RNG Coalition, the nonprofit trade group representing the North American renewable natural gas (RNG) industry, is marking 15 years of operation alongside a milestone in the sector it represents: more than 600 operational RNG facilities now running across the continent.
The North American RNG portfolio has reached 604 operational facilities, following a rapid run of growth that saw the industry pass 300 facilities in 2023, 400 in 2024, and 500 in 2025.
Yolo County Landfill Project Turns Methane Into Renewable Natural Gas
Yolo County, California is moving forward with a project to replace the aging gas-to-electricity system at the Yolo County Central Landfill with a facility that converts landfill gas into renewable natural gas (RNG). The Board of Supervisors approved a 20-year agreement with Yolo RNG, LLC, effective July 1, and once complete in summer 2028 the facility will process all collected landfill gas into pipeline-quality RNG for injection into PG&E’s system.
Randolph County Selects Waga Energy to Convert Landfill Gas into RNG in North Carolina
Randolph County, North Carolina has selected Waga Energy to finance, build, own and operate a renewable natural gas (RNG) production unit at the Great Oak Landfill in Randleman under a 20-year agreement. Using the company’s patented WAGABOX technology, the facility will upgrade landfill gas into pipeline-quality RNG, producing roughly 610,000 MMBtu per year and avoiding an estimated 47,500 tons of CO2-equivalent emissions annually.
RNG-Powered Fleets Remain Carbon-Negative in California
Commercial fleets fueled by renewable natural gas (RNG) in California achieved carbon-negative transportation outcomes for the sixth consecutive year in 2025, according to a report from The Transport Project, RNG Coalition and the California Renewable Transportation Alliance.
Rebuilding effort Presents Call To Climate-Proof Our Energy System
Washington secured a federal major disaster declaration in April after a months-long push by Gov. Ferguson and the state's congressional delegation, unlocking federal aid to address an estimated $182.3 million in damage to public infrastructure from the December 2025 flooding. Federal Public Assistance and Hazard Mitigation funds will now prove vital to rebuilding the roads, levees, water systems and public buildings lashed by Mother Nature when three of the state's largest rivers — the Skagit, Snohomish and Cedar — reached their highest levels in recorded history.
But rebuilding should mean more than simply restoring what was — Washington can find a silver lining in disaster by rebuilding in a way that climate-proofs the systems on which our communities rely.
Renewable natural gas (RNG) can play a role in that effort.
Washington Eases Organics Contamination Limit in Proposed Rule
The Washington Department of Ecology released updated language in its proposal for its new organic materials management rules this week. The proposal is meant to set guardrails around the pre-processing of organic waste to prevent contamination in finished products like compost.
Industry Bodies Urge GHG Protocol to Account for Market Realities
A coalition of industry bodies is calling on the GHG Protocol, the world’s most widely used greenhouse gas accounting standard, to better account for market realities in its methodology. Under the GHG Protocol, the climate impact of biomethane depends on how the gas is produced, delivered, and claimed, taking into account lifecycle emissions. The groups argue that current guidance leaves many companies without a clear framework for market-based accounting, an issue with significant implications for how renewable natural gas and other low-carbon energy attributes are recognized and credited.
Power Sustainable Closes $45 Million Financing for Novilla RNG’s Dairy Renewable Natural Gas Platform
Power Sustainable Infrastructure Credit (PSIC) has closed a US$45 million senior secured financing for Novilla RNG, a nationwide developer, builder, owner, and operator of dairy renewable natural gas (RNG) projects. The financing will support growth capital expenditures, including the construction of two greenfield dairy RNG projects in South Dakota, as well as Novilla’s broader development pipeline. The deal underscores continued private capital momentum behind dairy-based renewable natural gas production across the United States.
Advances in Natural Gas Engine Technology Position RNG as a Practical Path for Heavy-Duty Fleets
A new generation of high-efficiency natural gas engines, paired with rapidly expanding renewable natural gas (RNG) infrastructure, is positioning natural gas as a commercially viable, performance-ready fuel for heavy-duty fleets. As diesel prices surge amid global market volatility, domestic RNG has remained relatively stable, widening the cost gap and reinforcing its value as a cost-control strategy for long-haul freight operators.
Produced from organic waste streams such as landfills, dairy farms and wastewater facilities, RNG is fully compatible with existing pipelines and fueling stations, allowing fleets to adopt it without new infrastructure. Backed by federal incentives like the Section 45Z Clean Fuel Production Credit and state low-carbon fuel programs, RNG supply has grown sharply in recent years, making it an already-available pathway to lower-emission, cost-effective heavy-duty transportation.
Sumitomo do Brasil and Cemvita Partner to Integrate RNG and Bio-Oil Production in Brazil
Sumitomo Corporation do Brasil and biotechnology company Cemvita have announced a partnership to integrate the production of renewable natural gas (RNG) and bio-oil, a precursor of sustainable aviation fuel (SAF), in Brazil. The collaboration pairs Cemvita’s biotechnology platform with Sumitomo’s global infrastructure and market access to convert waste streams into higher-value, lower-carbon fuels and accelerate commercialization in the country.
By integrating bio-oil technology with RNG projects, the partners aim to produce both fuels in parallel, creating operational and economic synergies while supplying waste-based feedstock for sustainable aviation fuel. The companies describe RNG as a strategic global commodity and position Brazil as a critical long-term hub for biofuel supply and the circular bioeconomy.
