Clean Fuels Urges President Trump to Quickly Finalize RFS, 45Z Rules

Jan 27, 2026

Clean Fuels Alliance America sent a letter to President Donald Trump highlighting the biodiesel, renewable diesel and SAF industry’s contribution to U.S. energy security and rural prosperity, as the President embarks on visits across the country to highlight economic conditions. The letter emphasizes that the industry’s continued growth is at risk as farmers and fuel producers await regulatory rules – specifically, the Renewable Fuel Standards for 2026 and 2027 and rules for the Section 45Z Clean Fuel Production Credit – that were due under the prior administration.

“As you visit Iowa this week and other American cities in the coming weeks, Clean Fuels and its members would like to draw your attention to the potential of America’s biodiesel, renewable diesel, and SAF industry,” Clean Fuels writes. “Our industry has made substantial investments to meet America’s demand for energy security and rural economic prosperity.”

“Our progress is threatened by delays in policy decisions that should have been made by the preceding administration. We anticipate that you will quickly finalize these policies and secure your promise as the most pro-biofuel president in history,” the letter continues.

Last week, the administration completed interagency review of proposed rules for the 45Z Clean Fuel Production Credit – the final step before public release and a comment period.
