DOE rescinds unused cellulosic biofuels production incentive framework

The U.S. Department of Energy (DOE) has published a final rule rescinding the regulatory framework for production incentives for cellulosic biofuels, eliminating an inactive program that Congress never funded. The rule, issued by the Office of Critical Minerals and Energy Innovation (formerly the Office of Energy Efficiency and Renewable Energy), takes effect on October 1, 2026, and was published in the Federal Register of September 1, 2026.

The action removes 10 CFR part 452 in its entirety, the Cellulosic Biofuels Production Incentive regulations, which DOE describes as outdated and no longer aligned with its strategic priorities or the prevailing energy policy framework. The rule is designated an E.O. 14192 deregulatory action because it reduces administrative burden by eliminating an inactive regulatory framework.

An unused program

The Cellulosic Biofuels Production Incentive program was originally established under the authority of section 942 of the Energy Policy Act of 2005 (Pub. L. 109–58), codified at 42 U.S.C. 16251, to provide production incentives for cellulosic biofuels. However, Congress never appropriated funds to DOE to implement the program, leaving it unused since its inception.

• The program was intended to award production incentives to the lowest bidder in a reverse auction.
• DOE determined the rescission is strictly procedural under 10 CFR part 1021, appendix A, paragraph A6.
• No new requirements or burdens are imposed on any entity, including small businesses.

The Renewable Fuel Standard takes over

DOE notes that the landscape for biofuels incentives has evolved since the program’s creation. The Renewable Fuel Standard (RFS), administered by the Environmental Protection Agency (EPA), has become the primary federal mechanism to incentivize the production of renewable fuels, including cellulosic biofuels, through Renewable Identification Numbers (RINs).

The rule follows a notice of proposed rulemaking published on May 16, 2025 (90 FR 20942). DOE received one comment in response, from an individual, who argued the action required a full environmental assessment or impact statement under the National Environmental Policy Act (NEPA). DOE rejected that view, concluding that rescinding an inactive program with no ongoing environmental impacts does not constitute a major federal action warranting further review.

Regulatory review and impact

The rule was reviewed by the Office of Information and Regulatory Affairs (OIRA) of the Office of Management and Budget (OMB) and determined to be a “significant regulatory action” under section 3(f) of Executive Order 12866. DOE certified under the Regulatory Flexibility Act that the rule would not have a significant economic impact on a substantial number of small entities, and it imposes no new information collection requirements under the Paperwork Reduction Act.

For affected biofuel producers, the final rule removes the regulatory burden of an inactive incentive program, allowing them to focus resources on the RFS framework that now governs renewable fuel production. The contact for the rulemaking is Dr. Valerie Reed of the DOE’s Alternative Fuels and Feedstocks Office.
