NEW YORK, October 24, 2023 / — The Princeton Review®  today posted the 2024 edition of its annual Guide to Green Colleges—an online resource the company has published since 2010 for college applicants wanting to attend schools that foster a culture of environmental responsibility.

Based primarily on the company’s surveys of administrators at 683 colleges in 2022–23 and its analyses of more than 25 survey data points, the 2024 edition of the Guide features profiles of 522 schools. Schools that were selected for the Guide all have exceptional programs, policies, and practices related to sustainability and the environment. (See “How the Schools Were Chosen…” below.)

The Guide to Green Colleges is accessible for free at It feature profiles of the 522 schools with details on their green distinctions, academics, and admission requirements, plus a ranking list of the Guide’s Top 50 Green Colleges.

The College of the Atlantic in Maine earned the #1 spot on the Top 50 Green Colleges list for the 8th consecutive year. Its green distinctions are exceptional as is its mission: the College awards bachelor’s and master’s degrees exclusively in Human Ecology. The school became the first carbon-neutral college in the U.S. in 2007, and it has committed to becoming fossil fuel–free by 2030. It is also #1 on The Princeton Review ranking list, Green Matters: Everyone Cares About Conservation, one of 50 ranking list categories in the company’s book, The Best 389 Colleges: 2024 Edition.

Another school in Maine, Colby College, is #2 on the Top 50 Green Colleges list and also a carbon-neutral college. Its campus has more than 15 LEED (Leadership in Energy and Environmental Design)-certified buildings and spaces. New York University, #3 on the list, offers 20+ academic degrees and 600+ courses focused on sustainability. (A list of the top 25 schools on the top 50 list is below.) 

The Princeton Review’s release of its annual Guide to Green Colleges occurs during the annual October event, Campus Sustainability Month—an international celebration of sustainability in higher education by the Association for the Advancement of Sustainability in Higher Education (AASHE).

"With increasing concern about climate change, particularly among younger people who will be most affected by its long-term impact, we are seeing increasing interest among college applicants in attending green colleges” said Rob Franek, Editor-in-Chief, The Princeton Review. Of 8,800 applicants the company polled for its 2023 College Hopes & Worries Survey, 69% said having information about a college's commitment to the environment would affect their decision to apply to or attend the school. Of that cohort, 28% said such information would contribute “very much” or “strongly” to such a decision.

“Since we debuted our Green Guide 14 years ago, we have also seen dramatic growth in the number of colleges committing to sustainability-related practices—from sourcing food from local purveyors to constructing LEED- certified buildings to making fossil fuel-free commitments,” Franek added. “We are proud to shine our light on these exceptional schools. We recommend them enthusiastically to students who want their ‘best-fit’ college also to be a green one.”

How Schools Were Chosen for the 2024 Edition of this Guide

The Princeton Review chose the 522 colleges for this edition based on its 2022–23 survey of administrators at 683 colleges concerning their institutions' sustainability-related policies, practices, and programs. The company also surveyed students attending the colleges about their sustainability-related campus experiences. The company editors analyzed more than 25 data points from the surveys to tally Green Rating scores for the schools on a scale of 60 to 99. Colleges that earned a Green Rating of 80 or higher were selected for this edition of the Guide. Of the 522 schools selected, 474 are in the U.S., 30 are in Canada, four are in Ireland, three are in United Arab Emirates, two (each) are in Australia and Mexico, and one (each) is in Azerbaijan, Brazil, Colombia, Ecuador, Egypt, Greece, Morocco, Philippines, and Taiwan.

Forty of the 522 schools in the guide earned a Green Rating score of 99, the highest possible score. They are listed in The Princeton Review's Green Honor Roll (reported August 2023). The Princeton Review’s Green Rating scores appear in the profiles of the schools on and in the company’s book, The Best 389 Colleges: 2024 Edition (August 2023).

How the Top 50 Green Colleges Ranking List Was Tallied

The Princeton Review tallied this list based on data from its surveys of administrators at colleges in the Guide as well as its surveys of students attending the colleges. The methodology factored in ten data points from the administrator survey and three data points from the student survey. Data from the student survey included student assessments of the influence of sustainability issues on their academic and campus experiences; administrator and student support for environmental awareness and conservation efforts; and the visibility and impact of student environmental groups on the campus.
