Three coalitions of industry groups are filing multiple lawsuits Thursday against the Environmental Protection Agency over its tailpipe emission standards — joining the mounting legal challenges seeking to overturn the strictest federal climate regulation for passenger cars and trucks. 

The lawsuits are challenging the EPA’s finalized rule requiring stricter emission standards for light- and medium-duty vehicles with model years between 2027-2032. Three separate lawsuits were filed in the U.S. Court of Appeals for the District of Columbia Circuit led by the American Petroleum Institute, the American Fuel and Petrochemical Manufacturers, and a coalition of biofuel producers. The groups are filing on behalf of 30 petitioners, encompassing U.S. energy producers and marketers, consumer groups, agricultural organizations, and auto dealers.
