Final Renewable Fuel Standards for 2026 and 2027
On this page:
Rule Summary
On March 27, 2026, EPA announces a final rule to establish required Renewable Fuel Standard volumes and percentage standards for 2026 and 2027, which include 70 percent reallocation of small refinery exemptions granted for 2023–2025. This rule also partially waives the 2025 cellulosic biofuel volume requirement and revises the associated percentage standard due to a shortfall in cellulosic biofuel production. The final volume requirements, SRE reallocation volumes, and total applicable volumes are listed below.
| RFS Standard | Volume Requirement | SRE Reallocation Volume | Total Applicable Volume | ||||
|---|---|---|---|---|---|---|---|
| 2025 | 2026 | 2027 | 2026 | 2027 | 2026 | 2027 | |
| Cellulosic biofuel | 1.21 | 1.36 | 1.43 | 0 | 0 | 1.36 | 1.43 |
| Biomass-based diesel | n/a | 8.86 | 8.95 | 0.21 | 0.25 | 9.07 | 9.20 |
| Advanced biofuel | n/a | 10.82 | 10.98 | 0.28 | 0.34 | 11.10 | 11.32 |
| Renewable fuel | n/a | 25.82 | 25.98 | 0.99 | 1.04 | 26.81 | 27.02 |
EPA is also finalizing several regulatory changes to the RFS program, including 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 final rule.
