EPA Trends on EVs and PHEVs; beginning of a “measurable and meaningful impact” on new vehicle fuel economy and emissions

Green Car Congress

The agency’s reasoning was that since alternative fuel vehicle production has generally been less than 0.1% of total vehicle production until very recently, the impact of excluding alternative fuel vehicles was negligible. In the analysis, EPA uses overall fuel economy in mpg equivalent (mpge) and tailpipe CO 2 emission values.
