Bipartisan group of 18 Senators call on EPA to raise volumes for 2026 RFS

In Washington, a bipartisan group of 18 Senators, led by Sens. Amy Klobuchar (D-MN) and Chuck Grassley (R-IA), sent a letter to EPA Administrator Michael Regan encouraging the agency to complete 2026 RFS rules and raise volumes for biomass-based diesel and advanced biofuels to levels that are consistent with production and availability. The letter points to the discouraging market signal EPA sent with the 2023-2025 volumes and the negative impact on local economies and jobs in the clean fuels industry.

“America’s environmental and energy security depend on the widespread production, availability, and use of biofuels. Biofuels play a particularly critical role in emissions reduction for heavy-duty transportation — including aviation, shipping, rail, and trucking — while opening up economic opportunities for American farmers,” the Senators wrote. “A strong RFS and broad availability of homegrown agricultural feedstocks bolster the domestic fuel supply and are critical for ensuring we keep up the progress we have made in decarbonizing our roads, seas, railways, and skies.”

“Iowa businesses are bearing the consequences of the Biden EPA’s 2023 rule that set extraordinarily low RFS volumes. To give you an example of the impacts, a plant in Ralston was forced to shut down as a result, which cost local jobs and hurt Iowa families,” Grassley said. “The EPA ought to embrace biofuels by correcting its past mistake and increasing 2026 levels in line with market data. Our producers are ready to supply communities with clean, bio-based fuels — if only the federal government would help facilitate their work rather than institute burdens.”
