H.F. 2754 used to determine progress toward meeting the 25 percent biofuels goal does not include
diesel fuel sales in the denominator of the official progress measure. Rather this formula is:
Official Biofuels Share = (Pure Ethanol Gallons + Pure Biodiesel Gallons)/ Gasoline Gallons
Using this formula, during 2011 biofuels accounted for 9.7 percent of Iowa retail motor fuel sales.
