Biofuels' Best Summer Starts Now

The EPA's emergency E15 waiver and record RFS volumes create the strongest demand signal for US biofuels in years

30 Mar 2026

In the annals of American farm policy, few things focus legislative minds quite like a conflict in the Middle East. On March 25th, the Environmental Protection Agency issued an emergency waiver permitting nationwide summer sales of E15 gasoline, a blend containing 15% ethanol, from May 1st. The trigger was familiar: rising oil prices abroad. The beneficiaries are closer to home.

E15 is already sold at more than 3,000 filling stations and works in 96% of vehicles on American roads. Drivers who use it typically save between 25 and 30 cents per gallon compared to standard fuel. Without the waiver, summer volatility rules would have curtailed sales across roughly half the country at precisely the moment motorists feel the pinch. The EPA did not stop there. It simultaneously finalised record-high Renewable Fuel Standard volume obligations for 2026 and 2027, projecting a $31 billion market for corn and soybean oil in biofuel production this year alone. Biodiesel and renewable diesel output, the agency estimates, will need to grow by more than 60% from 2025 levels. Net farm income, in its accounting, could rise by $3 to $4 billion; more than 100,000 jobs could follow.

Industry groups welcomed the package, though their enthusiasm came wrapped in impatience. Growth Energy and the American Coalition for Ethanol both called on Congress to legislate permanent year-round E15 access. The awkward arithmetic: emergency waivers are now entering their fifth consecutive year. As the American Coalition for Ethanol put it, the announcements represent "a historic step forward," but durable market certainty requires a legislative fix that waivers cannot provide.

The broader dynamic is instructive. Geopolitical disruption has converted energy independence from a long-run aspiration into an immediate political argument. That suits corn-state senators well. Whether it suits lawmakers enough to close a regulatory gap that five successive emergencies have papered over is, as ever, another question.
