SAF Act

Summary

SB 3759, the “Securing America’s Fuels Act” or “SAF Act,” would amend the Internal Revenue Code to restore a higher tax credit rate for sustainable aviation fuel (SAF) under the clean fuel production credit and extend that credit through December 31, 2033. The bill specifically reinstates a special rate calculation for SAF, increasing the credit from the general clean fuel rates to 35 cents per gallon for fuel produced at one type of qualified facility and $1.75 per gallon for another type of qualified facility. It also defines SAF for this purpose as liquid fuel used in aircraft that meets specified ASTM standards and is not derived from palm fatty acid distillates or petroleum. The bill would change federal tax law by amending section 45Z of the Internal Revenue Code, including conforming changes to related cross-references and the credit’s expiration date. Its provisions would apply to fuel produced after December 31, 2025, meaning the higher SAF credit would affect production beginning in 2026 and continue through 2033 if enacted. The measure is aimed at supporting domestic production and use of lower-carbon aviation fuels through tax incentives. The available context shows the bill was introduced and referred to the Senate Committee on Finance, with no recorded votes or committee transcript excerpts provided. As a result, there is no documented floor debate or committee testimony in the materials supplied. The introduction by a bipartisan group of senators suggests at least some cross-party interest in the policy. Because there are no transcripts or votes, there is little direct evidence of controversy in the provided record. The main policy issue likely centers on whether the federal government should continue and expand tax incentives for SAF, including the size and duration of the credit and the exclusion of certain feedstocks such as palm-derived inputs and petroleum. Supporters would likely view the bill as a way to accelerate aviation decarbonization and domestic fuel innovation, while any opposition would likely focus on tax expenditure costs, market distortion, or the environmental and eligibility standards used to define qualifying fuel.

Impact

The bill would amend section 45Z of the Internal Revenue Code to restore a special, higher clean fuel production credit rate for sustainable aviation fuel and extend the credit’s availability from December 31, 2029, to December 31, 2033. It would affect taxpayers and fuel producers that manufacture qualifying SAF after December 31, 2025, and would require the IRS and affected producers to apply the revised credit amounts and definitions in administering the clean fuel production credit.

Sentiment

The limited record suggests generally favorable or at least constructive sentiment toward the bill, as reflected by bipartisan sponsorship and the absence of recorded opposition, votes, or negative committee commentary in the materials provided. The measure appears to be framed as a pro-industry, pro-energy-security, and pro-decarbonization tax incentive, which typically attracts support from aviation, fuel, and clean-energy stakeholders. However, without hearing transcripts or vote data, the overall level of support cannot be measured precisely.

Contention

No specific points of contention are documented in the provided materials, but the likely areas of debate are the cost of extending a federal tax credit, the decision to give SAF a special higher rate instead of the general clean fuel rate, and the bill’s eligibility restrictions, including the exclusion of palm fatty acid distillates and petroleum-derived fuel. Stakeholders concerned about federal spending or tax preferences may question the subsidy’s duration and magnitude, while supporters are likely to emphasize emissions reductions, domestic supply development, and aviation sector competitiveness.

Farm to Fly Act of 2025This bill directs the Department of Agriculture (USDA) to integrate the advancement of sustainable aviation fuels into its programs.Specifically, this bill includes sustainable aviation fuel as an advanced biofuel for the purposes of several USDA bioenergy programs that primarily provide support and incentives for renewable energy projects.For purposes of these programs, the bill defines sustainable aviation fuel as liquid fuel, the portion of which is not kerosene, which (1) meets specific international standards, (2) is not derived from coprocessing specific materials (e.g., triglycerides) with a non-biomass feedstock, (3) is not derived from palm fatty acid distillates or petroleum, and (4) is certified as having a lifecycle greenhouse gas emissions reduction percentage of at least 50% compared with petroleum-based jet fuel (based on specific standards and agreements).In addition, the bill specifically includes fostering and advancing sustainable aviation fuels as part of the Biorefinery, Renewable Chemical, and Biobased Product Manufacturing Assistance Program.Further, USDA must carry out a comprehensive and integrated pursuit of all USDA mission areas for the advancement of sustainable aviation fuels, including throughthe identification of opportunities to maximize the development and commercialization of the fuels,supporting rural economic development through improved sustainability for aviation, andadvancing public-private partnerships.
