The primary function of an alumni sustainability network is to provide a mechanism for alumni to support campus sustainability initiatives. Alumni networks can mobilize members to lobby administrators on sustainability issues. Since their membership often includes professionals working in sustainability fields, alumni networks can also provide guidance, mentoring, and technical expertise to support campus sustainability efforts.
