Biofuels stakeholder groups submitted comments to the Environmental Protection Agency last week on the agency’s proposed Renewable Fuel Standard volumes for 2026 and 2027.

American Coalition for Ethanol (ACE) CEO Brian Jennings expressed support for the proposed record volumes, while noting a few targeted changes to ensure the policy continues to fulfill its mission of increasing the use of American-made biofuels.

“ACE supports EPA proposing the highest RVOs to date, including more than 24 billion gallons of total renewable fuel for 2026 and 2027,” said Jennings in written comments. “We applaud EPA for proposing to significantly increase advanced biofuel levels, so those gallons are not displacing corn ethanol in the conventional biofuel pool.”

While supporting many aspects of the proposed rule, ACE urged EPA to consider setting conventional biofuel volumes above 15 billion gallons to offset export market losses and maximize the blending of physical gallons of ethanol and recognize higher projected use of E15 and E85, particularly given several state-level E15 year-round approvals, record E85 sales in California, and bipartisan legislation pending in Congress to permanently allow E15 sales nationwide.

Clean Fuels Alliance America – representing biodiesel, renewable diesel, and sustainable aviation fuel – also expressed appreciation for EPA’s intent to provide consistent RFS growth in recognition of the industry’s investments in new capacity.

EPA proposes biomass-based diesel and advanced biofuel volumes to reach 5.61 billion gallons in 2026 – more than two billion gallons higher than in 2025. “The proposal is a welcome signal to U.S. farmers and biofuel producers, and we are ready to meet these higher volumes with domestically produced fuel,” Clean Fuels writes in its comments. “We ask that the final rule sustain the volumes as proposed to ensure that our capacity is fully utilized. These volumes are readily achievable, based on current domestic production and investments that have been made.”
