This free online resource lists the nearly 300 U.S. colleges and universities that scored in the 80th percentile or better in The Princeton Review's Green Ratings.

Compiled by The Princeton Review in collaboration with the U.S. Green Building Council, the guide details the green attributes of colleges and universities whose facilities, operations, administration and curriculum demonstrate "an exceptional commitment to sustainability," according to Princeton Review Senior Vice President and Publisher Robert Franek.

The 198-page “Guide To 286 Green Colleges” is available at www.princetonreview.com/greenguide and www.usgbc.org/campus. The Princeton Review and the USGBC released the guide to mark the 40th anniversary of Earth Day.
