Higher biofuel volumes strengthen demand for corn soybeans and diesel fuels
The U.S. Environmental Protection Agency has finalized Renewable Fuel Standard requirements for 2026 and 2027, setting the highest renewable fuel volumes since the program began. The rule increases overall biofuel demand while keeping ethanol volumes stable, offering stronger market confidence for farmers and fuel producers.
Under the rule, total renewable fuel volumes are set at 26.81 billion gallons for 2026 and 27.02 billion gallons for 2027. Much of the growth is focused on advanced biofuels, including biomass-based diesel and cellulosic fuels. Renewable fuels are made from agricultural feedstocks such as corn, soybeans, used cooking oil, and animal fats.
The conventional ethanol requirement remains at 15 billion gallons. Ethanol remains a major use for U.S. corn, helping maintain steady demand. Wider approval of year-round E15 fuel sales could further support corn markets by allowing higher ethanol blends throughout the year.
Biomass-based diesel volumes increase to 8.86 billion gallons in 2026 and 8.95 billion gallons in 2027, with even higher levels after adjustments for small refinery exemptions. These fuels rely heavily on soybean oil, supporting demand for soybeans and strengthening price opportunities for growers.
The rule also reforms how small refinery exemptions are handled. Volumes that were previously waived are redistributed into future obligations, ensuring total renewable fuel demand is preserved. This change helps reduce uncertainty that has affected agricultural and biofuel markets for years.
EPA did not finalize limits on imported fuel credits under this rule. Instead, the agency plans to address import-related Renewable Identification Numbers starting in 2028, allowing more time for review.
Overall, the final rule reinforces the role of American agriculture in renewable fuel production. By setting strong targets and improving program stability, the policy provides farmers with clearer demand signals for corn, soybeans, and other biofuel feedstocks.
