• The Trump administration is set to propose higher biofuel blending mandates for 2026 and 2027, prioritizing domestic production while restricting foreign feedstock eligibility.
  • The EPA may set actual quotas below industry expectations, sparking concerns from both biofuel producers and oil refiners.
  • Legislative moves, including the extension of the "45Z" Clean Fuel Production Credit, are expected to shape the economic and regulatory landscape for biofuels.

Draft Mandates Favor Domestic Biofuels

The Trump administration is finalizing draft biofuel blending mandates for 2026 and 2027, with plans to raise quotas for U.S.-produced biofuels while limiting eligibility for credits to North American feedstocks. The move aligns with the administration's "America First" energy strategy, aiming to reduce reliance on foreign supplies, particularly used cooking oil and tallow from Asia and South America. However, sources familiar with the matter suggest the EPA may set biomass-based diesel quotas below what industry advocates had hoped, potentially disappointing both biofuel and oil refining sectors.

Legislative and Market Implications

The House-passed extension of the "45Z" Clean Fuel Production Credit through 2031 adds another layer of complexity, as stakeholders await final Treasury regulations. Oil refiners and biofuel producers are locked in intense lobbying battles, with the former seeking flexibility for foreign feedstocks and the latter pushing for higher domestic quotas. Market participants are bracing for volatility in tradable credit markets, where billions of dollars are at stake.

"The administration’s focus on domestic sourcing could reshape trade flows and commodity markets," said one industry analyst, who asked not to be named due to the sensitivity of ongoing negotiations. Small biofuel producers, meanwhile, are wary of proposed changes to tax credit transferability, which could disadvantage firms without large tax liabilities.

Political and Industry Reactions

The draft mandates are expected to draw sharp reactions from both sides of the political aisle, with rural lawmakers likely to applaud the boost for U.S. farmers while environmental groups scrutinize the policy’s alignment with broader decarbonization goals. The aviation sector is also watching closely, as sustainable aviation fuel (SAF) producers assess whether the new rules will help or hinder their efforts to scale up production.

Final EPA and Treasury rules are still pending, leaving room for further negotiation—and uncertainty—in the months ahead.
