A coalition of more than 70 biofuel groups and agricultural organizations called for the immediate passage of legislation to allow year-round nationwide sales of the American-made E15 fuel blend, containing 15 percent ethanol.

Year-round E15 would benefit drivers with savings of 10 to 30 cents per gallon and improve markets for America’s farmers, the groups said in a letter to congressional leadership.

“The U.S. Department of Agriculture projects a record 16.8-billion-bushel corn harvest in 2025—up roughly 13 percent from 2024,” the groups wrote. “While this demonstrates the strength and productivity of America’s farmers, it also intensifies pressure on corn prices and farm incomes. Expanding E15 access is one of the most immediate and practical ways to address this imbalance. When fully scaled, year-round, nationwide E15 is poised to create new domestic demand for billions of bushels of corn and sorghum, help stabilize markets, support farmers, and deliver consumer savings at the pump.”

The letter was led by Growth Energy, the American Farm Bureau Federation, the National Corn Growers Association, and the Renewable Fuels Association.

In recent years, the organizations noted, E15 availability during the summer driving season has depended on temporary emergency waivers. While these annual actions provide short-term relief, they are not a sustainable or reliable solution.

Year-to-year uncertainty discourages investment in fuel infrastructure, confuses consumers and undermines confidence among retailers and refiners.

A recent study found that nationwide, year-round E15 sales would add up to $25.8 billion to the U.S. GDP, generate up to $10.3 billion in household income and support more than 128,000 new full-time jobs across the country.

“With a record corn crop filling bins across America, farmers cannot afford another season of uncertainty and negative margins,” the groups wrote. “Markets need consistency and predictability, which requires permanent legislative action by Congress. We respectfully urge you to act this year to pass year-round E15 legislation.”

The groups said year-round E15 legislation would ensure the record corn and sorghum crop finds a stable domestic market and would provide consistent access to lower-priced E15 fuel for consumers nationwide. This legislation would remove an outdated regulatory barrier and deliver economic growth across rural America, while also strengthening America’s energy security and reducing emissions, the groups said.
