Proposed Renewable Fuel Standards for 2026 and 2027
On this page:
Rule Summary
On June 13, 2025, EPA announces a proposed rule to establish required Renewable Fuel Standard volumes and percentage standards for 2026 and 2027, as well as to partially waive the 2025 cellulosic biofuel volume requirement and revise the associated percentage standard due to a shortfall in cellulosic biofuel production. The proposed volume requirements are listed below.
| Proposed Volume Requirements (billion RINs)a | 2025 | 2026 | 2027 |
|---|---|---|---|
| Cellulosic biofuel | 1.19 | 1.30 | 1.36 |
| Biomass-based diesel | n/a | 7.12 | 7.50 |
| Advanced biofuel | n/a | 9.02 | 9.46 |
| Renewable fuel | n/a | 24.02 | 24.46 |
a One RIN is equivalent to one ethanol-equivalent gallon of renewable fuel.
EPA is also 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).
Additional regulatory changes in several areas to strengthen our implementation of the RFS program are also included in the proposed rule.
Public Hearing
EPA held a virtual public hearing on July 8, 2025, for the proposed rule.
