Fuels Parity Act

HR 3337, the Fuels Parity Act, removes a prohibition that previously excluded corn starch ethanol from being counted as "advanced biofuel" under the Clean Air Act. This change directly affects corn-based ethanol producers by allowing corn starch ethanol to qualify under renewable fuel standards. The bill also requires the EPA to update its methodology for calculating greenhouse gas emissions from corn-based ethanol and biomass-based diesel every five years, starting 90 days after enactment, with the first update mandating the use of the Argonne National Laboratory's GREET model. These provisions aim to standardize how emissions are assessed for these fuels under federal renewable fuel programs.
