Montana Attorney General Austin Knudsen, along with 20 other states, initiated a lawsuit on Thursday against the Federal Highway Administration and the U.S. Department of Transportation, challenging a recently finalized emissions rule. The rule mandates that states and major metropolitan areas establish decreasing emissions targets for vehicles on the road. However, the lawsuit, filed in Kentucky, argues that the federal government lacks the authority to impose such a rule.
The lawsuit contends, “Regulatory action cannot be used in this manner. Just because the president believes that reducing on-road CO2 emissions is key to addressing climate change… does not mean the agencies can compel the states to administer a federal administrative regulatory program absent statutory authority
