Renewable Fuel Standard (RFS) Program: Standards for 2026 and 2027, Partial Waiver of 2025 Cellulosic Biofuel Volume Requirement, and Other Changes

Document 2026-06275 is a Final Rule published by the Environmental Protection Agency in the Federal Register on April 1, 2026, with an effective date of June 15, 2026. Under the Clean Air Act (CAA), the U.S. 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. The EPA is establishing the applicable volumes and percentage standards for 2026 and 2027 for cellulosic biofuel, biomass-based diesel (BBD), advanced biofuel, and total renewable fuel. The EPA is also partially waiving the 2025 cellulosic biofuel volume requirement and revising the associated percentage standard due to a shortfall in cellulosic biofuel production. Finally, the EPA is promulgating several regulatory changes to the RFS program, including removing renewable electricity as a qualifying renewable fuel under the RFS program (eRINs) and making minor revisions to the biogas provisions of the RFS program.
