British Columbia wins regulatory victory for the biogas industry; GFL, Waga and others release latest RNG updates
The British Columbia Utilities Commission (BCUC) confirmed that utilities can include the purchase of renewable natural gas (RNG) credits in their decarbonization strategies, securing a key regulatory victory for the biogas industry that relies on such regulatory frameworks. This monthly report also summarizes the latest industry developments, including GFL and Opal Fuels building new RNG facilities in two locations, Casella and Waga starting operations at a new plant in New York State, Mobius Renewables acquiring Air Liquide's biogas asset portfolio, and Constellation Energy's minority equity investment in Pine Creek RNG.
This article is the latest installment in Waste Dive's Biogas Monthly series.
The British Columbia Utilities Commission (BCUC) confirmed that utilities can purchase renewable natural gas (RNG) credits as part of their decarbonization strategies. The ruling is a win for the biogas industry, which relies heavily on such regulatory structures.
The so-called book-and-claim mechanism allows utilities looking to reduce the carbon impact of fossil gas in their pipelines to fund landfill and anaerobic digestion RNG projects elsewhere in North America and count the resulting RNG toward their own systems. Biogas industry groups support such mechanisms because they expand the potential pool of investors for RNG projects, similar to the logic of the broader carbon offset industry.
The issue before the BCUC involved a provincial target requiring utilities to source 15% of their total gas volume from RNG facilities by 2030. Alex Ripley, government affairs manager for RNG Coalition Canada, said the target has been a catalyst for increased RNG contracts, in part because of the flexibility utilities have in acquiring credits.
"This is the basis on which RNG is traded in North America and in most of the world," Ripley said.
This year, RNG targets for utilities in Canada have shifted due to competing priorities. In April, the Quebec government proposed delaying the deadline for utility Énergir to source 10% of its gas volume from RNG to 2032, two years later than originally planned.
The utility was expected to reach 5% this year, but customers have complained about shouldering rising costs associated with the procurement. According to Canada's National Observer, Quebec estimated the delay would save customers between C$130 million and C$155 million in 2030.
British Columbia's RNG target is voluntary. Currently, about 3% of the gas supply purchased by the province's main utility, FortisBC, is RNG.

GFL and Opal Fuels partner on two landfill projects
GFL Environmental and Opal Fuels announced they will develop RNG facilities at two sites: the Stones Throw Landfill in Tallapoosa County, Alabama, and the Grady Road Landfill in Polk County, Georgia. The projects will be jointly owned by the two companies and are expected to produce nearly 2 million mmBtu of RNG annually.
The on-site purified RNG will be distributed through Opal's fuel systems for use in transportation. The fuel marketer and distributor expects the fuel produced at the two sites to supply about 800 heavy-duty tractors.
"Adding RNG production capacity at a time when fleet demand is accelerating further validates the strength of our vertically integrated model—connecting landfill partners to high-value end markets through an expanding network of fueling stations," Opal Fuels co-CEO Jonathan Maurer said in a statement.
GFL is continuing to build out RNG facilities across its landfill portfolio. During its most recent earnings call in May, CFO Luke Pelosi said five such facilities are currently operating, with four more slated to come online in 2027 and 2028, respectively.
Casella and Waga bring new landfill facility online
Waga Energy has completed construction of an RNG facility at the Chemung County Landfill in Elmira, New York, which is operated by Casella Waste Systems. Waga fully funded the facility's construction and plans to own and operate it for 20 years, sharing RNG sales revenue with Casella.
The facility can produce up to 610,000 mmBtu of RNG annually, with first-year production expected at 340,000 mmBtu. RNG produced on site will be injected into Valley Energy's natural gas distribution network.
Since EQT Infrastructure acquired a majority stake in Waga in September, the company has continued to expand its portfolio of landfill RNG projects. Waga currently operates 36 RNG production facilities in France, Spain, Canada, and the United States, with 19 more under construction.
Casella is also working with Waga at the Hyland Landfill in Angelica, New York. The company typically partners with third-party developers, including Archaea Energy and Viridi Energy, on RNG projects tied to its landfills. During its first-quarter earnings call in May, CEO Ned Coletta said the strategy has produced "mixed results" overall, but the Waga projects "seem to be operating very well."
Investor-backed startup acquires Air Liquide biogas assets
Mobius Renewables, a biogas platform established in December by Australian asset manager IFM Investors, has acquired Air Liquide's biogas production portfolio, including six landfill gas-to-RNG facilities in the United States, assets in France, and controlling stakes in facilities in Norway and Sweden.
Mobius, headquartered in Houston, also includes in its portfolio assets from GreenGasUSA, which IFM acquired in 2023. GreenGas focuses on RNG produced primarily from wastewater systems through anaerobic digestion.
Air Liquide, whose U.S. headquarters are in Houston, has a long history of working with the landfill industry. The company developed proprietary technology for separating carbon dioxide from landfill gas, enabling its facilities to purify the gas into pipeline-grade RNG. It has also partnered with Waga Energy at several facilities.
The combined U.S. portfolio can produce up to 5.5 million mmBtu of RNG annually.
"With this transaction, our team can now focus on improving operations and investing in new projects, laying the groundwork for future global growth," Mobius CEO Cynthia Walker said in a press release.
Constellation Energy invests in Pine Creek RNG
Baltimore-based energy supplier Constellation Energy announced a minority equity investment in five RNG facilities owned and operated by Pine Creek RNG. The agreement allows Pine Creek to develop a new batch of facilities that can deliver approximately 3 million mmBtu of RNG annually, with Constellation handling marketing.
The existing portfolio includes three facilities at public landfills in Washington, Utah, and Iowa, a facility at a landfill owned by Waste Connections in Illinois, and a facility in Washington processing agricultural waste. Together, these facilities can produce about 1.5 million mmBtu of RNG annually. Pine Creek, a private company, is headquartered in St. Petersburg, Florida.
Constellation has a history of incorporating RNG into its fuel mix. In 2019, it partnered with Aria Energy to market RNG produced at a Waste Connections landfill in Nebraska. In 2021, it also announced a 10-year agreement with American Natural Gas to supply RNG to its nationwide network of natural gas fueling stations, with fuel sourced through an agreement with project developer The Landfill Group.
