When deciding to attend a green college, there are certain criteria to consider when choosing the best green campus experience. The Princeton Review rated colleges based on whether students had a campus life that was healthy and had sustainable resources available.

Enlisting a panel of experts in green practices for higher education, school administrators at 629 colleges were surveyed and asked about school policies regarding recycling, LEED building standards and energy consumption for the green scale ranking.

If you are seeking a degree in environmental studies and sustainability, that’s a criteria for a college to be considered sustainable, according to Princeton Review methodology.

“Environmental literacy is becoming a core necessity, regardless of career or interest, as companies are increasingly asking employees to consider the bigger picture,” said Jared Duval, author of "Next Generation Democracy: What the Open Source Revolution Means for Power, Politics, and Change."

Organic food in the dining hall, access to mass transit and car pooling or telecommuting to class were also among the considerations included in the ranking.

The following U.S. colleges, in ascending order, were ranked the most green:

10. University of California-Davis

Davis, Calif.

Enrolled: 29,589

The school’s commitment to sustainability has led to “four consecutive years of reduced greenhouse gas emissions,” according to the survey. UC Davis is a bicycle “hotspot” with over 20,000 bicycles on campus almost daily. The campus food budget is 23 percent from local/organic sources.
