The Intermountain Sustainability Summit has attracted between 400 to 600 sustainability professionals and emerging leaders from business, government, nonprofit and academic sectors.

The summit is hosted by Weber State’s Sustainability Practices and Research Center with influence from community partners, business, students and engaged citizens. It was started by a Weber State student as a recycling event in 2009, and formalized (in collaboration with the Utah Recycling Alliance) as the Intermountain Sustainability Summit the following year.

Summit speakers have deepened participant understanding of renewable energy, green buildings, electrification, transportation, climate change, social justice, new economic models and more. Keynotes in recent years have included luminaries such as Mary Robinson, Paul Hawken, Hunter Lovins, and Naomi Oreskes.
