The Association for the Advancement of Sustainability in Higher Education (AASHE), is a membership-based association of colleges and universities working to advance sustainability in higher education in the US and Canada. They work on many levels, including cutting down on over consumption on campus. They work in partnership with businesses, NGO's and government agencies that support this mission.
