As many environmental regulations in the United States are reconsidered and loosened, these colleges and universities are committed to cultivating sustainable campuses and future environmental leaders.

The vegetables harvested by students from University of California, Davis, go to the Yolo County Food Bank.

U.C. Davis is among the schools leading the way in emissions reduction and waste diversion. The university boasts the largest solar power plant on any campus and diverts 73 percent of its waste from landfills.
“We teach at least 180 courses a year with sustainability content,” says Camille Kirk, the school’s director of sustainability. “Our students are future leaders and active citizens, and they take their U.C. Davis training and go out and do great work in private, public and nonprofit settings.”
College of the Atlantic Ornithology students get a close-up view of some of the bird life in nearby Acadia National Park.

College of the Atlantic is a small school off the coast of Maine that has touted itself as a place “for idealists with elbow grease.”
It was the first school to achieve carbon neutrality, and nearly a decade ago, the school created one of the first sustainable enterprise incubators. Students have developed solar car charging stations, renewable power sources for local businesses and some of the early concepts of urban farms. About three-quarters of students continue to pursue these ventures after graduating, but according to sustainable development professor Jay Friedlander, that’s not the point. “It’s not about cranking out ventures,” he says. “It’s about students experiencing what it’s like to be a sustainable entrepreneur and to do that with a safety net.”
Stanford’s bicycle program accommodates an estimated 13,000 bikes on campus daily.

Stanford is a leader in two of California’s most critical measures of sustainability: transportation and water usage. In a state where transit is the biggest source of greenhouse gas emissions, 40 percent of campus cars are electric. Meanwhile, the university has reduced potable water use by 49 percent since 2000, helping to offset the effects of a three-year drought.
Stanford is not only building a sustainable community, but providing an open-source model for other institutions as well. “We very meticulously measure our performance,” says Fahmida Ahmed, director of sustainability. “So if there are any questions whenever others are inspired by Stanford and want to replicate that process for themselves, we can actually share that formula with them.”
Graduate students working in Colorado State University’s Horticultural Center.

Colorado State University was the world’s first university to achieve a platinum ranking under the Association for the Advancement of Sustainability in Higher Education’s STARS rating system. But the school’s commitment to the environment extends beyond its four walls — research from C.S.U. has been used in massive infrastructure projects and E.P.A. emissions reports, and the university is developing a test site to help companies control their methane emissions. In 2011, the school launched the Center for the New Energy Economy, which works with legislators and regulators to promote clean energy policy.
Green Mountain College has divested from fossil fuels.

This small liberal arts school in the mountains of Vermont was the second institution of higher learning in the country to become carbon neutral. It reportedly generates 85 percent of its heat from a biomass facility on campus that runs on local wood chips. G.M.C. also provides a compelling model in its spending and sourcing. “Where we spend our money matters for the environment and for social justice,” says the school’s sustainability page. The school was among the first American colleges to divest from fossil fuels, and purchases from suppliers that are local, transparent in their supply chain and ecologically responsible.
