The Princeton Review Guide to Green Colleges- 2026 Edition was created based on a 25-question survey that gathered information about each institution's sustainability-related policies, practices, and programs. Students were also surveyed about their experience at the school, including administrator and student support for environmental awareness and conservation efforts on the campus.
The collected data was analyzed to tally Green Rating scores for the institutions as a measure of the school's performance as an environmentally aware and prepared institution, reported on a scale of 60 to 99. Northern Michigan University is proud to be featured in the Princeton Review Guide to Green Colleges 2026 with a score of 90/99!
