Universities can teach and demonstrate environmental principles and stewardship by taking action to understand and reduce the environmental impacts of their own activities. This text a motivational and how-to guide for staff, faculty and students offers detailed "greening" strategies for those who may have little experience with institutional change or with the latest environmentally friendly technologies. The author was project manager of Tufts CLEAN!, a programme whose mission was to reduce Tufts University's environmental impact. After analyzing the campus's overall environmental impact, the team decided to focus on food waste, transportation, energy efficiency and procurement practices. An essential discovery was that to change practices requires the personal commitment and direct involvement of those who have the responsibility for operating the institution on a daily basis. Although the Tufts experience forms the basis for many of the proposals in the book, the story goes well beyond Tufts; the author includes examples of successful practices from many other institutions.
