Final Renewable Fuels Standards Rule for 2023, 2024, and 2025

Rule Summary
On June 21, 2023, EPA announces a final rule to establish biofuel volume requirements and associated percentage standards for cellulosic biofuel, biomass-based diesel (BBD), advanced biofuel, and total renewable fuel for 2023–2025. The rule also responds to a court remand of the 2016 annual rule by establishing a supplemental volume requirement of 250 million gallons of renewable fuel for 2023. The final volume targets are as follows:
2023 | 2024 | 2025 | |
---|---|---|---|
Cellulosic biofuel | 0.84 | 1.09 | 1.38 |
Biomass-based dieselb | 2.82 | 3.04 | 3.35 |
Advanced biofuel | 5.94 | 6.54 | 7.33 |
Renewable fuel | 20.94 | 21.54 | 22.33 |
Supplemental standard | 0.25 | n/a | n/a |
a One RIN is equivalent to one ethanol-equivalent gallon of renewable fuel.
b BBD is given in billion gallons.
This final rule includes steady growth of biofuels for use in the nation’s fuel supply for 2023, 2024, and 2025. The Energy Independence and Security Act (EISA) of 2007 does not specify statutory volumes after 2022, and EPA in this rule is establishing final biofuel volume targets for all categories under the “set” authority. When determining biofuel volumes for years after 2022, EPA must consider a variety of factors specified in the statute, including costs, air quality, climate change, implementation of the program to date, energy security, infrastructure issues, commodity prices, water quality, and supply.
