Restoring Fuel Market Freedom Act of 2025 Repeals Key Alternative Fuel Tax Credits for Biodiesel, Ethanol, and Sustainable Aviation Fuel

The Restoring Fuel Market Freedom Act of 2025 is a surgical strike on the tax incentives currently supporting the alternative fuel industry. This bill systematically repeals the Alcohol Fuels Credit (Section 40), the Biodiesel Fuels Credit (Section 40A), the Sustainable Aviation Fuel Credit (Section 40B), and the Clean Fuel Production Credit (Section 45Z). Beyond just cutting the checks, the legislation also eliminates registration requirements for producers of second-generation biofuels and sustainable aviation fuels under Section 4101. These changes take effect immediately for all fuel produced, sold, or used after the date the bill is signed into law, effectively pulling the financial rug out from under the renewable fuel market overnight.

The End of the Subsidy Era

By repealing Sections 40 and 40A, this bill removes the primary tax breaks that have helped ethanol and biodiesel stay price-competitive with traditional gasoline and diesel. For a truck driver or a farmer using biodiesel blends, this could mean a direct hit to the wallet if producers pass the lost tax savings—often around $1.00 per gallon for biodiesel—straight to the pump. The bill also strikes Section 6426, which provided excise tax credits for fuel mixtures. This isn't just a paperwork change; it’s a fundamental shift in the economics of the local gas station, potentially making 'green' fuel options more expensive or harder to find as the financial incentive to blend them disappears.

Grounding Sustainable Flight

If you’ve noticed airlines touting 'sustainable aviation fuel' (SAF) to lower their carbon footprint, that trend might be headed for a nosedive. Section 4 of the bill repeals the Section 40B credit specifically designed to help the aviation industry transition away from standard jet fuel. Without this credit, the high cost of producing SAF becomes a much heavier burden for airlines. For the average traveler, this could translate into higher ticket prices if airlines try to maintain their environmental targets without federal tax support, or it could simply mean a return to total reliance on traditional petroleum-based jet fuel.

Cutting the Cord on Clean Production

The bill also targets the future of fuel manufacturing by repealing the Section 45Z Clean Fuel Production Credit. This credit was designed to reward facilities based on how low their emissions are, but under Section 5 of this Act, that incentive is gone. For a small business owner or an investor in a startup biofuel plant, the removal of 'direct payment' options under Section 6417(b)(9) means they can no longer get cash back from the IRS for their production levels. By stripping away these credits and the associated registration rules, the bill moves the market back to a 'fossil fuels first' landscape, favoring established oil and gas infrastructure over the newer, more expensive renewable alternatives.
