RFA recommends improvements to 45Z regulations

The Renewable Fuels Association is urging the U.S. Treasury Department to quickly finalize regulations for the Section 45Z Clean Fuel Production Credit, saying continued delays are creating uncertainty for renewable fuel producers and investors. In testimony, RFA President and CEO Geoff Cooper said the tax credit has the potential to strengthen domestic energy production, support rural economies, and encourage innovation in renewable fuels and agriculture. “We believe that, if implemented effectively, the 45Z tax credit can stimulate domestic energy production, strengthen U.S. energy security, bolster rural economies, and drive innovation in the renewable fuels and agriculture industries,” Cooper said.

RFA also called for the immediate release of an updated 45ZCF-GREET emissions model reflecting changes required under last year’s One Big Beautiful Bill Act. Cooper said producers are already halfway through the 2026 tax year without the updated model needed to determine emissions rates and tax credit values.
