Sierra Ranks Top 10 Greenest Universities in the US

Sierra has been ranking America's greenest colleges for seven years now, so we know what a difference a campus can make.

With each "Cool Schools" issue sent to press, we are reminded that LEED-certified buildings equipped with low-flow toilets and stocked with recycling bins push carbon dioxide levels lower and keep reservoirs fuller, landfills emptier, and trees standing longer.

But what of the students? The most powerful renewable energy resource these campuses generate is freshly educated young people. And colleges crow that instilling eco-literacy — teaching youths about the state of our planet — will put us on the right path. Will it, though?

We set out to find out, and it looks like the answer is yes.

Only a few universities actually gauge whether their environmental curriculum makes a difference after students graduate. But the anecdotal evidence is heartening: Story after story confirms that the environmentalism surrounding students during college sticks with them.

A single class or professor can turn a life verdant. Spending four years in a place that grows its own organic food, runs on alternative energy, composts, limits cars, and pursues goals like becoming carbon-neutral or zero-waste leaves an imprint. Meanwhile, community colleges and vocational schools are bulking up the green-collar workforce.

Of course, it's easier to measure bricks and mortar than hearts and minds, so our ranking remains focused on the more quantifiable aspects of how schools operate. This year's list is the result of an extensive questionnaire that asks about everything from where a campus gets its energy to whether its landscapers use native plants and its cafeterias offer recycled napkins.

We got responses from 162 qualified schools, then crunched the numbers. A perfect score would have been 1,000. Our top-ranked school netted 850, proving that even the nation's best has room to improve.

10. University of California, Santa Barbara

Santa Barbara, California 

Score: 756.69 | Students: 22,218

UCSB puts up formidable numbers: 44 of its buildings are LEED certified, 47 percent of academic departments offer a class about sustainability (for a total of 321 classes and 217 faculty members who do eco-research), 50 percent of food served is local, and 75 percent of waste gets saved from the landfill via recycling and composting; the goal is to get that latter percentage to 100 by 2020. The Gauchos have also, since the late 1990s, lowered their electricity use by a third (10 on-campus photovoltaic systems help), their water use by a quarter, and their food waste by almost 35 percent. A whopping 94 percent of students take alternative means of transit to class — there are more than 10,000 bicycle parking spaces on campus to accommodate 10 miles of bike paths.

9. American University

Washington, D.C

Score: 759.34 | Students: 12,693

Aiming to be carbon neutral by 2020, AU is off to a strong start, with 30 buildings on track for LEED Silver certification, a 27-kilowatt solar array, D.C.'s biggest solar hot-water system, and a contraption called the Vegawatt, which turns old cooking oil into electricity. The university's plan is to divert 100 percent of its waste, and it's already two-thirds of the way there, thanks to a new campus-wide composting program, trayless dining (which reduced food waste by a third), quarterly e-waste drives, and such enthusiastic student participation that AU won last year's national RecycleMania competition. Students also get excited about the annual Campus Beautification Day (shown above), a springtime tradition that brings the AU community together to make the campus greener.

8. Georgia Institute of Technology

Atlanta, Georgia 

Score: 759.76 | Students: 20,941

The EPA named Georgia Tech one of the "best places for commuters" for its range of eco-transit options, from carpooling to mass transit; natural gas–powered buses move more than 2 million riders per year. Above, as part of Georgia Tech's annual Earth Day celebration — one of the Southeast's biggest — student volunteers offer free bicycle repairs. The 440-acre Atlanta school was also named a Tree Campus USA for its 25 percent arboreal cover. Despite all that foliage, water usage hasn't increased since 2001 — impressive, considering that the school's interior square footage has doubled since then. Everything built after 2008 is LEED certified, and a 1.4-million-gallon stormwater cistern helps conserve. The Yellow Jackets have been recycling since 1996, diverting an annual mass of 600 tons.

7. Stanford University

Palo Alto, California 

Score: 763.82 | Students: 15,666

"Sustainability must become a core value in everything we do," wrote Stanford president John Hennessy. Over five years, the California school raised more than $430 million for its Initiative on the Environment and Sustainability, a chunk of which is headed toward a new energy facility that'll halve the 8,180-acre campus's carbon emissions and cut its water use by almost a fifth. Some 130 professors spanning 40 departments teach at least 700 sustainability-related classes. No surprise, then, that three dozen student clubs are green-themed and that recycling and composting are big: The waste-diversion rate here tops 66%, and the goal is zero waste. The students in the above photo might look like lacrosse players, but they're members of the Stanford Gleaning Project on their way to harvest loquats from the campus's Main Quadrangle; the fruit is donated to local hunger-relief organizations.

6. Green Mountain College

Poultney, Vermont 

Score: 767.09 | Students: 637

With grounds as verdant as its name, GMC is a tiny school in Poultney, Vermont, that describes itself as "a liberal-arts college emphasizing environmental sustainability." One of the first U.S. universities to achieve climate neutrality, it has a $5.8 million biomass plant that burns locally sourced woodchips (instead of fuel oil) to heat 85 percent and power 20 percent of the campus's two dozen buildings. Since 2006, GMC has also sourced 1.2 million kilowatt-hours of its energy per year from cows. Students visit local farms to learn about the bovine methane-generating process and are required to take a 37-credit environmental curriculum, which is delivered in LEED-certified classrooms. Above, GMC students plant trees to create a riparian buffer along the banks of the Poultney River.

5. Cornell University

Ithaca, New York 

Score: 776.72 | Students: 21,131

Cornell offers 340 classes, across almost every department, about sustainability, and this is one of the only colleges where you can minor in climate change. School officials pledge that Cornell will be a net-zero-carbon campus by 2050. Over the past two years, its greenhouse gas emissions have dropped by 25 percent, and over the next five, $45 million will go toward energy-conservation projects: Cornell has already added more than 1 million square feet of new construction without needing to use any additional power. Plenty of open space remains, however: The 2,300-acre campus in Ithaca, New York, has two stunning gorges, a 35-acre botanical garden, and a 100-acre arboretum. Above, at the annual Slope Day, celebrating the last day of classes, student volunteers collect recyclables and compostables.

4. University of California, Davis

Davis, California 

Score: 782.74 | Students: 32,653

Last year's "Cool Schools" winner, an agricultural-education powerhouse, churns out research that helps shape California's water laws and push new farming practices into the mainstream. Its West Village, a neighborhood for students and staff, is America's biggest planned zero-net-energy community. UC Davis's climate action plan has already cut campus emissions to below year-2000 levels. Recycling, composting, and reuse divert more than 60 percent of would-be trash from landfills, and the Aggies aim to lift that percentage to 100 by 2020.

3. University of California, Irvine

Irvine, California 

Score: 794.30 | Students: 27,479

UC Irvine's 19-megawatt cogeneration facility and other energy-preserving projects have helped the school save 20 million kilowatt-hours of electricity per year since 2009 — and solar panels generate enough power to run 500 homes for a year. The 1,475-acre campus is anchored by a 16-acre botanical garden, and all new buildings must be certified at least LEED Silver. Living green is important at UCI: Meatless Mondays are strongly encouraged, and a dozen student clubs focus on eco-issues. Above, graduate students in UCI's Earth System Science Department learn about Mono Lake's geology, ecology, natural history — and about environmentalists' efforts to protect the lake — during a spring-break field trip.

2. Dickinson College

Carlisle, Pennsylvania 

Score: 807.04 | Students: 2,380

Since 2008, Dickinson has bought enough wind power to offset all of its electrical needs. And since 2006, students have been collecting grease from local restaurants and turning it into biodiesel for the Carlisle, Pennsylvania, campus's vehicle fleet. If all goes according to plan, the school will achieve zero net emissions by 2020. Meanwhile, cafeterias serve student-grown produce, construction crews build to LEED Gold standards, and paper use has dropped by 60 percent over the past four years. Above, students install solar panels to power an irrigation pump at Dickinson's certified-organic College Farm.

1. University of Connecticut

Storrs, Connecticut 

Score: 850.14 | Students: 22,301

This year's winning school offers almost 600 sustainability-related classes taught by some of the greenest minds anywhere — more than 40 percent of UConn's research faculty does original academic work that benefits the environment. Since 2005, the main campus, in Storrs, has slashed its water use by 15 percent — and over the past two years, 13 of its buildings were retrofitted to prevent 2,640 tons of carbon dioxide emissions annually. In the trayless dining halls, 30 percent of meal options are vegetarian, and more than a quarter of the food is processed within 100 miles, with many ingredients harvested right on campus: Honey comes from UConn's apiaries, fresh eggs from the agriculture department, and seasonal produce from student-run gardens (shown above). Farther afield, the school's Forest Committee tends more than 2,000 acres of open space.

Methodology

Participation

Participation in Sierra magazine's Cool Schools ranking is open to all four-year undergraduate colleges and universities in the United States. This year, campus administrators could participate by going to stars.aashe.org to complete an extensive questionnaire about their school's sustainability practices. Schools that submitted complete, updated data starting on June 2, 2013 or thereafter were eligible for this year's rankings.

Sierra received 162 complete responses from qualified colleges. Once schools submitted their data, researchers scored each response and ranked all the participating institutions. There was no cost for participation, and no affiliation or relationship between a school and the Sierra Club or its employees, past or present, influenced the ranking.

Survey

The survey, officially called the Campus Sustainability Data Collector, is the result of the collaborative efforts of four organizations: the Sierra Club, the Association for the Advancement of Sustainability in Higher Education (AASHE), the Sustainable Endowments Institute (SEI), and the Princeton Review, it is something of an amalgamation of all four organizations' questionnaires of recent years. Its questions center on measurable environmental achievements and goals, with priority given to achievements. (Schools did not need to be members of AASHE's STARS program to use the collector if they chose to share their data with Sierra.)

The purpose of this collaboration was to reduce the amount of time campus staffers spend completing separate surveys. Together, the groups sought to streamline the schools' reporting process to more closely resemble the way campuses already collect and report sustainability data. Another benefit of this collaborative questionnaire: It allows for a broad, deep investigation into a wide variety of environmental efforts while aiming to reduce college administrators' reported "survey fatigue" of years past.

Evaluation

Evaluation was based primarily on schools' responses to the survey but when appropriate, we made follow-up inquires by phone and e-mail and used publicly available outside sources to verify and complement survey responses. Final ranking decisions, however, were based on our scoring key, a rubric which emphasizes the Sierra Club's environmental priorities and rewards schools that do a good job of measuring and mitigating their impact. When it came to survey responses, all submitted materials were considered, though where answers were blank, unclear, or inconsistent, institutions were not awarded full credit.

Results

The resultant Cool Schools ranking is an index that provides fair, comparative information about the most important elements of campus sustainability. The results suggest that while many universities are making admirable progress, no school has yet attained complete sustainability. The top-rated university scored 850 (out of a possible 1,000 points), indicating much work completed and also room for improvement.

The United States has more than 2,000 four-year colleges and universities, so there are, of course, schools that care about the environment that don't appear on Sierra's list. That said, the magazine's ranking aims to act as a guide for prospective students who seek a way to compare colleges based on their commitment to environmentalism. It also serves to spur competition, create aspirational standards, and publicly reward the institutions that work hard to protect the planet.

Special Thanks

Sierra is grateful to researchers Don Dresser, Jake Abrahamson, and Robert Cuttino for their valuable work in developing this methodology and handling the surveys and scoring process.
