The Princeton Review teamed up with the U.S. Green Building Council to produce its Guide to Green Colleges, which evaluates colleges and universities on their environmentally-related policies, practices and academic offerings. Schools are granted a numerical score on a scale of 60-99. The list recognizes the 24 schools that achieved The Princeton Review's highest Green Rating of 99 this year and a spot on its Green Honor Roll. Among them are American University (Washington, D.C.), University of Washington (Seattle, WA), Georgia Institute of Technology (Atlanta, GA), and Stanford University (Stanford, CA).
