The Princeton Review's Guide to 322 Green Colleges profiles 320 institutions of higher education in the United States and two in Canada that demonstrate a strong commitment to sustainability in their academic offerings, campus infrastructure, activities and career preparation. The guide is the only free, comprehensive, annually updated guide to green colleges.

To produce this book we partnered with the U.S. Green Building Council, an outstanding national nonprofit organization best-known for developing the LEED green building rating system. USGBC launched its Center for Green Schools in 2010 to increase its efforts to drive change in how campuses and schools are designed, constructed, and operated.
