Renewable Fuel Annual Standards
The Clean Air Act requires EPA to set the RFS volume requirements annually. The annual standards are based on the statutory targets. EISA requires EPA to evaluate and in some cases adjust the standards.
EPA establishes the standards through a notice-and-comment rulemaking process with opportunity for public comment and stakeholder engagement.
- The Clean Air Act requires the standards be finalized by November 30th of the year preceding the compliance year.
- For the cellulosic standard, EPA sets cellulosic standard based on EIA projections, EPA’s own market assessment, and on information obtained from the notice and comment process.
- For the biomass-based diesel standard, EPA must determine the applicable volume of biomass-based diesel at least 14 months prior to the year in which the volume will be required.
EISA’s four renewable fuel standards are nested within each other. This means, the fuel with a higher GHG reduction threshold can be used to meet the standards for a lower GHG reduction threshold. For example, fuels or RINs for advanced biofuel (i.e., cellulosic, biodiesel or sugarcane ethanol) can be used to meet the total renewable fuel standards (i.e., corn ethanol).
The table below provides the annual volume standards that have been finalized for 2010 to 2018 (and the final biomass-based diesel volume for 2019), and proposed for 2019 (and the proposed biomass-based diesel volume for 2020).
