At a May 28, 2026 public hearing, fuel producers, agricultural stakeholders, and environmental credit companies testified before the U.S. Department of the Treasury (Treasury) and the Internal Revenue Service (IRS), calling for targeted fixes to proposed regulations affecting clean fuel production tax credit under Section 45Z of the Internal Revenue Code of 1986 (Section 45Z Credit).
Enacted by the Inflation Reduction Act and recently amended by the One Big Beautiful Bill Act (“OBBBA”), Section 45Z of the Internal Revenue Code offers a tax credit for the domestic production and sale of certain low-emission transportation fuels (“45Z Credit”). The 45Z Credit is worth $0.20 (or $1.00 for producers meeting prevailing wage and apprenticeship requirements) per gallon of renewable diesel, sustainable aviation fuel (“SAF”), renewable natural gas (“RNG”), and certain other low-carbon fuels produced domestically and sold.
