool will not give you credit for the reductions.

5.6.6 Addressing the Cost of Green Design

Green design is generally believed to add cost to new construction projects. This premium, however, is often exaggerated. It is possible to design and construct green buildings with little or no extra cost. That becomes more challenging as the bar is raised for aggressively green, super-efficient buildings.

There are a variety of ways of eliminating or minimizing extra costs for green buildings. For example, in many regions, state or utility company incentives are available to cover costs associated with green design services or reducing the cost of specific energy efficiency and renewable energy technologies and products. Hiring an experienced green design firm can also keep costs in line. Moreover, it is possible to “tunnel through the cost barrier” and achieve big savings for less than the costs of small ones.

Tunneling through the cost-barrier, a concept popularized by the Rocky Mountain Institute, requires a whole building design approach that takes advantage of the interaction of building systems. By optimizing some systems (e.g. insulation), other systems can shrink or be eliminated (e.g. heating systems) – thus offsetting the optimization costs. For more information, see Chapter 6 of Natural Capitalism by Paul Hawken, Amory B. Lovins, and L. Hunter Lovins (1999).

When discussing the cost of green buildings, it is important to distinguish between first costs (i.e. design and construction costs) and lifecycle costs. Life cycle costs include first costs plus the costs to operate and maintain a building for its lifespan – which in the case of a campus building may be 100 years. Additional increments of first cost incurred to make a building much more energy efficient may pay for themselves many times over in energy and carbon offset savings over the life of the building. Payback, in the conventional sense, should become less important because a college or university will own and operate the buildings it constructs for such a long time horizon.

For more information on the cost of green buildings, see USGBC's list of research publications on the cost analysis of whole buildings.

5.6.7 Some Potential Achilles Heels -- Ventilation, Lighting, Windows

There are a few places where green design goals may conflict. Here are two examples – ventilation and lighting -- plus a few comments about the tricky subject of windows and green design.

Ventilation pros and cons

Care should be taken when considering LEED Environmental Quality (EQ) Credit 2 – Increased Ventilation. Higher ventilation rates typically increase building energy consumption and thus GHG emissions because they require more fan energy and can substantially increase heating and cooling loads. But increased ventilation is a good thing from an indoor environmental health perspective, right? Well, yes, but it comes at a price and its benefit can be minimal.

Building codes mandate that new buildings be designed for ventilation rates appropriate for maximum occupancy, a condition which almost never exists. Thus, it is arguable that a building whose ventilation rate is merely code compliant is already over-ventilated the vast majority of the time and that providing ventilation over and above code requirements (as envisioned by EQ Credit 2) may provide little or no health benefit while substantially increasing energy consumption and GHG emissions.

There are ways to increase ventilation while minimizing energy and GHG penalties -- for example, by installing heat recovery or using variable speed drives and air quality sensors to modulate air flows so that air volume (measured in terms of cfm or cubic feet of outside air per minute) is appropriate to actual occupancy. These technologies are steps in the right direction and should be used extensively but the net effect of increased ventilation is almost always greater energy use and thus a greater carbon footprint.

Direct and Indirect Lighting

Green designs tend to use indirect lighting which eliminates glare and lighting hot spots and may produce more comfortable lighting and thus increase productivity – all important pluses. However, lighting fixtures and designs of this type may be more expensive and less energy efficient in providing illumination on the work surface. As a result indirect lighting may drive material and energy costs up and with them the carbon footprint of building lighting systems.

There are number of ways to cope with the potential downside of indirect lighting. The first is to avoid indirect lighting and instead use conventional direct lighting systems, i.e. recessed troffers. These provide good light and, especially if equipped with high efficiency lenses, can be very efficient.

Another approach is to use indirect lighting fixtures sparingly or to provide a low level of background lighting and then rely on efficient task lighting to put light on the work surface. Note that overall lower foot-candle levels may be acceptable not only because of the availability of task lighting but also because the light quality of new fluorescent lamps (as measured by CRI or color rendering index) is far superior to older fluorescent bulbs and is perceived by the human eye as brighter than foot-candle measurements would lead one to expect. It makes sense to take advantage of this and thus to design for lower foot-candle levels.

Instead of prescribing in detail the kinds of lighting design and fixtures you want, you can give more latitude and require the designer to meet an aggressive performance standard. For example, you could require a building-wide average lighting wattage density of no more than 0.75 – 1.0 watt per square foot – erring on the low side – and of course taking into account the benefits of daylighting.

Sensible, Efficient Use of Glass and Windows

It is common for new buildings, irrespective of LEED rating, to have lots of glass. Large windows, glass walls, and exciting atria can produce beautiful daylit spaces. But glass, unless properly specified and judiciously used, can also have a large energy and GHG penalty.

Daylighting designs should be computer-modeled to ensure that the electric lighting savings they produce are much greater than the additional heating or cooling costs they impose. Also, as obvious as this is, it deserves re-stating: not all windows are equal in their performance. There is a tendency to think that if windows are Energy Star-compliant that is sufficient, but the Energy Star standard for windows is outdated and profoundly inadequate.

Genuine high performance windows should be selected – and in cold winter weather climates that means triple glazed windows with double low-e coatings with center of glass U-values of 0.15 or better. Where south-facing windows are serving a passive solar heating function during the heating season, they should be specified to have as high a Solar Heat Gain Coefficient as possible -- otherwise they will block sunlight and substantially reduce insolation or solar gain. Architectural shading is required for south-facing windows to block direct summer sun entering windows, exacerbating cooling loads.

If you opt for operable windows, an indoor environmental quality benefit, a system should be established so that occupants know when they can open windows and when they need to be shut. Such a system would evaluate the enthalpy or heat content of indoor vs. outdoor air to determine when there is an energy benefit or penalty associated with open windows. Windows can be interlocked with HVAC systems so that heating and cooling is shut off when windows are open.

5.6.8 Green Building Resources and Under-Resourced Higher Education Institutions

The Campus Green Builder is an initiative by the Advancing Green Building program at Second Nature. The site was launched on November 2nd 2009 and is a repertoire of resources for those with an interest in green building development either as a hobby or out of necessity.

Community colleges, Historically Black Colleges and Universities, tribal colleges, Hispanic-serving institutions and other under-resourced institutions are often at a disadvantage due to the lack of funds, lack of expertise and lack of exposure to readily available resources. With technical, financial, educational, various other resources and discounted memberships, Campus Green Builder aims to provide its audience with a central location where they can start acquiring the knowledge and tools to become familiar with sustainable development.

Though relevant to higher education as a whole, Campus Green Builder is particularly beneficial for under-resourced institutions considering building green on their campus but do not know where to start and are not aware of the assistance available in their regions and states. For example, under the financial section of the site an individual in Alabama can sort for state funding and find out that “Tennessee Valley Authority (TVA) offers a production-based incentive program for the installation of solar photovoltaics (PV), wind, low-impact hydropower, and biomass to customers of the Tennessee Valley.”

The Campus Green Builder provides hundreds of links to green building-related web sites, directories of experts, and resources for training and funding opportunities. This web portal is also excellent for accessing green building related news, events and networking resources. Finding an expert in your region to discuss your plans or assess green building potential on your campus is now easier than before by going to the many green expert directories on the Campus Green Builder website. The hope is that this web portal will be the stepping stone, a starting point in other words, to explore various opportunities through not only resources but also case studies of under-resourced institutions and networking with other higher education individuals.

Did you know the Los Angeles Community College District is taking nine of its colleges off the grid? How are they planning to do this? Visit the East L.A. College Case Study on the Campus Green Builder to find out!

5.7 Transportation Solutions

For ACUPCC institutions, climate neutrality is defined to include reducing, eliminating, or offsetting the GHG emissions associated with the operation of fleet vehicles; student, faculty and staff commuting; and business air travel. Even schools which have not made a total commitment to addressing these emissions will be interested in reducing them and other environmental, social, and public health impacts associated with these campus-related activities. Of the three, commuting generally involves the largest carbon footprint. It poses a huge challenge.

The Transportation section of AASHE's Resource Center has an abundance of resources on transportation solutions including an extensive listing of campus alternative transportation websites. The Transportation Demand Management Encyclopedia and the Transportation Demand Management and Telework Clearinghouse are also helpful resources.

5.7.1 Fleet Vehicles and Campus Buses

Facilities managers can address GHG emissions associated with fleet vehicles in a variety of ways which include:

  • Buying only the most fuel efficient vehicles
  • Choosing the most fuel efficient vehicle appropriate to the task
  • Using vehicles which run on alternative fuels like electricity, biodiesel or compressed natural gas
  • Implementing policies to reduce vehicle miles driven
  • Implementing a no-idling policy

The latter is an issue on campuses where some facilities staff may leave their vehicles running much of the day during colder winter months to keep them warm and comfortable even though they are only driving them a few minutes a day. You can see whether this is happening by direct observation or by analyzing data on vehicle mileage and gas fill-ups (if your facilities unit keeps this information). If winter mpg drops to single digits, it may be due to excessive idling.

Campuses may be in the habit of buying fuel inefficient vehicles for a variety of reasons. For example, it may be assumed, mistakenly, that all facilities staff need to drive around in trucks or four wheel drive vehicles. Some state-affiliated schools may find that state contracts make it cheaper to buy larger fuel inefficient vehicles. These barriers and others to buying highly fuel efficient vehicles need to be addressed and overcome.

Electric vehicles, even those powered by a regional electric grid that is not especially clean, tend to be less carbon-intensive than standard gasoline-powered vehicles. Small GEM type electrics are better suited to warmer climates or to summer-only use in campuses with cold winters. Facilities staff could also ride bicycles to meetings on other parts of the campus if the dress code is relaxed. Wearing informal clothing also makes it possible to air condition less – another benefit to your “low carbon bottom-line.”

Using biodiesel for fleet vehicles raises some issues. Remember that B20 biodiesel fuel is only 20% biodiesel and 80% conventional diesel fuel, and even the biodiesel portion is probably not fully carbon-free because fossil fuels may be consumed in its manufacture or shipping. Switching to biodiesel blends which are richer in biodiesel is desirable though can be problematic in colder climates due to the increased viscosity of biodiesel as the temperature drops. One solution might be to use B100 (100% biodiesel) during the summer months and switch back to B20 during colder weather.

Biodiesel is a good fit for campus buses as well as larger facilities vehicles. While most college and university facilities units will not be interested in manufacturing their own biodiesel (since it is an extra task and they are probably already short-staffed), some have been approached by students and faculty interested in seeing campus food service waste fryer grease converted to biodiesel to run campus buses or fleet vehicles. Such an arrangement would have significant educational value. Conceivably, a campus-based biodiesel production facility could be designed, operated, and monitored by students under faculty and facilities supervision.

Conversion of fleet vehicles to compressed natural gas generally requires the installation of a CNG refueling station on or very near campus. This can be an expensive undertaking – though might be subsidized by state energy offices that are promoting alternatively fueled vehicles or by local natural gas utilities interested in selling more natural gas. Duel-fuel CNG vehicles can be purchased or existing gasoline-powered vehicles can be kit-converted to CNG. Campus buses also can be CNG powered. If campus bussing is provided on contract by an outside vendor, then new contract language specifying an alternative fuel will be required next time this service goes out to bid.

Operating a car, truck or bus on CNG will reduce GHG emissions by about 25% compared to gasoline operation. There can be substantial cost savings associated with using CNG vehicles (in comparison to gasoline) but this benefit vanishes when gasoline prices are low and natural gas prices are high. Assuming gasoline and CNG vehicles operate at roughly the same efficiency, $2 a gallon gasoline roughly equals $7/MCF natural gas.

5.7.2 Commuting

The larger transportation problem is commuting. At most colleges and universities, commuters dominate and typically arrive and depart from campus in single occupancy vehicles – many with poor fuel economy. Commuting by students, faculty and staff may add up to many millions of miles of driving per year at larger schools – and thus represent a substantial part of the campus carbon footprint.

Here are some strategies for reducing commuting and its GHG impact:

Raise awareness of transportation alternatives

  • Create an effective transportation and climate change awareness program
    • Team up with your campus transportation office to create this program
    • Include messaging with billing statements for campus parking permits
    • Highlight the seriousness of climate change, the carbon footprint of commuting, strategies commuters can use to reduce GHG emissions, and your school’s climate goals
    • Provide alternatives to single car/truck commuting
    • Encourage the use of high efficiency vehicles when car/truck commuting is unavoidable
    • Let your audience know about incentives for using alternatives

Increase use of public transit by students, faculty and staff

  • Better publicize existing public transit options
  • Work with your regional transit authority to add public transit routes
  • Increase the frequency of public transit service
  • Extend late night public transit service
  • Provide free public transit passes or subsidize public transit fare
  • Move suburban or rural campuses to downtown urban locations to facilitate the use of public transit! (OK, this is probably not practical but it highlights the potential very large and difficult-to-ever-remedy carbon footprints associated with campuses built in locations not served or not easily served by public transit)

Increase carpooling

  • Establish rideshare program to safely match interested drivers and carpool riders
  • Provide incentives for carpooling, e.g. priority parking, reduced parking fees, etc.
  • Provide emergency ride home service for carpoolers

**Increase bicycling **

  • Make campus bicycle-friendly
    • Establish bicycle-friendly campus policies that actively encourage and reward bicycling and don’t penalize it (an example of the latter would be a policy that forbids students from locking their bikes to light poles or trees – it may be hard to believe but such policies exist!)
    • Create an extensive and effective network of campus bike paths
    • Address campus bicycling safety issues
    • Install or increase the number of secure bike racks on campus
    • Provide weather-protected bike racks and bicycle lockers
    • Establish an on-campus bicycle repair shop and free air pump
    • Equip buses with bike racks, and instruct riders how to use them
    • Create or join local bicycle sharing programs
  • Make bicycle commuting more practical
    • Work with local communities to improve and expand the network of local bike paths and bicycling safety
    • Create safe bicycling commuter routes to campus through the surrounding community, especially from areas with a high density of off-campus student housing
    • Provide shower facilities for bicycle commuters
    • Relax formal or informal dress codes to accommodate bicycle commuters

Reduce on-campus driving

  • Make campus more bicycle and pedestrian friendly
  • Improve scheduling and routes of campus buses
  • Locate new buildings to encourage walking and bicycling
  • Minimize or don’t provide additional parking for new buildings
  • Consider banning cars for on-campus resident freshman and other students

Reduce the need to single occupancy vehicle (SOV) commute

  • Move electrons not people and vehicles
    • Increase telecommuting
    • Increase distance learning
  • Build more on-campus housing (which ironically will reduce your campus’ commuter carbon footprint while increasing your campus housing carbon footprint)
  • Work to improve neighborhood safety and privately owned off-campus housing near campus in order to make it more likely that students living off campus will chose to live near campus
  • De-bundle transportation fees that package parking, bus and transportation fees all together so faculty, staff and students who do not bring a car to campus can pay less
  • Pay employees not to drive
  • Provide shuttle service to nearby off campus student housing developments and neighborhoods
  • Create employee van pools
  • Allow compressed work weeks, i.e. 4 ten-hour days/wk instead of 5 eight-hour days/wk to eliminate one commute per week
  • Explore alternative course scheduling to reduce the number of days per week most students need to come to campus

**Re-focus campus parking policy **

  • Stop building new parking lots and ramps
  • Redirect money which would be spent on new parking lots or ramps to “transportation demand management” measures that reduce commuting and save money compared to expanding on-campus parking
  • Begin charging for or increase the cost of on-campus parking

Reduce the carbon-intensity of vehicles used for commuting

  • Encourage the purchase and use of highly fuel efficient personal vehicles through awareness and incentive programs (an example of the latter would be reducing parking fees for commuters who drive more fuel efficient vehicles)
  • Establish a program to allow or require students, faculty and staff to pay for their own commuting carbon offsets

Other Strategies

  • Prioritize energy efficient low carbon transportation planning in campus master plans
  • Create a campus transportation committee charged with responsibility for shrinking the carbon footprint of campus commuting
  • Establish or contract with car-sharing programs/companies to make it easier for people to avoid car ownership (and thus drive less)
  • Contact elected officials and tell them we need a carbon tax! (This may seen farfetched but it’s here to illustrate an important point, namely, that we need larger policy changes to help us significantly reduce our carbon footprints. Colleges and universities typically participate in the political process when it is in their interest to do so. This is such a case.)

5.7.3 Air Travel

Addressing the business air travel component of your school’s carbon footprint involves setting up a mechanism to track official campus business air travel, calculating the GHG emissions associated with those flights, and then mitigating or offsetting the emissions.

The Clean Air-Cool Planet Campus Carbon Calculator is able to calculate and include air travel-related emissions in your campus GHG emissions inventory.

The simplest option you have for mitigating these emissions is encouraging less air travel. Providing easy access to teleconferencing would help make it easier and far cheaper for faculty and staff to connect with colleagues electronically. A more controversial step would be to mandate less travel, though with budget cuts affecting schools nationwide there simply may be less money allowed for air travel.

5.8 Other GHG Mitigation Strategies

5.8.1 Waste Disposal

It may not be intuitive, but waste disposal and waste management practices impact our carbon footprints. A big part of the reason is that throwing things away -- just like every other activity – involves energy consumption and that typically means burning fossil fuels. Also, if garbage and trash are burned, there are additional releases of carbon dioxide – though some of those emissions can be mitigated or offset if the waste is burned in a waste-to-energy plant because such a plant displaces fossil fuel combustion. If the end point for your campus garbage and trash is a landfill, methane will be produced through decomposition. On a mass basis, methane has around 20 times the global warming potential of carbon dioxide – so landfills can have a substantial climate change impact. This climate impact of landfills is mitigated if the methane is captured and either “flared” (burned in the open atmosphere – releasing water vapor and carbon dioxide) or burned in a boiler or power generating unit to produce useful heat or electricity that displaces the fossil fuels that would otherwise be used to produce that heat or power. Thus, while the devil may be in the details, it is clear that reducing waste disposal can be an effective GHG mitigation strategy.

Campuses can cut waste through waste reduction programs (buy and use less, reuse, etc.) and by improved recycling and composting programs. Recycling keeps waste out of both the incinerator and landfill. It also contributes to the manufacture of new products made of recycled materials which are more energy efficient to make and, thus, are responsible for less GHG emissions. Composting prevents organic waste (kitchen produce waste plus landscaping trimmings) from being needlessly transported to the landfill and turns these materials into a useful product for keeping the campus green.

Participating in the annual Recyclemania competition is a great way to improve and boost recycling on your campus.

CA-CP’s Campus Carbon Calculator will calculate the emissions associated with campus waste volumes, how that waste is disposed of, and the amount of recycling your school is doing. The Calculator will not, however, calculate the GHG emissions benefit associated with “closing the loop,” i.e. using recovered materials to produce products with recycled content – though that climate protection benefit is real nonetheless.

AASHE maintains a list of campus websites on waste reduction and recycling and a list of policies on campus waste minimization and recycling.

5.8.2 Embodied GHG Emissions in Products

As just pointed out, not all campus GHG emitting activities are captured by greenhouse gas emissions inventory tools. However, since our ultimate goal is to address the problem of climate change in as comprehensive and effective a way possible, it is important that all GHG emissions sources be identified and as many as possible mitigated irrespective of whether we can quantify or take credit for the benefits.

Since nearly everything that is purchased contains embodied fossil fuel and thus GHG emissions, purchasing policies and practices are of critical importance even though their related emissions and mitigations fall in the categories of “can’t be quantified” and “can’t be used for carbon credit.” To reduce these GHG emissions, colleges and universities can:

  • Implement purchasing policies and practices that, well, discourage purchasing!
    • Establish reuse programs
    • Swap shops or swap websites that facilitate the reuse of materials between campus and institution offices
    • Policies that make it easier for schools to give still-useful unwanted items away
    • Programs that allow students to donated unwanted clothing and other items on end-of-the-semester move out days
  • Buy products which contain high levels of recycled content
  • Buy locally produced products

Another way of addressing this issue would be to buy carbon neutral products. The market is just beginning to develop. The Carbon Reduction Institute has developed a certification program for carbon neutral companies and products.

AASHE maintains a list of campus green purchasing websites. Two additional resources are the Responsible Purchasing Network and Buying for the Future: Contract Management and the Environmental Challenge by Kevin Lyons (2000).

5.8.3 Food Service and Food Choices

Another area of campus activity that can have a substantial GHG impact (though not quantified by your GHG emissions inventory) is campus food service and food choices. Mitigation strategies here include:

  • Increase purchases of locally produced food
  • Prepare food in more energy efficient kitchens
  • Reduce waste, recycle and compost
  • Encourage eating lower on the food chain, i.e. less meat

There are many reasons to buy locally produced food including benefits to the local farmers and the regional economy and establishing a connection between the food we eat and where and how it is produced.

Kitchen cooking equipment can be notoriously inefficient. Think industrialize-size toasters that are left on whenever the foot service outlets are open – probably consuming enough electricity and producing enough waste heat to heat an average home. Think pizza ovens left open – constantly venting heat. Kitchens also have ventilated cooking hoods over stoves that pull a lot of heated air out of the building (and may or may not be equipped with heat recovery to reduce that waste). If the cooking occurs in campus buildings, its carbon footprint will be captured by your GHG inventory.

Composting pre- and post-consumer food waste reduces solid waste disposal, produces soil amendments for campus gardens, and can serve an educational purpose – especially if students are involved in setting up the program, collecting the compostables, and managing the compost pile.

In 2007 the United Nations Food and Agricultural Organization released a comprehensive report entitled Livestock’s Long Shadow which documents the global environmental impacts of meat production. One eye-opening finding of this report is that livestock production is responsible for 18% of annual global greenhouse emissions – a larger slice of the “emissions pie” than the transportation sector. Thus, food choices and diet deserve at least as much consideration as transportation choices, and eating less meat becomes an important GHG mitigation strategy. However, some sensitivity is required when encouraging people to eat less meat or try a vegetarian diet because in our society food choice is considered to be a more private matter than, say, vehicle or light bulb choice. But whether we like it or not, the disproportionately large carbon footprint of a hamburger is just one more inconvenient truth about climate change. It’s important that we educate about all the behaviors and activities that contribute to global climate change and encourage people to take action to reduce their climate impact.

Clean Air-Cool Planet is in the process of developing a module for its Campus Carbon Calculator that will calculate the carbon footprint of campus food service, highlighting the need to address diet as well as operations.

5.9 Carbon Offsets

5.9.1 The Role of Carbon Offsets

Internal GHG emissions reductions must be the first priority of colleges and universities committed to reducing their carbon footprint. However, despite our best efforts, in the short to mid-term, the majority of colleges and universities will be only partially successful in eliminating their GHG emissions. Remaining GHG emissions can be offset by purchasing financial instruments that help pay for projects which reduce GHG emissions elsewhere, i.e. not on our campuses, or by using our own resources to create these kinds of projects in the wider community. In addition to taking us those last steps in carbon reduction, carbon offsets may be used to meet interim CAP emissions reduction targets when good faith internal reduction efforts fall short. It’s a simple concept. But the devil’s in the details.

5.9.2 Projects that Can Create Carbon Offsets

Carbon offsets can be produced in a number of ways. For example, energy conservation and efficiency, fuel switching, renewable energy, and carbon capture and storage projects can prevent or avoid the release of GHG emissions into the atmosphere – and hence may produce legitimate carbon offsets.

Reforestation projects can remove carbon from the atmosphere and sequester it in biomass – at least temporarily -- and hence may count as valid carbon offsets.

Capturing the methane produced at landfills and flaring it (burning it in the atmosphere to convert it to less harmful carbon dioxide) can decrease the GHG emissions impact of landfills -- and hence may produce valid carbon offsets. On a mass basis, methane is a much more powerful GHG than carbon dioxide; that’s why it is advantageous from a climate protection point of view to flare methane even though the end result is an atmospheric release of carbon dioxide. It is even better – and more productive in terms of carbon offsetting ¬– to burn the landfill-harvested methane in a boiler or turbine that generates electricity and useful heat, thus displacing the fossil fuels which would have otherwise been burned for those purposes. Such a combination strategy would increase the offset value.

The destruction of industrial refrigerants (CFCs and HCFCs, for example) and other climate-harming gases is also beneficial from a climate protection perspective – and thus another means of producing “carbon” offsets. In all cases, however, certain conditions must be met before these kinds of projects can be regarded as producing legitimate carbon offsets

5.9.3 Defining High Quality Carbon Offsets

At present, the carbon offset market is in its infancy and buying offsets might seem a little like buying “a pig in a poke.” If that phrase is unfamiliar, it means (as per the Wikipedia): “to make a risky purchase without inspecting the item beforehand.” Another way of saying it would be “caveat emptor” (let the buyer beware). There is a great deal of skepticism about carbon offsets. For various reasons carbon offsets have been perceived as:

• Producing little or no real GHG emissions reduction benefit
• A way of excusing bad behavior or buying one’s way out
• An example of green-washing

But with the right guarantees and third party certification carbon offsets can produce real emissions reductions, and in that case those who are responsible for creating or financing these reductions have the right to take credit for them.

The ACUPCC Voluntary Carbon Offset Protocol provides guidance for purchasing valid, high quality offsets. According to the Protocol, these offsets must be:

  • Real
  • Additional
  • Transparent
  • Measurable
  • Permanent
  • Verifiable
  • Synchronous
  • Account for leakage
  • Registered
  • Not double counted
  • Retired

All of these attributes have technical meanings which are explained in the Protocol.
While all of them are important, the concept of “additionality” deserves highlighting. Quality offsets must produce GHG emissions reduction “in addition” to what would have occurred anyway or as a matter of “business as usual.” Carbon offsets will be viewed skeptically until the carbon offset market identifies convincing ways to demonstrate additionality.

A confusing offset condition is that of permanence. This criteria does not require that the carbon offset be permanent in the sense of producing carbon reductions year after year forever. Quite the contrary since it is understood that the projects which produce carbon reduction will not last forever and thus carbon offsets are time-bounded instruments. For example, your school’s purchase of carbon offsets may make it possible for a wind turbine to be erected and operated – however, that turbine will only last for a discrete number of years and your claim to be offsetting carbon through your investment in that turbine lasts only as long as the turbine lasts (or for whatever duration specified by your offset).

The permanence criteria applies primarily to biological sequestration. Imagine that you have purchased carbon offsets based on funding a reforestation project. If the trees your offset money helped plant and care for are eventually cut down, that act not only ends any future carbon sequestration by those trees but may also undo and releases back into the atmosphere the carbon which was biologically sequestered by those trees in previous years – thus undoing the offsets that you previously counted. The “permanence” requirement is to prevent that circumstance from occurring. It underscores the difficulty of using and counting biological carbon sequestration.

5.9.4 Buying or Creating Carbon Offsets

Schools can purchase offsets on retail and wholesale markets or create them by developing projects which result in emissions reductions. The latter option allows colleges and universities to work with groups and individuals in their own communities or in remote locations to create clean energy or energy saving projects. The Guidelines accompanying the ACUPCC Voluntary Carbon Offset Protocol provide helpful qualifying criteria for these projects.

When should you begin purchasing carbon offsets? Since there is a cost associated with carbon offsets, the natural tendency would be to delay buying offsets as long as possible. Delay would also allow the market to mature and become more reliable before jumping in.

A logical approach to timing the purchase of carbon offsets would be to buy them incrementally and in appropriate amounts to help meet aggressive interim GHG emissions targets in your climate action plan or when interim targets are unexpectedly not fully met because of insufficient internal emissions reduction efforts.

If you are planning to create your own carbon offsets by sponsoring clean energy projects in your own community or state, then work on these projects should begin much earlier than you expect to be able to claim the offsets. Of course, even if you are planning to simply purchase offsets from the market, research and planning in advance of anticipated purchase dates is essential.

For more information about carbon offsets, please see the [FAQ section][2] of the ACUPCC Voluntary Carbon Offset Protocol. Scroll down and see links to various recommended resources on carbon offsets. Also see Clean Air Cool Planet's Consumer's Guide to Retail Carbon Offset Providers -- though this report is somewhat dated (2006).

5.9.5 Campus Forest and Lands as Carbon Offsets?

The search for cost-effective ways of off-setting campus carbon emissions may lead some colleges and universities to consider counting the carbon which campus biomass removes from the atmosphere and sequesters annually. Campuses with large forested land areas would seem to have a large offset potential. However, there is a big difference between forests which sequester carbon (they all do unless they stop growing, are cut, or burned) and forests whose carbon sequestration can count as a legitimate carbon offset. In order for campus biological carbon sequestration to count as a carbon offset that sequestration must be “additional” to what would have occurred anyway. In other words, it would be misleading to count the carbon which is sequestered in already existing forest land as an offset and subtract that carbon from your campus GHG emissions total. However, carbon sequestration of newly planted forest could be counted as an offset as could any additional carbon uptake associated with changes in forest management.

The issue of “permanence” also arises when we consider biological carbon sequestration. See section above for more details.

While there are legitimate barriers to counting campus biomass carbon sequestration as carbon offsets in your GHG inventory or taking credit for them in your CAP, it still makes sense to protect campus green space and forested land – for all the traditional environmental and social reasons and because of climate change. When trees are cut down, they are lost as a carbon sink. Moreover, even if the carbon sequestration associated with campus biomass cannot be counted as an offset, it is still OK to state in your GHG inventory summary or CAP that your campus has X amount of forested land and those trees are sequestering Y amount of carbon annually. Publicizing that kind of information may help campus environmental advocates protect campus greenspace when plans are unveiled to start cutting trees on campus to clear land for that next campus research building, dormitory or apartment complex.

For more information on this complicated issue, see page 42 of the ACUPCC’s Investing in Carbon Offsets: Guidelines for ACUPCC Institutions. Also see the Greenhouse Gas Protocol’s Land Use, Land-Use Change, and Forestry Guidance for GHG Project Accounting.

6. Project Evaluation and Ranking

Project evaluation and ranking is one of the one important parts of a CAP. This section discusses techniques and methods for undertaking these tasks. Also see the sections on Evaluating Energy Conservation Projects, Avoid the Short Payback Trap, and Revolving Funds.

6.1 Calculating Project GHG Emissions Reductions

While you can use carbon emissions calculators to determine carbon emission reductions associated with specific projects, these calculations are easy to do and can also be done with a simple calculator or a spreadsheet of your own design.

To perform these calculations for energy conservation or renewable energy projects, the first step is figuring out how much energy they save. Well known engineering formulas can be used to calculate energy savings. Then, apply the GHG conversion factors to the amount of energy saved by various fuel types to produce the GHG emissions reductions they achieve as measured in kg or metric tons of CO2 equivalent.

To convert purchased electricity savings into GHG emissions reductions, it is necessary to identify the conversion factor appropriate to your regional grid since the mix of power generation types and carbon-intensity of electricity generation differs from region to region. This kilowatt hour-to-CO2 conversion factor can be obtained by consulting the eGrid website.

To better understand how to calculate the GHG emissions associated with the consumption of various fuel and electricity, see the U.S. Environmental Protection Agency’s Clean Energy Calculations and References webpage. This resource contains numerous sample calculations.

6.2 Decision-Making Criteria

As the previous section of this climate action planning guide makes clear, there are many types of action your campus can take to reduce its carbon footprint. One of the most daunting tasks involved in assembling your CAP is evaluating, ranking, and deciding when to do what. A comprehensive list of criteria for evaluating, prioritizing, and selecting projects might look like this:

Proposed projects can be compared on the basis of any or all of these factors. Typically, a CAP will list prospective projects on a chart noting:

Some of the above decision-making criteria cannot easily be quantified. But comparative information could be captured in a comprehensive matrix which could rank projects on as many of those criteria as possible. Conceivably, most or all of the above decision-making factors could be considered in a comprehensive lifecycle analysis of prospective carbon mitigation projects and measures. Note that there is an in-depth discussion of payback and lifecycle cost analysis for energy conservation projects in this manual.

6.3 Carbon Reduction Efficacy

Let’s take a closer look at the cost of a project in relation to its ability to produce GHG emissions reductions, i.e. cost per MTCO2e. This type of evaluation – which can be called carbon reduction efficacy – is important because it shows which projects produce the biggest bang for the buck in terms of carbon reduction.

The illustration below graphically shows how a $/MTCO2e analysis of projects can be presented.

Image courtesy of Clean Air-Cool Planet

The bars depict and compare four theoretical carbon reduction projects or measures. The two on the left side of the chart -- represented by bars that descend below the zero line -- have negative net present values per ton of carbon dioxide mitigated and thus produce overall dollar savings. The projects on the right side of the graph -- represented by bars that extend over the zero line -- have positive net present values and do not produce savings in amounts greater than their costs. The projects are arrayed from left to right in order of most attractive to least attractive in terms of their carbon reduction efficacy or cost/offset ratio. The width of each measure shows the overall GHG reduction that results from the measure.

This type of analysis and chart-making can be accomplished automatically through the use of the Solutions Module in Version 6 of the Clean Air-Cool Planet Campus Carbon Calculator -- though the Calculator can only undertake these operations after you enter specific project data.

The next graph is from Charting a Path to Greenhouse Gas Reductions by Sam Hummel, former Environmental Sustainability Coordinator at Duke University. It shows specific projects under consideration at Duke during a study in 2005. Several are identified by letter in the key just below the graph. Purchasing new high capacity buses (measure A) would provide Duke with dollar savings at an attractive carbon reduction return per dollar invested but not much overall carbon reduction. In contrast, reducing coal burning in Duke’s power plant by burning more natural gas (measure R) costs Duke money and has a long payback, but will produce a large carbon emissions reduction.

Reprinted from Charting a Path to Greenhouse Gas Reductions with permission of Duke University.

Key for some measures shown on graph above:

A - Purchase high capacity buses
H - Co-fire biomass in steam plant
L - Purchase wind power
R - Natural Gas Blend in Steam Plant
S - Install solar electric system

It is clear that carbon mitigation efficacy is an important decision-making criteria when evaluating and prioritizing carbon reduction projects and measures. However, as the discussion in the Energy Conservation and Efficiency section should make clear, many other considerations may be equally important.
 

7. Setting Emissions Targets and Measuring Progress

7.1 Your GHG Emissions Reduction Goals

ACUPCC institutions have committed to achieving climate neutrality "as soon as possible". In their CAPs, ACUPCC schools need to identify a date for achieving climate neutrality as well as dates for achieving interim emissions reduction goals.

Colleges and universities not participating in the ACUPCC need to define their GHG emissions goals not only in terms of emissions reductions targets and dates for achieving them but also in terms of the categories of GHG emissions to be reduced. Conceivably emissions reduction goals can be established separately for Scope 1, 2, and 3 categories of GHG emissions. ACUPCC signatories may also choose to state interim targets by emissions scope type.

In all cases, campus GHG emissions reduction goals should be challenging and they should encourage colleges and universities to demonstrate real leadership by committing to significant reductions and achieving the lion’s share of them very quickly. Leading climatologists like NASA’s Jim Hansen have said that the window for action is closing and that if we – as a species -- do not make significant progress reversing GHG emissions trends within the next ten years, it will be too late to avoid the worst consequences of climate change. Thus, it is time for action. Campus climate action plans must be deemed failures if they do not produce the rapid response that is needed.

What is a reasonable timeframe for ACUPCC schools to achieve climate neutrality? Given Hansen’s plea, ten years or less seems right in order to demonstrate the kind of leadership that is needed now. That period is long enough to do big things yet short enough to be well within the careers of many or most of your CAP key players – maybe even your president. If your climate neutrality dates are pushed too far into the future, they will seem abstract and may undermine serious action now – when that action is so important. Your GHG emissions targets should create some tension and pressure to accelerate action.

While comparisons with other institutions are not always appropriate or helpful, it's worth examining GHG emissions reduction goals established by other colleges and universities. AASHE maintains a list of campus climate commitments, and the commitments of ACUPCC signatories will be posted on the ACUPCC's online reporting system.

7.2 Using Forecasting and Backcasting Methods to Develop Scenarios

In establishing GHG emissions reduction goals and targets your CAP team may want to use both forecasting and back-casting methods.

Forecasting involves examining future options to reduce GHG emissions and determining from that analysis how soon you can reach them. A forecasting process involves identifying likely or possible GHG emissions strategies and projects, evaluating and prioritizing them, placing them on a timeline for implementation, and then calculating how much GHG emissions reductions these projects can achieve in successive years.

Typically, forecasting involves creating a number of scenarios with increasing levels of commitment. One scenario might be “easily do-able.” Another, “more challenging.” And a third representing an “all-out effort.” More creative or entertaining language can be developed for these scenarios, such as the “No Brainer,” “No Regrets,” and “Take No Prisoners” scenarios from the Oberlin College Climate Neutral by 2020 report prepared in 2002 by Rocky Mountain Institute. Your planning team develops the scenarios and determines what projects and measures would be required to accomplish them.

Back-casting operates in the reverse direction; it projects backwards. With back-casting your CAP team would hypothetically establish various dates for achieving your carbon emissions goals and then work backwards from each to see what would have to be done during the intervening years to achieve that level of reduction.

7.3 Finalizing Your GHG Emissions Reduction Proposal

Once scenarios are internally defined and analyzed, your CAP team should seek public comment from the campus community perhaps through a series of presentations or town meetings. The scenarios with accompanying GHG reduction trajectories could also be presented on your CAP website with an easy mechanism provided to solicit electronic comments.

Comments received through these feedback mechanisms need to be addressed by your CAP team. This process may result in the modification or abandonment of certain scenarios and targets.

Once feedback is considered, your CAP team may wish to weigh all options again and then either go back out to the campus community for more comments or move directly to preparing a proposal for campus leadership. That proposal might be a specific scenario to achieve “X” reduction by “Y” date. Or it might be a prioritized list of different scenarios with different targets In any event, your president and campus leadership should not be surprised by your CAP team’s submittal. The CAP process can only work if your president and key campus leaders are involved and on-board each step of the way.

7.4 Additional CAP Components and Tools

**7.4.1 Establishing Your Glide Path – Downward Trajectories and Interim Targets **

Getting to your carbon goal will be an incremental process involving a multitude of steps, measures, and projects. To help keep you on track, interim goals with accompanying dates should be established against which you can measure progress and see whether the trajectory you’re on matches the one you should be on. To be relevant to the climate change danger we face, your glide path should be downward pointing on as steep a trajectory as possible.

Detailed GHG emissions reduction scenarios produce downward sloping emissions trajectories. These can be graphed to facilitate comparisons. This graph below is from UC Berkeley Climate Action Partnership: Feasibility Study 2006- 2007 Final Report. It shows a business as usual trajectory of ever increasing emissions plus a number of other trajectories based on different targets or scenarios. This graph compares a UC Berkeley 2020 trajectory (blue line) and target with a State of California trajectory and target (green line). It shows that in the short term neither trajectory is as aggressive as that crated by the Kyoto Protocol 2012 target (purple line).

Reprinted from UC Berkeley Climate Action Partnership Feasibility Study 2006- 2007 with permission of UC Berkeley.

Once a given climate action plan and emissions reduction scenario is approved by your president and administration, its trajectory can be used to identify interim targets. Those interim targets become part of your CAP.

What happens if internal GHG emission reduction efforts are insufficient to meet an established CAP interim target? Your school has a number of options. It could:

It’s important that colleges and universities committed to addressing climate change make good faith efforts to meet interim targets on the way to achieving their long range GHG emissions reduction goals despite bumps in the road. Of course, there may be pleasant surprises as well that enable institutions to meet interim-targets ahead of time and continue on an accelerated timetable.

7.4.2 Relative Measures of Progress

In addition to absolute reductions in GHG emissions, there are others ways to show progress or the lack of it. For this purpose of interim goals and targets you could also use normalized or relative data such as:

In all cases, you would hope these indices trend steadily in a downward direction.

Normalized or relative measures can be particularly helpful on campuses that are in an expansion (or contraction) mode. If your student body is growing or your school is constructing new buildings, normalized measures like GHG emissions per student or per square foot may allow you to show progress even when your overall GHG emissions are not shrinking very quickly or at all. Just remember that our collective overall human species goal is to actually reduce GHG emissions in absolute terms. That’s what we must strive for.

Note that when calculating GHG emissions per annual heating or cooling degree days, it is important that only the GHG emissions caused by campus heating or cooling energy consumption be adjusted. Non-heating and non-cooling-related GHG emissions caused by “baseload” energy use, e.g. lights, motors, and plug loads, must be excluded – or else the data produced by this kind of analysis will be skewed and possibly meaningless. Clean Air-Cool Planet is attempting to modify its Campus Carbon Calculator to take this into account.

7.4.3 GHG Mitigation Wedges

In 2004, S. Pacala and R. Socolow published an article in *Science *magazine entitled, “Stabilization Wedges: Solving the Climate Problem for the Next Fifty Years with Current Technologies.” This article popularized the concept of emissions reduction wedges. In their article, Pacala and Socolow proposed using seven wedges, each representing a GHG emissions reduction strategy capable of eventually reducing U.S. GHG emissions by 1 gigaton of CO2e per year by 2054. Pacala and Socolow identified 15 technologically feasible wedges capable of achieving that kind of performance. Their discussion assumed an initial “business as usual” upward trajectory for U.S. fossil fuel energy use and GHG emissions. Pacala and Socolow’s goal was merely to show how implementing seven wedges over this fifty year period could hold U.S. overall GHG emissions at a steady 7 gigatons. A wedge analysis can also illustrate strategies that can reduce emissions.

This graph shows wedge analysis at work for achieving real reductions from a prior baseline:

Pacala and Socolow defined and calculated their fifteen possible “wedges” in these categories:

Obviously, these are all big ticket items for national policy application. Campus wedges would be defined differently – perhaps one for each mitigation strategy detailed in Section 4 of this report or for different projects and measures. This graph illustrates Cornell University’s strategy for achieving climate neutrality:

Emissions reduction wedges are one tool of many that campuses can use to define, conceptualize or present their climate action plans. The Solutions Module of the CA-CP Campus Carbon Calculator Version 6 contains a wedge analysis tool

8. Financing Campus Climate Action

8.1 Dealing with Sticker Shock

At some point, most schools preparing a CAP will probably face “sticker shock.” This is likely to occur when the cost of actually achieving significant GHG emissions reductions is initially estimated and better understood as a result of the climate action planning process. The reality is that avoiding the worst consequences of climate change is a huge undertaking, and it shouldn’t surprise anyone that there are going to be real costs involved. On larger campuses, the costs of achieving climate neutrality or deep cuts in emissions may cost many millions of dollars and require substantial on-going costs. Balanced against those costs will be annual savings resulting from reduced waste and greater levels of efficiency.

Preparing the CAP can also be costly in terms of staff time. Dedicating existing staff to this process involves an “opportunity cost,” i.e. the functions and benefits those staff will not be able to achieve because they are instead focused on planning for and achieving GHG emissions reductions. Some may see this as a negative. Those concerned about environmental responsibility and the fate of the Earth may have another view since shifting resources toward saving the planet will seem like a good thing to them. One group likely to be pinched for time is campus sustainability staff who will probably be asked to do more even though they were already stretched thin before the CAP process began. Their own personal sustainability may be at risk. Energy managers asked to do more and more may find themselves in the same boat.

Energy conservation and energy efficiency improvements tend to be the primary GHG emissions mitigation strategies that can save enough money to pay for themselves. While short payback energy conservation projects can produce “positive cash flow” (savings in excess of cost or debt service) that can be used to leverage and pay for other measures, the deep conservation necessary for achieving significant GHG emissions cuts will probably entail an acceptance of energy conservation measures with longer paybacks and less attractive economics. These will erode the prospects of positive cash flow and limit the ability of conservation projects to produce a cash stream capable of financing other GHG emissions reduction strategies.

As the real costs are better understood, it is important that campus climate planners and activists think carefully and creatively about financing options and develop an effective financing strategy for their CAP. They also need to be very strategic in rationalizing the costs that are involved. One way of doing the latter is to be deliberate and meticulous in pointing out (and quantifying if you can) the multiple benefits produced by a campus climate action commitment and program. These are real and important and include:

The above, of course, is no substitute for a sound CAP financial plan but being clear about the important multiple benefits of this endeavor will take some of the bite out of discussions about the costs. A smart financial plan will prioritize cost-effective emissions mitigation measures, sequence and schedule them to maximize synergies and savings and allow some measures to pay for others, identify obvious and unusual funding sources, and use creative financing techniques to make serious climate action affordable.

8.2 Funding Sources

Projects, measures, and programs that reduce GHG emissions can be paid for by a variety of funding mechanisms including:

Affordability is a key factor that weighs heavily on whether a CAP actually gets implemented. This means minimizing costs while chasing all available dollars.

AASHE maintains a list of campus revolving funds. For more information on financing on-site renewable energy technologies, see The Business Case for Renewable Energy: A Guide for Colleges and Universities by Andrea Putman and Michael Philips (2006), Alternative Energy Economics by Michael Philips and Lee White (2009), and the Database of State Incentives for Renewables and Efficiency. In April, 2011, the ACUPCC launched the ACUPCC Financing Sustainability Project webpage with a suite of information and resources about different financing options.

9. Structuring Your Plan and Getting It Approved

9.1 Sample CAP Table of Contents

Here is a sample CAP table of contents:

9.2 Improving the Likelihood of CAP Approval

The CAP team’s first responsibility is producing the best possible climate action plan. But it’s not just about producing a report; it’s about gaining acceptance and approval for your plan so that it can be implemented. There are a variety of social strategies that campus climate action planners, activists and organizers can use to increase the likelihood that their climate action plans will receive administrative approval and thus move to the implementation phase. These include:

10. Implementing Your Campus Climate Action Plan

10.1 Increasing the Chances of Implementation

College and university veterans know that it is dangerous to make assumptions or believe that things will progress the way they should. Key people come and go. Nasty politics can assert themselves. Budgets can crash. And the best laid plans of mice and men (and women) can go awry.

While all campuses work differently, in general CAP implementation is more likely if a high ranking professional staff member – with direct access to the president and other campus leaders – is assigned the task of managing implementation. This individual can serve as staff to and leader of a CAP implementation committee or delegate those responsibilities to a direct-report staff person who handles CAP implementation day-to-day details. The implementation committee might evolve out of the planning committee and should remain inclusive and open.

Implementation is more likely to occur if progress (or lack of it) is regularly communicated to the administration and the campus community accompanied by efforts to maintain a high level of interest. On-going student interest and support is essential because students can more easily speak out than can staff members. Since students come and go on a regular cycle, educating and involving students will be an on-going process.

An annual progress report that is widely circulated and discussed is an important part of the implementation process. While an annual progress report can be used by ACUPCC institutions to meet program reporting requirements, more importantly each time one is released it will shine a light on your school’s climate action efforts and encourage renewed commitment. The report could contain an updated GHG inventory (the ACUPCC requires such updates every other year), a listing of measures and projects completed that year, and an assessment of whether climate commitment goals for that year were met. This should be an honest discussion and not just a PR piece.

10.2 Hold an Annual Climate Summit

An annual climate action summit is another helpful accountability mechanism for maintaining the commitment and achieving the targets and eventual long-term goals defined by your CAP. At the summit, your president can deliver a progress report to the campus community, have an opportunity to indicate his/her renewed commitment, and answer questions and respond to concerns. A series of panel discussions could be set up to report on progress in various mitigation areas as well as discuss difficulties that have been encountered and what is being done to overcome them. A nationally recognized expert keynote speaker could be invited to kick-off the summit by reminding everyone of the climate crisis we are facing and thus the importance of holding fast to the climate commitment.

While it might seem like Earth Day is a good time to hold the summit, it may be too late because on most campuses the school year is over in late April which is when Earth Day officially occurs. Kick-off the school year by holding your campus climate summit in mid-September or October. Call it your campus earth day if you want. Or schedule it on Campus Sustainability Day, a nationwide event sponsored by the Society for College and University Planning held in October each year.

10.3 CAP Flexibility and Revisions

Implementing a climate action plan is a learning process and thus requires a flexible approach which allows changes and incorporates lessons learned along the way. Flexibility is important so that your CAP can respond to new conditions, technologies, and opportunities and thus stay current. Revisions to the plan can be released or proposed each year when the annual progress report is issued or the annual summit is held or you could build into your plan a formal review and re-evaluation process every two or three years. Revisions would be developed by the chief CAP implementing officer and the CAP implementation committee as a result of a transparent, participatory process. But be careful to avoid unnecessary backsliding.

Periodic reviews and re-evaluations of you CAP have another advantage. They provide additional opportunities for student involvement so that new classes of students can participate in the CAP analytical and planning process, maximizing the educational benefit of the endeavor.

10.4 What if Your President Leaves?

One danger or contingency all colleges and universities face is that a supportive campus president will leave and be replaced by a new leader who is not as interested in developing or implementing a CAP. If this happens, a lot of ground can be lost. Thus it is imperative that campus supporters of your climate commitment and CAP strongly insist that the selection process for new campus leaders include a climate action “litmus test.” While all new college and university leaders can be expected to bring to their job a list of their own priorities, it is essential that climate protection and climate leadership be among their top concerns.

If despite these efforts the new president is less supportive, it is important that there is a broad and deep awareness and support of your campus climate action plan among faculty, students, staff, alumni, and trustees, so that any loss in momentum is minimal.

11. Concluding Remarks

We cannot stand idly by as the global climate shifts, creating an untenable world for future generations the other species with whom we share this increasingly small and fragile planet. Colleges and universities hold a unique position in our society and have a special obligation to demonstrate intellectual and moral leadership, set an example, and inspire hope and action in others. That’s what making a leadership commitment to addressing climate change is all about. The next few years are crucial so let’s get going!
