RNG Continues to Lead as the Easy-to-Switch Clean Fuel for Multi-Sector Fleets Signing New Agreements With Clean Energy

Key Terms

renewable natural gas technical

Renewable natural gas is methane captured from organic waste—like landfills, farms, or wastewater—and cleaned to the same quality as conventional pipeline gas so it can be used for heating, electricity, or vehicle fuel. Investors care because it turns waste into a revenue-generating commodity, can qualify for carbon credits or government incentives, and can reduce a company's emissions profile, affecting long-term costs, regulatory risk, and market demand much like converting trash into sellable fuel.

rng technical

Renewable natural gas (RNG) is methane captured from organic waste sources—like landfills, farms, or wastewater—and cleaned to match the quality of conventional natural gas. For investors, RNG matters because it turns waste into a marketable, low-carbon fuel that can create new revenue streams, qualify for environmental credits, and reduce a company’s carbon footprint much like turning trash into a sellable product.

greenhouse gas (ghg) emissions technical

Greenhouse gas (GHG) emissions are gases released into the atmosphere—most commonly carbon dioxide, methane and nitrous oxide—that trap heat and raise global temperatures, like a blanket warming the planet. Investors watch GHG emissions because they influence regulatory costs, physical climate risks, insurance and supply-chain stability, and public reputation; companies with lower emissions may face fewer future expenses and attract more capital, while higher emissions can lead to fines, disruption or divestment.

methane technical

Methane is a colorless, odorless gas that is the main component of natural gas and is produced both naturally (from swamps, wetlands) and by human activity (fossil fuel production, agriculture). Investors care because methane is a potent greenhouse gas that can trigger tighter regulations, cleanup costs, or liability, and it also links directly to energy supply and prices—think of it as a hidden leak that can affect both a company’s costs and its regulatory risk.

NEWPORT BEACH, Calif.--(BUSINESS WIRE)-- Clean Energy Fuels Corp. (NASDAQ: CLNE), the largest provider of the cleanest fuel for the transportation market, has announced a slew of deals with trucking, refuse, and transit fleets nationwide. The agreements span renewable natural gas (RNG) fueling infrastructure and RNG supply, representing the continued growth of clean fuel adoption across multiple sectors.

“2025 was a rough year for other alternatives that didn’t live up to the hype. But fleets continue to seek proven solutions to meet sustainability targets and they’re finding that the RNG metrics deliver on multiple fronts – it’s clean, affordable, has diesel-like capability, is domestically produced, and there is a robust fueling infrastructure already in place,” said Chad Lindholm, senior vice president at Clean Energy. “These new agreements that we’re announcing today reflect that growing recognition across diverse fleet applications.”

Clean Energy has extended its partnership with Ecology Transportation Services, one of Southern California’s largest adopters of RNG for trucking. The agreement will supply Ecology’s fleet of 150 RNG vehicles with an estimated 2.1 million gallons of RNG annually. The trucks will fuel at Clean Energy stations across California, Arizona, and Nevada.

Clean Energy’s long-term partner Recology, one of the largest waste haulers in the western U.S., is expanding its commitment to RNG with upgrades to its fueling station in Seattle and a newly completed station in Snohomish, WA. Clean Energy will provide operations and maintenance services for both sites, supporting Recology’s growth in the greater Seattle region. Clean Energy continues to partner with WM, providing operations and maintenance services for more than 85 WM RNG stations across the U.S. and Canada, helping to keep 8,000 of WM’s RNG-powered refuse trucks on the road.

Washington Metropolitan Area Transit Authority (WMATA) has extended its relationship with Clean Energy, awarding a new operations and maintenance contract to support its natural gas bus fleet. The agreement covers five million gallons of fuel to support over 400 buses which will serve the local community. Clean Energy has provided services for WMATA stations for over a decade, and the transit agency recently commissioned two new natural gas stations to serve its fleet.

Clean Energy has signed an operations and maintenance agreement with ABM Facility Services to maintain three transit bus fueling stations for the City of Phoenix. Clean Energy has maintained the sites since 2016, which supply RNG to 335 natural gas buses, dispensing approximately 4.7 million gallons of fuel annually.

Clean Energy will begin providing RNG to 78 Arlington Transit (ART) buses in Virginia, totaling approximately 750,000 gallons annually. ART selected Clean Energy through a competitive process for RNG supply to support its GHG emissions reduction goals. Clean Energy will continue to provide repair and maintenance services to ART.

The City of Scottsdale, AZ, has extended its maintenance contract with Clean Energy to continue supporting 49 of its refuse vehicles with approximately 441,000 gallons of fuel each year. The city has long utilized natural gas vehicles for its waste operations, demonstrating its commitment to cleaner municipal services.

Clean Energy will continue to operate and maintain Nashville International Airport’s natural gas station under a new agreement to provide 63 shuttle buses and fleet vehicles with approximately 350,000 gallons of fuel annually. Since designing and building their fueling site in 2016, Clean Energy has helped the airport move towards cleaner ground transportation aligned with the airport’s sustainability goals.

The City of Fort Smith in Arkansas has signed an RNG supply agreement to fuel its refuse trucks. Clean Energy built the city’s RNG station in 2021 and continues to maintain the site since commissioning.

According to the EPA, agriculture accounts for nearly 10 percent of U.S. GHG emissions, and the transportation sector accounts for another 28%. Capturing waste methane from farms and turning it into a transportation fuel reduces emissions in both industries. RNG is one of the only fuels to receive a negative carbon-intensity rating, significantly lowering GHG emissions on a lifecycle basis when compared to diesel, and it costs significantly less than diesel at the pump.
