The "Farmer First Fuel Incentives Act" proposes several significant changes to the clean fuel production credit under the Internal Revenue Code. A primary provision mandates that any fuel qualifying for this credit must be derived from feedstocks produced or grown within the United States , aiming to support domestic agriculture and production. This requirement applies to transportation fuel sold after December 31, 2024. Furthermore, the bill modifies how emissions rates are determined for the credit by explicitly requiring the exclusion of indirect land use change (ILUC) from lifecycle greenhouse gas emissions calculations. This adjustment, to be based on Secretary-determined regulations in consultation with EPA and USDA, will apply to emissions rates published for taxable years beginning after December 2025. Finally, the legislation extends the clean fuel production credit from its current expiration date of December 31, 2027, to December 31, 2034, and increases the precision of the emissions factor rounding from 0.1 to 0.01.
