Abstract

EPA is requesting comment on data sources and analytical approaches on which to base an EPA determination of an updated weighting factor (F-factor) for E85 flexible fuel vehicles for model years 2021 and later. The F-factor for a given vehicle model year is used to weight the greenhouse gas (GHG) emissions of a flexible fuel vehicle operating on E85 with the GHG emissions of the vehicle operating on conventional gasoline, when calculating the compliance value for that model year. The F-factor is also used in the Corporate Average Fuel Economy program for weighting the measured fuel economy of flexible fuel vehicles when operating on E85.
