Iowa Biofuels Access Bill


In 2022, Iowa Governor Kim Reynolds introduced a bill to improve access to higher blends of biofuels, like biodiesel. It passed the House of Representatives with strong bipartisan support.

The key biodiesel provisions of the Governor’s 2022 Biofuel Access Bill are:

  1. Extending a credit for fuel retailers (filling stations and convenience stores) for 11% biodiesel (B11) at 5 cents per gallon until 2027. Also introducing new credits of 7 cpg for B20 and 10 cpg for B30.
  2. Increasing a Biodiesel Production Tax Credit from 2 to 4 cents per gallon and extending the sunset through 2027.

  1. Updating the Biodiesel Fuel Tax Differential to be based on B20 blends beginning in 2026, and expiring in 2030. This would help close any price gap for consumers who want to use biodiesel.
  2. Increasing and updating the Renewable Fuel Infrastructure Program to promote higher blends by requiring retailers to sell B11 and higher blends from April 1 through October 31 if they access infrastructure funds after the effective date.


"The nation is undergoing an energy transformation, mostly driven by other states as well as corporations, and Iowa’s answer to the low-carbon call is biodiesel. If we want Iowa to participate and capture the economic benefits, we need to prioritize smart policy like this. The time to act is now."

“We see a seismic shift in the nation’s energy supply already in motion, and the approach to encourage additional production and use of biofuels to reduce carbon while improving the economy is tried and true. As the nation’s top biodiesel producer, Iowa should stay in the forefront of these forward-thinking changes.”
