A coalition of states and cities has filed lawsuits against federal agencies, challenging new vehicle fuel economy standards that they argue undermine environmental protections and public health. The legal action claims the rules weaken long-standing emissions regulations, potentially allowing automakers to produce less efficient vehicles. Critics say the changes could increase greenhouse gas emissions and harm efforts to combat climate change. The lawsuits highlight a growing divide between state governments and the federal government over environmental policy.
