Environmental Protection Agency (EPA) Administrator Lee Zeldin announced a proposal last week to rescind the 2009 Endangerment Finding, which serves as the legal basis for federal greenhouse gas regulations under the Clean Air Act. The announcement was made at a truck dealership in Indianapolis and was attended by Gov. Mike Braun, Attorney General Todd Rokita, U.S. Rep. Jim Baird (R), U.S. Energy Secretary Chris Wright and representatives from the Indiana Motor Truck Association.
The proposed rule would eliminate federal authority to regulate greenhouse gas emissions from vehicles and engines, including light-, medium- and heavy-duty trucks. It would also remove the foundation for federal electric vehicle mandates. EPA officials estimate the repeal could result in up to $54 billion in annual savings.
Zeldin said the Endangerment Finding had led to sweeping federal mandates that raised costs for consumers and businesses. He argued the Clean Air Act does not authorize EPA to regulate greenhouse gases on the basis of climate change and said the agency was acting to restore regulatory authority to Congress.
Braun said Indiana was an appropriate location for the announcement, pointing to the state’s role in manufacturing and logistics. He emphasized the need for policies that support both economic growth and environmental stewardship. Rokita described the proposal as a return to proper constitutional boundaries and a relief for job creators navigating regulatory uncertainty.
The proposed repeal will be subject to a 45-day public comment period. Legal challenges are expected, with environmental groups and several state officials opposing the move. Critics argue the proposal disregards established climate science and may violate existing court rulings.
The Chamber will continue to track the process, evaluate potential impacts and engage with federal and state officials to promote long-term regulatory stability and economic competitiveness.
