"US Set to Implement Revised EV Mileage Rating Rule, Boosting Automakers"

The US Energy Department is set to announce final rules that will soften its proposal to slash electric vehicles' mileage ratings to meet fuel economy requirements, a move that is seen as a win for automakers and the United Auto Workers union. The revised rules will gradually reduce the petroleum equivalent EV fuel economy rating through 2030, giving automakers more time to adjust, and are a response to concerns raised by automakers and the UAW. Additionally, the Environmental Protection Agency is expected to unveil revised vehicle greenhouse gas emissions requirements that will ease proposed yearly requirements through 2030, providing a boost for plug-in hybrid vehicles and scaling back certain proposals that the industry had objected to.
