US Treasury Issues Partial Guidance on Clean Fuel Subsidies, Leaving Key Decisions Unresolved

Biofuel producers express frustration as the Biden administration's interim guidance excludes climate-smart farming practices and defers critical updates to the incoming Trump administration.

  • The U.S. Treasury released short-term guidance on clean fuel tax credits under the Inflation Reduction Act but withheld final details of the program.
  • The guidance excludes climate-smart agricultural practices, disappointing ethanol producers who hoped to use these to meet emissions criteria for subsidies.
  • A new climate model critical to determining subsidy eligibility is expected next week but will limit credits for ethanol and imported used cooking oil as feedstocks for sustainable aviation fuel (SAF).
  • Biofuel industry leaders criticized the lack of clarity and expressed concerns over delayed investment plans, as major program decisions are deferred to the Trump administration.
  • Biden's administration previously set a target of producing 3 billion gallons of SAF by 2030 to reduce aviation emissions, which account for 2.5% of global greenhouse gases.
