🌱EPA Proposes Renewable Fuel Standards Changes for 2026 and 2027
On June 17, 2025, the U.S. Environmental Protection Agency (EPA) proposed volumes and percentage standards for four categories of renewable fuel that would apply to obligated parties in 2026 and 2027 under the Renewable Fuel Standard (RFS) program. On August 22, 2025, the EPA issued decisions on 175 small refinery exemption (SRE) petitions under the RFS program. This supplemental proposal takes into consideration the expected impacts of the SRE decisions issued. Based on this information, the EPA is co-proposing additional volumes in 2026 and 2027 representing complete (100 percent) reallocation and 50 percent reallocation for SREs granted in full or in part for 2023 and 2024, as well as those projected to be granted for 2025, as part of the ongoing RFS rulemaking. The EPA is also providing more information on its projection of SREs to inform the calculation of the 2026 and 2027 percentage standards.

EPA is partially waiving the 2024 cellulosic biofuel volume requirement and revising the associated percentage standard under the Renewable Fuel Standard (RFS) program due to a shortfall in cellulosic biofuel production. This action also makes a minor revision to the biogas provisions of the RFS program.
Learn More🌱Proposed RFS Changes for 2026 and 2027
Under the Clean Air Act (CAA), the Environmental Protection Agency (EPA) is required to determine the applicable volume requirements for the Renewable Fuel Standard (RFS) for years after those specified in the statute. EPA is proposing the applicable volumes and percentage standards for 2026 and 2027 for cellulosic biofuel, biomass-based diesel (BBD), advanced biofuel, and total renewable fuel. EPA is also proposing to partially waive the 2025 cellulosic biofuel volume requirement and revise the associated percentage standard due to a shortfall in cellulosic biofuel production. Finally, EPA is proposing several regulatory changes to the RFS program, including reducing the number of Renewable Identification Numbers (RINs) generated for imported renewable fuel and renewable fuel produced from foreign feedstocks and removing renewable electricity as a qualifying renewable fuel under the RFS program (eRINs).
