Biomethane Could Be the Unsung Hero of the Energy Transition

In the fast-paced world of clean energy innovation, biomethane is rarely the star of the show. It doesn’t sparkle like solar, boom like batteries, or stir geopolitical intrigue like hydrogen. But quietly, consistently, and with increasing impact, biomethane is doing exactly what many climate technologies still promise to do someday: replacing fossil fuels today.

Produced from organic waste, agricultural residues, and even wastewater sludge, biomethane is essentially upgraded biogas with a methane content high enough to substitute fossil natural gas. It can be injected into existing gas grids, used in transport, or serve as a feedstock for chemicals and fertilizers. In a world scrambling to decarbonize gas use without rebuilding everything from scratch, biomethane is proving to be an invaluable bridge, and in some sectors, a long-term solution.

5 Ways to Cut Landfill Methane Pollution: How Local Governments Can Lead

Across the United States, there are more than 2,500 municipal solid waste landfills. As buried food scraps, yard clippings, and cardboard decompose in these landfills, they generate methane: a powerful greenhouse gas with more than 80 times the near-term warming potential of carbon dioxide. Beyond the significant warming impacts, landfills release hazardous air pollutants, pungent odors, and ozone precursors, which can harm the health and quality of life of neighboring communities. More than 36 million Americans live within three miles of a landfill.

For these communities, reducing landfill pollution is one of the most impactful and cost-effective ways to slow near-term warming while also improving air quality, protecting public health, and boosting the local economy. Local governments are well positioned to implement solutions. Many counties own and operate their local landfills and thereby have direct control over landfill design and management decisions, while others can advance best management practices through contracts with the private sector. In this article, we describe the top five opportunities to cut landfill methane pollution and the benefits of acting today.

Dairy Farm Turns Cow Manure into Clean-Energy Gold

Ash Grove Dairy, northwest of Lake Benton, Minn., is adding another revenue stream by turning manure produced by the 2,100-head Holstein cow herd into renewable natural gas via a methane digester that has been operational for about 18 months.

A joint venture between Clean Energy Fuels Corp. and bp called Renewco owns the digester facility, says Christie Ings, Clean Energy senior director of renewable natural gas engineering and compliance. “We are in partnership with the dairy, though, so there are royalties that are paid to the dairy for the renewable natural gas produced by the manure from Ash Grove’s dairy cows,” she says.

Republic Services Partners with EDL to Provide RNG for San Antonio Buses

EDL, an Australia-based producer of sustainable distributed energy, has announced Republic Services, Phoenix, and other key project stakeholders celebrated the third year of a partnership to provide sustainable solutions for San Antonio public buses at EDL’s Tessman Road renewable natural gas (RNG) facility.

Since commencing operations in 2022, EDL and Republic Services have worked with San Antonio-based partners including CPS Energy and Via Metropolitan Transit to support the city’s transition to a low-carbon future. The facility transforms methane-rich landfill gas into RNG that helps power Via’s fleet of compressed natural gas (CNG) buses, EDL says.

Canada’s Clean Fuel Credit Market in 2024: Expansion in Credits with Flat Volume Growth

On July 12th, 2025, Environment and Climate Change (ECCC) released the Clean Fuel Regulations (CFR) 2024 Quarterly Credit Market Report. Designed to reduce the life cycle carbon intensity of transportation fuels, the CFR credit system enables producers and importers to comply by generating or purchasing credits tied to low-carbon fuel supply and use in vehicles. This is the second edition of the report. The first was published in June 2024. cCarbon published the Canada CFR Data Release Analyst note based on the program data, offering a detailed analysis of the credit market trends.

Anew Climate and CNX Extend Exclusive Agreement to Advance Remediated Mine Gas as a Climate Solution

Anew Climate, LLC ("Anew"), a global provider of climate solutions, today announced the extension of its exclusive agreement with CNX Resources Corporation ("CNX") to market Remediated Mine Gas (RMG), a powerful ultra-low carbon intensity energy source derived from captured waste methane.

RMG is produced by capturing and upgrading waste gases from active and abandoned mines ("mine gas"). While federal regulations require mine gas (mainly methane, a greenhouse gas over 25 times more potent than CO2) to be released from mines for safety reasons, there are no regulations in place to mitigate its impact. This results in the release of untreated methane and other gases directly into the atmosphere, causing long-term environmental and emission impacts, as mine gas must be vented for decades after mining stops.
