Donald Trump repeals 2009 EPA endangerment finding on greenhouse gases

US President Donald Trump has announced the cancellation of the 2009 "endangerment finding," a regulatory document that established greenhouse gases as a threat to public health. This document served as the legal foundation for federal emissions standards, particularly for the automotive industry. The White House described the move as the largest deregulation in American history, estimating it will reduce manufacturing costs by approximately 2,400 USD per vehicle. President Trump characterized the original policy as a burden on the industry that increased consumer prices and linked it to the "Green New Deal." In response, former President Barack Obama stated that the repeal would make Americans less healthy and safe while benefiting fossil fuel companies. Environmental organizations and Democratic governors, including Gavin Newsom of California, have announced intentions to challenge the decision in court. Critics argue the move ignores scientific data and undermines climate change mitigation efforts. The administration maintains that the deregulation will enhance industrial competitiveness and lower energy costs for American consumers.
