Key Takeaways
- USDA Secretary Brooke Rollins has announced the final Regenerative Feedstock Rule, establishing a voluntary framework connecting on-farm regenerative practices to premium markets within the US biofuel supply chain.
- The rule covers four feedstock crops — corn, soybeans, sorghum, and spring canola — and introduces field-level carbon intensity quantification, mass balance chain-of-custody standards, traceability requirements, and auditing and verification protocols.
- USDA is releasing an updated Feedstock Carbon Intensity Calculator (FD-CIC) to help producers quantify the impact of cover crops, improved nutrient management, and conservation tillage, with outputs usable when marketing feedstocks to participating biofuel producers.
- Approximately 68% of US corn farmers and 70% of US soybean farmers already implement at least one regenerative practice, representing a large addressable base for the new market pathway.
- The Feedstock Rule builds on USDA's existing Regenerative Pilot Programme, which has committed $700 million, completed 67,000+ whole-farm conservation plans, and covered more than 49 million acres.
USDA Releases Final Regenerative Feedstock Rule for Biofuel Markets
USDA Secretary Brooke Rollins has announced the final Regenerative Feedstock Rule, a new regulatory framework that creates a voluntary market pathway for American farmers who implement regenerative agriculture practices to access premium pricing within the US biofuel supply chain. The rule was announced on June 25, 2026, the same day President Trump signed an Executive Order advancing regenerative and precision agriculture at the federal level.
The Feedstock Rule applies to four covered crops: corn, soybeans, sorghum, and spring canola. Rather than establishing mandates, the framework creates a market mechanism through which producers who voluntarily adopt defined regenerative practices can demonstrate and monetise the resulting reduction in their crop's carbon intensity when selling to participating biofuel producers.
What the Rule Establishes
The Regenerative Feedstock Rule introduces five core components: coverage definitions for biofuel feedstock crops and participating supply chain entities; field-level quantification of crop-specific carbon intensity; mass balance chain-of-custody standards covering traceability and recordkeeping; auditing and verification requirements; and regenerative agriculture practice standards for each covered crop.
To support producer participation, USDA is simultaneously releasing an updated Feedstock Carbon Intensity Calculator (FD-CIC). The tool allows producers to quantify the carbon intensity impact of specific practices including cover crops, improved nutrient management, and conservation tillage — including no-till and reduced tillage. The outputs can be used directly when marketing eligible feedstocks to biofuel producers, creating a data-verified link between on-farm practice adoption and market access.
“Today's USDA Regenerative Feedstock Rule put farmers, not Washington bureaucrats, in the driver's seat. Instead of mandates, we're creating market opportunities. Farmers who choose to implement regenerative practices will have new opportunities to earn premium prices, lower their input costs, improve soil health, and strengthen the long-term profitability of their operations,” said Brooke Rollins, Secretary of Agriculture.
Scale of the Market Opportunity
USDA estimates the addressable market as substantial. Around 6 billion bushels of US corn are used for ethanol production annually, with 68% of corn farmers already implementing at least one regenerative practice. Approximately 1.8 billion bushels of soybeans are produced for biofuel, with 70% of soybean farmers already using at least one such practice. The rule formalises a pathway for that existing adoption to generate measurable market value.
The Feedstock Rule builds on USDA's Regenerative Pilot Programme, which has committed $700 million to help producers adopt soil health and water quality practices. That programme has already completed more than 67,000 whole-farm conservation plans covering over 49 million acres and entered more than 1,500 conservation contracts worth more than $200 million.
