Clean Energy Fuels Corp., the largest provider of renewable natural gas (RNG) for transportation, has announced a series of new agreements with trucking, refuse, and transit fleets across the U.S. and Canada. The deals cover RNG fueling infrastructure and supply, reflecting the continued growth of clean fuel adoption in diverse fleet applications.

Why it matters

RNG is emerging as a leading clean fuel solution for fleets seeking to meet sustainability targets, as it offers a domestically produced, affordable, and low-emission alternative to diesel. These new partnerships demonstrate the widespread adoption of RNG technology across multiple sectors, helping to reduce greenhouse gas emissions in both the transportation and agriculture industries.

The details

The new agreements include extending Clean Energy's partnership with Ecology Transportation Services in California, Arizona, and Nevada; expanding commitments with long-term partners Recology and WM; and securing new contracts with the Washington Metropolitan Area Transit Authority, the City of Phoenix, Arlington Transit in Virginia, the City of Scottsdale, Arizona, and the City of Fort Smith, Arkansas. In total, the deals cover the supply of millions of gallons of RNG annually to support thousands of natural gas-powered vehicles.

  • Clean Energy has provided operations and maintenance services for WM's RNG stations across the U.S. and Canada for over a decade.
  • The 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.
  • Clean Energy has maintained fueling stations for the City of Phoenix since 2016, supplying RNG to 335 natural gas buses.

What they’re saying

“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.”

The expansion of Clean Energy's RNG partnerships across diverse fleet sectors demonstrates the growing recognition of RNG as a practical and effective solution for reducing greenhouse gas emissions in transportation. As fleets seek to meet sustainability goals, RNG's combination of environmental benefits, cost-competitiveness, and existing infrastructure make it an increasingly attractive fuel choice.
