Fifteen AGs Urged DOE to Update Fuel Efficiency Metric

California Attorney General Rob Bonta led a coalition of 15 AGs and three cities in urging the Department of Energy (DOE) to update its petroleum equivalency factor, which is used for calculating how electric vehicles contribute towards manufacturers’ average fleetwide fuel economy, given that they do not use fuel. The comments argue that DOE’s current iteration of the metric relies on outdated data, allowing manufacturers to appear to meet standards required by the Corporate Average Fuel Economy (CAFE) program without actually improving their fleetwide fuel economy. The comments support a petition for rulemaking filed by environmental groups at the end of last year.
