Colleges and universities around the world are enacting sustainable initiatives. Some are signing the American College and University President's Climate Committment, while others are being recognized by STARS (Sustainability, Tracking, Assessment, & Rating System). Despite what level of dedication to sustainability an institution might have, it is important that the administration supports the idea. This publication discusses sustainability in college unions and student activities. Topics covered include sustainability rating systems, college tours, sustainability blogs, fair trade, green cleaning, and so much more.
