- Title
- Section 45Z Clean Fuel Production Credit
The proposed regulations would provide rules on the section 45Z clean fuel production credit as extended and modified by the One, Big, Beautiful Bill Act of 2025. Section 45Z provides a credit for clean transportation fuel produced domestically after December 31, 2024, and sold by December 31, 2029. The proposed regulations would address general requirements, such as credit eligibility, emissions rates, claim filing, and registration. The proposed regulations would also amend existing elective pay, credit transfer, and registration regulations for clarity and consistency. The proposed regulations would affect domestic fuel producers, credit claimants, and registrants.

- May 13, 2026IMAREAN CorpSupportBusiness📎 Attachment
KVASIR Intelligence™ / CMetricsGlobal / IMAREAN is a company providing intelligence and verification services for climate-smart agriculture. They support the proposed 45Z regulations but argue that the rules should specifically recognize a "two-signal" architecture that combines procedural documentation with independent informational signals (like satellite imagery) to verify agricultural practices. They advocate for a "verified lower-bound settlement" approach to ensure credit integrity and prevent adverse selection or principal-agent risks.
Read comment → - Apr 6, 2026Sievers Family Farms, LLCSupportBusiness📎 Attachment
Sievers Family Farms, LLC, a grain and beef cattle operation, supports the Section 45Z Clean Fuel Production Credit and its general framework. They advocate for specific technical updates to the 45ZCF-GREET model, including the use of species-specific emissions rates, accurate baseline manure management systems, and the inclusion of cellulosic biomass and food waste pathways.
Read comment → - Apr 6, 2026The Tax Law Center at NYU LawSupportAcademic📎 Attachment
The Tax Law Center at NYU Law, a public interest initiative, submitted comments regarding the proposed regulations for the Section 45Z Clean Fuel Production Credit. They support the proposed definitions for "production," "facility," and the exclusion of electricity as a "transportation fuel," while recommending that the credit should not provide benefits for climate-smart agriculture practices due to scientific uncertainty and lack of verification mechanisms.
Read comment → - Apr 6, 2026National Pork Producers CouncilOtherTrade association📎 Attachment
The National Pork Producers Council (NPPC) states that it cannot provide a meaningful position on the proposed 45Z regulations because the necessary analytical tools (the updated 45ZCF-GREET model and the USDA FD-CIC) have not yet been finalized or made available. They request that the Treasury withhold final action and reopen the comment period once these tools are published so that stakeholders can evaluate the real-world economic impacts.
Read comment → - Apr 6, 2026National Grain and Feed AssociationSupportTrade association📎 Attachment
The National Grain and Feed Association (NGFA) supports the proposed Section 45Z Clean Fuel Production Credit, provided it is implemented with operational feasibility and regulatory certainty. They specifically urge the Treasury to recognize USDA's Technical Guidelines for Crops used as biofuel feedstocks to provide clarity for farmers and supply-chain participants.
Read comment → - Apr 6, 2026Graphyte, Inc.SupportBusiness📎 Attachment
Graphyte, Inc., a carbon removal company, supports the Section 45Z clean fuel production credit and urges the Treasury and DOE to expand modeling tools to include Biomass Carbon Removal and Storage (BiCRS) technologies. They argue that current regulations risk excluding innovative carbon reduction methods and request that the Provisional Emissions Rate (PER) process be made more accessible to producers with materially different production pathways.

NATSO (Representing America’s Travel Centers and Truck Stops) and SIGMA (America’s Leading Fuel Marketers) are submitting a joint request to testify at a public hearing regarding the Section 45Z Clean Fuel Production Credit. They intend to discuss the need for mandatory credit value transparency and the incorporation of agricultural practices under the FD-CIC program.
Read comment → - Apr 6, 2026Minnesota Farmers UnionSupportUnion📎 Attachment
The Minnesota Farmers Union supports the proposed Section 45Z Clean Fuel Production Credit, noting its potential financial and environmental benefits for farmers. They advocate for updating the 45ZCF-GREET Model to include a wider variety of low-carbon feedstocks, innovative fertilizers like green ammonia, and the exclusion of biofuels produced from foreign feedstocks.
Read comment → - Apr 6, 2026Roeslein RenewablesSupportBusiness📎 Attachment
Roeslein Renewables expresses strong support for the proposed Section 45Z Clean Fuel Production Credit, particularly the provisions for negative emissions rates and species-specific emissions for manure-based RNG. The company urges the Department of Treasury and the Department of Energy to update the 45ZCF-GREET model with more accurate baseline emissions, species-specific carbon intensity scores, and additional production pathways like cellulosic biomass.
Read comment → - Apr 6, 2026Taxpayers for Common SenseOpposeAdvocacy📎 Attachment
Taxpayers for Common Sense (TCS) opposes the expansion of the 45Z clean fuel production credit, arguing that it increases costs for taxpayers and consumers while potentially subsidizing mature biofuels and creating wasteful spending. They urge the IRS to limit the credit's scope, implement rigorous verification for climate-smart agricultural practices, and establish clear guardrails to prevent fraud and abuse.
