Washington D.C. - The U.S. House of Representatives on May 13, 2026, approved legislation allowing the year-round sale of gasoline blended with 15% ethanol, known as E15. This move, framed by proponents as a boon for consumers and farmers, marks a significant policy shift long sought by the biofuels industry.
The passage of the Nationwide Consumer and Fuel Retailers Choice Act on May 13, 2026, signifies a critical juncture for the American biofuels sector, aiming to expand market access for ethanol and potentially influence fuel prices.
The vote occurred after considerable negotiation among Republican factions. Originally slated for inclusion in the farm bill, the E15 provision was separated for a standalone vote on the House floor. This decoupling followed promises from GOP leadership to farm-state Republicans that the measure would receive a vote, a commitment that encountered resistance from some hardliners within the party.

Industry and Political Support
A coalition of biofuel refiners, the Sustainable Advanced Biofuels Refiners Coalition, publicly backed the legislation, aligning with agricultural and biofuel organizations that had lobbied for its passage. Leaders from these sectors gathered on Capitol Hill the day prior to the vote, underscoring the policy's prominence, particularly with the 42nd annual International Fuel Ethanol Workshop & Expo (FEW) coinciding with these developments.
Several Iowa Republican lawmakers, including Representatives Feenstra, Miller-Meeks, and Zach Nunn, championed the bill. They framed it as a victory for Iowa farmers and American consumers seeking lower fuel costs and greater market certainty for agricultural products. Representative Nunn reportedly engaged directly with House Speaker Mike Johnson on the chamber floor to ensure the measure reached a vote.
Stated Aims and Lingering Questions
Supporters argue that year-round E15 sales will provide American consumers with lower-cost fuel options and expand markets for U.S. farmers. The White House has previously indicated support for year-round E15, with both President Donald Trump and Vice President JD Vance reportedly assuring farmers of progress on the issue in separate appearances earlier in the year.

However, not all perspectives are uniformly positive. Concerns have been raised regarding the long-term impacts of increased corn usage for ethanol production, potentially affecting the availability and cost of animal feed. Furthermore, questions persist about the actual extent to which E15 will depress consumer gas prices, a stated goal of related governmental actions.
The U.S. Environmental Protection Agency (EPA) had previously taken steps, on March 26, 2026, to temporarily allow wider sales of higher-ethanol blends. This action was partly in response to soaring gas prices. At that time, officials acknowledged potential risks associated with higher ethanol levels, citing possible corrosion issues for older vehicles, boats, and all-terrain vehicles. Some analyses also questioned the efficacy of such measures in significantly lowering overall fuel costs.

The legislative push for year-round E15 has been ongoing since at least January 2026, when a Republican E15 task force was established to propose relevant legislation. The complexity of negotiations, particularly the intertwining of this policy with the broader farm bill, highlighted the differing priorities and alliances within Congress.
