Michigan is using antitrust laws to combat climate-related damages lawsuits against the oil and gas industry, a move that could result in a significant financial boost for states tackling climate change. The state argues that the industry acted as a cartel to sideline renewable energy and electric vehicles. If successful, Michigan could seek an award of triple its damages. However, experts warn that the success of this lawsuit is uncertain as it is difficult and expensive to prove. The Trump administration has been in court to block states from filing such lawsuits, arguing they interfere with the federal government's role in national energy policy. The Supreme Court has agreed to take up the industry's argument that federal law bars such cases.
