The U.S. Supreme Court has allowed the Biden administration to enforce new Environmental Protection Agency (EPA) rules aimed at reducing carbon emissions from coal and gas-fired power plants, rejecting emergency requests from Republican-led states and industry groups for a temporary halt. The rules require existing coal plants and new natural gas plants to cut or capture 90% of their emissions by 2032, potentially reducing carbon emissions by 75% compared to 2005 levels. Justices Brett Kavanaugh and Neil Gorsuch acknowledged that challengers have a strong likelihood of success on the merits but noted that compliance deadlines are not imminent. The court's decision marks a notable victory for the Biden administration amid previous rulings that restricted the EPA's regulatory powers. The case will continue in the D.C. Circuit Court, with future appeals possible depending on its outcome. The ruling underscores the administration's commitment to combat climate change despite significant legal opposition.
