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.
One of Canada’s First RNG Plants Now Fully Operational in Blenheim, Ontario
One of the first renewable natural gas (RNG) plants in Canada is now fully operational in Blenheim, Ontario. The $100-million facility, built by Waste Connections with support from Enbridge Gas at the Ridge Landfill, captures landfill gas generated by decomposing waste and converts it into carbon-neutral, pipeline-quality RNG. The clean gas is injected into the natural gas distribution system, supplying roughly 18,000 homes and businesses, or about 40 percent of Chatham-Kent.
Project officials say the plant has run smoothly since being commissioned, recently reaching 98 percent uptime. The facility removes oxygen, nitrogen dioxide, carbon dioxide and other compounds before injecting clean gas into the pipeline, and it is expected to offset more than 110,000 tonnes of greenhouse gas emissions per year, supporting Ontario’s 2030 climate goals.
Archaea Energy and Republic Services Celebrate First RNG Plant in Landmark Partnership
Archaea Energy, a subsidiary of bp, and Republic Services have marked the opening of the first renewable natural gas plant under their Lightning Renewables joint venture, which is slated to include roughly 40 RNG projects in total. Located in Fort Wayne, Indiana, the facility captures landfill gas generated by the decomposition of waste at a Republic Services site and converts it into pipeline-quality RNG.
The plant uses a modular, skid-based design that allows for faster construction than traditional custom-built RNG facilities. Once fully operational, it is expected to process up to 6,400 standard cubic feet per minute of gas, enough to heat more than 25,000 homes annually, according to the U.S. EPA, while supporting local air quality and expanding domestic energy production.
Casella Waste Systems and Waga Energy Unveil RNG Facility at Ribbon Cutting
Casella Waste Systems and Waga Energy held a ribbon-cutting ceremony to mark the opening of a renewable natural gas production facility at the Chemung County Landfill in Elmira, New York. The plant has been converting landfill gas into RNG since January 2026 and uses Waga Energy’s patented WAGABOX technology to upgrade the gas to pipeline quality, which is then injected directly into the Valley Energy distribution network.
The facility is designed to generate up to 610,000 MMBtu of renewable gas per year and is expected to avoid more than 47,000 tons of CO2-equivalent emissions annually, according to EPA standards. In its first year, it is projected to produce 340,000 MMBtu, equivalent to roughly 2.4 million gallons of diesel fuel. Casella leaders described the project as a key example of partnering with specialists to create value from waste.
