US Government Proposes Stricter EV Sales Targets and Emission Rules for Automakers.

The US Department of Energy has proposed changes to the way it calculates the energy efficiency of electric vehicles (EVs) for corporate average fuel economy (CAFE) standards. If adopted, the changes will downgrade the fuel-efficiency ratings given to EVs, meaning automakers may have to sell four times more EVs to meet CAFE standards. The proposed changes will not affect the consumer-facing MPGe and kWh/100 miles numbers. The DOE agreed to update its calculations after a petition from the Natural Resources Defense Council and the Sierra Club.
