Treasury, IRS Finalize 45Z Clean Fuel Credit Rules, Boosting Pivot Bio’s Regenerative Agriculture Play
Event summary
- Treasury and IRS formalized integration of USDA’s Feedstock Carbon Intensity Calculator into the 45Z Clean Fuel Production Tax Credit on September 8, 2026.
- DOE released an updated 45ZCF-GREET model incorporating the USDA calculator, enabling immediate credit claims for ethanol producers using regenerative agriculture practices.
- Pivot Bio’s nitrogen-fixing microbial products (PROVEN® G3) qualify under the new rules, lowering carbon intensity scores for corn feedstock.
- Guidance covers fuel produced in 2025 and 2026, with transition accommodations for early adopters.
The big picture
The finalization of 45Z guidance aligns key U.S. agencies on regenerative agriculture’s role in clean fuel production, creating a direct financial incentive for farmers to reduce synthetic nitrogen use. This marks a strategic shift in biofuel policy, prioritizing on-farm carbon intensity reductions—a tailwind for agtech players like Pivot Bio. The move could reshape competitive dynamics in the biofuels sector, favoring producers with access to low-carbon feedstocks.
What we're watching
- Adoption Pace
- How quickly ethanol producers and farmers will integrate Pivot Bio’s products to capitalize on the 45Z credit.
- Regulatory Clarity
- Whether the final 45Z rule, expected later in 2026, will introduce material changes to current guidance.
- Market Impact
- The extent to which the 45Z credit accelerates regenerative agriculture adoption beyond corn feedstock.
