Not long ago small private colleges had a near monopoly on campus environmental initiatives in the United States. But today supersize public universities are nipping at the nimble, hemp-shod heels of those pioneers by adopting green building standards, expanding environmental studies programs, and converting fleets to zero-emission vehicles. This represents a dramatic shift even from last year, when Sierra ran its first "Cool Schools" roundup and filled all but two of the top ten spots with private colleges. In the following pages, you'll find a diverse mix of institutions-from North Carolina's 850-student Warren Wilson College to Arizona State University, the country's second-largest school with 51,500 students. The top schools earned points in ten categories: policies for building, energy, food, investment, procurement, and transportation; curriculum; environmental activism; waste management; and overall commitment to sustainability. A perfect score in every area would give a school 100 points.
