In the 12 years since Sierra began highlighting the best environmental practices of colleges and universities, the competition to be the ecofriendliest in all of academia has gotten fierce. This year, we received a record 269 responses from qualified institutions, which now include Canadian schools and community colleges. Our annual Cool Schools Rankings assess colleges' performance in everything from what they teach to how they obtain their electricity to their sources of cafeteria food and how they manage their water. Please join Sierra in congratulating the very green—and diverse—schools that are mastering the art and science of campus sustainability.
20. Cornell University — Score 74.47 | Ithaca, New York
ANABEL'S GROCERY IS A STUDENT-RUN INITIATIVE DESIGNED TO COMBAT FOOD INSECURITY ON THE CORNELL CAMPUS, PROVIDING LOW-COST GROCERIES TO STUDENTS.CORNELL UNIVERSITY
Last year, Cornell launched Anabel's Grocery, a student-run food supply providing low-cost access to local, organic, and culturally inclusive foods. It also broke ground on the Sustainable Landscapes Trail, designed to highlight 14 campus spots that showcase Cornell's commitment to natural lands management (think rainwater capture stations, pollinator plants, and permaculture plots). Since 2008, this Ivy has reduced campus emissions by 36 percent and cooling energy by 86 percent, largely through proprietary innovations such as Lake Source Cooling—running a pump from one of upstate New York's nearby deep lakes to pipe cold water through campus. The Touchdowns are now experimenting with Earth Source Heat, a new system that involves drilling into the earth's upper crust and piping thermal heat through the often-chilly campus.
19. Loyola Marymount University — Score 74.74 | Los Angeles, California
LOYOLA'S OFFICE OF SUSTAINABILITY AND STUDENTS DESIGNED AND BUILT A SOLAR GOLF CART. LOYOLA MARYMOUNT UNIVERSITY
Not only has LMU operated a self-funded recycling plant since 1990, but it also won Los Angeles's inaugural "RecycLA" platinum award this year, thus becoming a model for the rest of the city. LMU was also the first university to sign onto the Lonely Whale Foundation's pledge to purge plastic straws. "The Cycling Lion," a shipping container turned bicycle hub, offers a recycled bike shop and bike-share program. The Lions are on track to divert all food waste by the end of 2019, thanks to a campus-wide food waste disposal and awareness program and a robust composting program. Students also work within a nearby underserved neighborhood to boost awareness of composting, provide food waste options, and develop a community garden.
18. University of Dayton — Score 74.93 | Dayton, Ohio
UD'S FIRST GREEN ROOF ON THE KENNEDY UNION PATIO, THE CULMINATION OF YEARS OF WORK BY STUDENTS, FACULTY, AND STAFF IN MANY AREAS ACROSS CAMPUS.BRUCE DAMONTE
The first Catholic university in the nation to divest from fossil fuel companies also has an Energy Team composed of students who work with campus facilities departments to perform energy and lighting audits. The team proposes and implements conservation projects, the funding for which often comes from UD's green revolving fund, which pays for itself through energy and other environmental savings. UD boasts low-flow showerheads and 1.3-and-counting megawatts of solar. Students living in university-owned campus houses receive feedback on their energy usage (their "energy GPAs"). Dayton Flyers can study environmental biology, pursue master's degrees in renewable and clean energy, and work the earth at nearby Lincoln Hill Garden, an urban farm and community green space the school established with community partners
17. Lewis & Clark College — Score 75.05 | Portland, Oregon
LEWIS & CLARK STUDENTS PARTICIPATE IN NUMEROUS MODES OF ACTIVE TRANSIT, INCLUDING BIKING, WALKING, TAKING THE BUS, AND CARPOOLING. LEWIS & CLARK COLLEGE
In the past year, Lewis & Clark has committed to selling off its fossil fuel investments, passed a policy to phase out all single-use plastics, and launched a "Hot Topics" series through which speakers come to campus to discuss issues such as environmental justice, biodiversity, and socially responsible investing. The school's Farm to Fork Initiative mandates that campus dining spend 20 percent of its funding on food sourced from small, local farms and producers, and the campus, which runs into two watersheds, recently re-upped its Salmon Safe designation. Lewis & Clark students can study ecopsychology and natural resources law, and take classes in the political economy of food. When they're not in class, many are involved with extracurricular pursuits including the beekeeping club, bike co-op, and garden collective.
16. University of Oregon — Score 75.42 | Eugene, Oregon
ALLAN PRICE SCIENCE COMMONS IS ONE OF THE SCHOOL'S NEWEST LEED GOLD-CERTIFIED BUILDINGS.UNIVERSITY OF OREGON
A year and a half ago, student activists pressured the University of Oregon to renew its climate action plan. As a result, the school has already reinsulated 16 miles' worth of campus steam and condensate pipes, thus reducing at least 54 metric tons of annual greenhouse gas emissions. The Ducks' new-and-improved climate plan is also funding environmental economists' research into internal carbon taxes that U of O, and perhaps eventually other institutions, could implement. The university is currently installing a shipping container outfitted with LED lights wherein students can experiment with the latest in indoor agriculture and recently received a grant to integrate sustainability courses with the work of area municipalities and nonprofits—meaning students will be working to solve real-world energy and transportation issues. Through "rEV Up Eugene," the University of Oregon hosts free community workshops about electric vehicles.

OSU STAFF MOVE MATERIALS DURING THE MOVE OUT DONATION DRIVE, WHICH IN 2018 COLLECTED OVER 32,300 POUNDS OF REUSABLE MATERIAL.OREGON STATE UNIVERSITY
Oregon State's trustees are in the process of developing a plan to divest a portion of its funding from fossil fuels and to diversify its portfolio of carbon-free funds. Meanwhile, students are enrolling in programs such as "humanitarian engineering," "sustainable agroforestry," and "sustainable cemeteries management." The consumption-wary Beavers have a textbook loan program in place as well as an "OSUsed" store and cap-and-gown return program. OSU dorms employ Eco-Reps, who educate residents on green lifestyle practices, and the school works with local food distributors, caterers, and restaurants to divert food waste to its campus food pantry.
14. Chatham University — Score: 76.09 | Pittsburgh, Pennsylvania
EDEN HALL CAMPUS.CHATHAM UNIVERSITY
No matter their major, every undergrad at Chatham must take sustainability courses, and most undergrads, grad students, and MBAs pursue degrees in sustainability or food studies. This year, Chatham is launching a new program to help prepare nursing students and other future health professionals for climate-change-induced public health threats. Thanks to its solar thermal greenhouse and "work-and-pick" garden, Chatham produces enough food to help supply its dining hall. Many students recently banded together to present a divestment proposal. Good news: Chatham's Board of Trustees is likely to approve it by October.
13. Santa Clara University — Score 76.13 | Santa Clara, California
SCU'S CENTER FOR SUSTAINABILITY HOSTS A "WASTE CHARACTERIZATION" ALMOST EVERY QUARTER FOR STAFF, FACULTY, AND STUDENTS. SANTA CLARA UNIVERSITY
Nine out of 10 students attending the "Jesuit University in Silicon Valley" engage in community-based learning for course credit. A food justice outreach program, for instance, works within marginalized neighborhoods to bolster community gardens and helps elementary students to develop urban gardens. Thanks to a deal wherein faculty can receive stipends to integrate eco- and/or social justice-oriented curricula into their syllabi, 93 percent of Santa Clara departments offer sustainability courses. The Broncos are currently working to reduce their food waste by 20 percent by 2025 and to increase the use of the school garden's on-site composting center.

STERLING COLLEGE STUDENTS PREP SEED POTATOES FOR PLANTING WHILE A CLASS PREPARES A HUGELKULTURE BED, A PERMACULTURE TECHNIQUE FOR MAKING A RAISED BED (BACKGROUND). STERLING COLLEGE
At Sterling, where most students labor on farms and forestlands in exchange for tuition (and produce upwards of 30 percent of food served on campus), the focus is on how best to steward working landscapes. So it's fitting that students are putting Wendell Berry's writing to work through a new partnership with the Berry Center, located in the author-activist's native Henry County, Kentucky. Each semester, students have opportunities to go south and help cultivate a different landscape. Meanwhile, Sterling faculty is developing curricula for Kentuckians seeking to implement holistic and sustainable farm plans. Back in Vermont, students are learning the craft of woodworking using ecologically harvested timber at Sterling's new Rural Arts Center.

SEATTLE UNIVERSITY STUDENTS AND STAFF SORT ONE DAY'S WORTH OF TRASH AT THE ANNUAL GARBOLOGY EVENT. SEATTLE UNIVERSITY
Seattle U students put the fossil fuel divestment challenge to their administration six years ago and never piped down. As a result, the trustees are on track to approve divestment this fall. The very edible campus has been pesticide-free since 1979, and its 50-acre urban wildlife sanctuary is designed to attract birds with lush, native flora. Every other year, the Redhawks host an environmental justice summit, which this year will ignite student and faculty activism around restoring the nearby Duwamish River, Washington's most industrialized waterway. Seattle U is working to become carbon negative by 2020.

Unity Task Forces formed by presumptive Democratic presidential nominee Joe Biden and Sen. Bernie Sanders unveiled sweeping party platform recommendations Wednesday that—while falling short of progressive ambitions in a number of areas, from climate to healthcare—were applauded as important steps toward a bold and just policy agenda that matches the severity of the moment.
"We've moved the needle a lot, especially on environmental justice and upping Biden's ambition," said Sunrise Movement co-founder and executive director Varshini Prakash, a member of the Biden-Sanders Climate Task Force. "But there's still more work to do to push Democrats to act at the scale of the climate crisis."
The climate panel—co-chaired by Rep. Alexandria Ocasio-Cortez (D-N.Y.) and former Secretary of State John Kerry—recommended that the Democratic Party commit to "eliminating carbon pollution from power plants by 2035," massively expanding investments in clean energy sources, and "achieving net-zero greenhouse gas emissions for all new buildings by 2030."
In a series of tweets Wednesday night, Ocasio-Cortez—the lead sponsor of the House Green New Deal resolution—noted that the Climate Task Force "shaved 15 years off Biden's previous target for 100% clean energy."
"Of course, like in any collaborative effort, there are areas of negotiation and compromise," said the New York Democrat. "But I do believe that the Climate Task Force effort meaningfully and substantively improved Biden's positions."
Today the 6 Biden-Sanders Unity Task Forces are unveiling final language. The Climate Task Force accomplished a gr… https://t.co/gz3broq2qe— Alexandria Ocasio-Cortez (@Alexandria Ocasio-Cortez)1594240617.0
The 110 pages of policy recommendations from the six eight-person Unity Task Forces on education, the economy, criminal justice, immigration, climate change, and healthcare are aimed at shaping negotiations over the 2020 Democratic platform at the party's convention next month.
Sanders said that while the "end result isn't what I or my supporters would've written alone, the task forces have created a good policy blueprint that will move this country in a much-needed progressive direction and substantially improve the lives of working families throughout our country."
"I look forward to working with Vice President Biden to help him win this campaign," the Vermont senator added, "and to move this country forward toward economic, racial, social, and environmental justice."
Biden, for his part, applauded the task forces "for helping build a bold, transformative platform for our party and for our country."
"I am deeply grateful to Bernie Sanders for working with us to unite our party and deliver real, lasting change for generations to come," said the former vice president.
On the life-or-death matter of reforming America's dysfunctional private health insurance system—a subject on which Sanders and Biden clashed repeatedly throughout the Democratic primary process—the Unity Task Force affirmed healthcare as "a right" but did not embrace Medicare for All, the signature policy plank of the Vermont senator's presidential bid.
Instead, the panel recommended building on the Affordable Care Act by establishing a public option, investing in community health centers, and lowering prescription drug costs by allowing the federal government to negotiate prices. The task force also endorsed making all Covid-19 testing, treatments, and potential vaccines free and expanding Medicaid for the duration of the pandemic.
"It has always been a crisis that tens of millions of Americans have no or inadequate health insurance—but in a pandemic, it's potentially catastrophic for public health," the task force wrote.
Dr. Abdul El-Sayed, a former Michigan gubernatorial candidate and Sanders-appointed member of the Healthcare Task Force, said that despite major disagreements, the panel "came to recommendations that will yield one of the most progressive Democratic campaign platforms in history—though we have further yet to go."
We rein in #pharma's greed by: 1) Allowing Medicare to FINALLY negotiate Rx drugs FOR ALL AMERICANS 2) Using Rx d… https://t.co/6k9iUCLMp7— Abdul El-Sayed (@Abdul El-Sayed)1594238411.0
Observers and advocacy groups also applauded the Unity Task Forces for recommending the creation of a postal banking system, endorsing a ban on for-profit charter schools, ending the use of private prisons, and imposing a 100-day moratorium on deportations "while conducting a full-scale study on current practices to develop recommendations for transforming enforcement policies and practices at ICE and CBP."
Marisa Franco, director of immigrant rights group Mijente, said in a statement that "going into these task force negotiations, we knew we were going to have to push Biden past his comfort zone, both to reconcile with past offenses and to carve a new path forward."
"That is exactly what we did, unapologetically," said Franco, a member of the Immigration Task Force. "For years, Mijente, along with the broader immigrant rights movement, has fought to reshape the narrative around immigration towards racial justice and to focus these very demands. We expect Biden and the Democratic Party to implement them in their entirety."
"There is no going back," Franco added. "Not an inch, not a step. We must only move forward from here."

Natural gas is a versatile fossil fuel that accounts for about a third of U.S. energy use. Although it produces fewer greenhouse gas emissions and other pollutants than coal or oil, natural gas is a major contributor to climate change, an urgent global problem. Reducing emissions from the natural gas system is especially challenging because natural gas is used roughly equally for electricity, heating, and industrial applications.

What RNG Is and Why it Matters<p>Most equipment that uses energy can only use a single kind of fuel, but the fuel might come from different resources. For example, you can't charge your computer with gasoline, but it can run on electricity generated from coal, natural gas or solar power.</p><p>Natural gas is almost pure methane, <a href="https://www.eia.gov/energyexplained/natural-gas/" target="_blank">currently sourced</a> from raw, fossil natural gas produced from <a href="https://www.eia.gov/energyexplained/natural-gas/where-our-natural-gas-comes-from.php" target="_blank">deposits deep underground</a>. But methane could come from renewable resources, too.</p><p><span></span>Two main methane sources could be used to make RNG. First is <a href="https://www.epa.gov/ghgemissions/inventory-us-greenhouse-gas-emissions-and-sinks" target="_blank">biogenic methane</a>, produced by bacteria that digest organic materials in manure, landfills and wastewater. Wastewater treatment plants, landfills and dairy farms have captured and used biogenic methane as an energy resource for <a href="http://emilygrubert.org/wp-content/uploads/2019/02/eia_860_2017_map.html" target="_blank">decades</a>, in a form usually called <a href="https://www.eia.gov/energyexplained/biomass/landfill-gas-and-biogas.php" target="_blank">biogas</a>.</p><p>Some biogenic methane is generated naturally when organic materials break down without oxygen. Burning it for energy can be beneficial for the climate if doing so prevents methane from escaping to the atmosphere.</p>
Renewable Isn’t Always Sustainable<p>If RNG could be a renewable replacement for fossil natural gas, why not move ahead? Consumers have shown that they are <a href="https://www.nrel.gov/analysis/green-power.html" target="_blank">willing to buy renewable electricity</a>, so we might expect similar enthusiasm for RNG.</p><p>The key issue is that methane isn't just a fuel – it's also a <a href="https://www.eia.gov/environment/emissions/ghg_report/ghg_overview.php" target="_blank">potent greenhouse gas</a> that contributes to climate change. Any methane that is manufactured intentionally, whether from biogenic or other sources, will contribute to climate change if it enters the atmosphere.</p><p>And <a href="http://doi.org/10.1126/science.aar7204" target="_blank">releases</a> <a href="https://doi.org/10.1016/j.wasman.2019.07.029" target="_blank">will happen</a>, from newly built production systems and <a href="https://theconversation.com/why-methane-emissions-matter-to-climate-change-5-questions-answered-122684" target="_blank">existing, leaky transportation and user infrastructure</a>. For example, the moment you smell gas before the pilot light on a stove lights the ring? That's methane leakage, and it contributes to climate change.</p><p>To be clear, RNG is almost certainly better for the climate than fossil natural gas because byproducts of burning RNG won't contribute to climate change. But doing somewhat better than existing systems is no longer enough to respond to the <a href="https://doi.org/10.1038/nclimate2923" target="_blank">urgency</a> of climate change. The world's <a href="https://www.ipcc.ch/sr15/chapter/spm/" target="_blank">primary international body on climate change</a> suggests we need to decarbonize by 2030 to mitigate the worst effects of climate change.</p>
Scant Climate Benefits<p><a href="https://iopscience.iop.org/article/10.1088/1748-9326/ab9335/meta" target="_blank">My recent research</a> suggests that for a system large enough to displace a lot of fossil natural gas, RNG is probably not as good for the climate as <a href="https://investor.southerncompany.com/information-for-investors/latest-news/latest-news-releases/press-release-details/2020/Southern-Company-Gas-grows-leadership-team-to-focus-on-climate-action-innovation-and-renewable-natural-gas-strategy/default.aspx" target="_blank">is publicly claimed</a>. Although RNG has lower climate impact than its fossil counterpart, likely high demand and methane leakage mean that it probably will contribute to climate change. In contrast, renewable sources such as wind and solar energy do not <a href="https://www.eia.gov/environment/emissions/carbon/" target="_blank">emit climate pollution directly</a>.</p><p>What's more, creating a large RNG system would require building mostly new production infrastructure, since RNG comes from different sources than fossil natural gas. Such investments are both long-term commitments and opportunity costs. They would devote money, political will and infrastructure investments to RNG instead of alternatives that could achieve a zero greenhouse gas emission goal.</p><p>When climate change first <a href="https://www.nytimes.com/1988/06/24/us/global-warming-has-begun-expert-tells-senate.html" target="_blank">broke into the political conversation</a> in the late 1980s, investing in long-lived systems with low but non-zero greenhouse gas emissions was still compatible with aggressive climate goals. Now, zero greenhouse gas emissions is the target, and my research suggests that large deployments of RNG likely won't meet that goal.</p>
