What is the main reason U.S. biofuel production is falling short of the Trump administration's 2026 Renewable Fuel Standard targets?

Production is lagging because U.S. biodiesel plants operated at just under 77% capacity and renewable diesel facilities at 78% in May — well below the EPA’s assumed 90% capacity utilization — while some output is committed to higher-paying export contracts and thus does not generate RINs toward domestic mandates; additionally, policy uncertainty over the federal 45Z tax credit delayed investment and expansion for months until recent guidance was issued.

What are the potential consequences if U.S. biofuel producers fail to meet the 2026 RIN generation targets?

A sustained shortfall could sharply increase renewable fuel credit (RIN) prices and force the Trump administration to invoke a rarely used waiver provision to lower the mandates — an unusual retreat that would upset farmers and biofuel producers, key political constituencies ahead of midterm elections; industry experts also warn the gap is so large — 1.41 billion RINs behind pace through April — that remaining monthly output would need to exceed the industry’s highest-ever monthly production by more than 20% to catch up.

U.S. biofuel production falls short of record EPA mandates, driving RIN prices to record highs and prompting industry lawsuits over compliance costs. Production gaps risk exhausting credit buffers by 2026 amid policy uncertainty.
