States and cities sue to block federal rollback of fuel economy standards
A coalition including Connecticut, Maine, Massachusetts, Rhode Island and Vermont asked a federal appeals court to overturn a National Highway Traffic Safety Administration rule weakening mileage requirements for new cars and light trucks.
A coalition of states, counties and cities filed a lawsuit Friday challenging a federal rule that weakens fuel economy standards for new passenger cars and light trucks, according to Connecticut Attorney General William Tong's office.
The suit, filed in the U.S. Court of Appeals for the First Circuit, targets a final rule from the National Highway Traffic Safety Administration. The coalition argues the rule is arbitrary and capricious and violates the Administrative Procedure Act and the Energy Policy and Conservation Act, the 1975 law that requires the agency to set fuel economy standards at the "maximum feasible" level.
The coalition contends the new standards require less efficiency than the U.S. fleet actually achieved in 2021. It argues the rule improperly forces the agency to ignore the millions of electric vehicles already on the road when modeling what automakers can achieve, which the states say distorts the analysis.
The states also allege the agency relied on flawed analyses of vehicle affordability, sales, fuel savings and safety, and glossed over nearly $220 billion in fuel savings drivers would have seen under the previous standards. They say the rule disregards climate-related damages and will end a fuel economy credit trading program in 2028, which they say will hurt the electric vehicle industry.
Tong said gas prices were nearing $5 a gallon and called it "the worst possible time to make our cars less efficient and more wasteful."
Connecticut is joined by the attorneys general of Maine, Massachusetts, Rhode Island and Vermont, along with California, New York, Illinois and other states, the District of Columbia, and the cities of Chicago, Denver, New York and San Francisco.
