The U.S. Supreme Court has allowed the Environmental Protection Agency (EPA) to proceed with regulations aimed at reducing greenhouse gas emissions from power plants, marking a significant move in favor of the Biden administration's climate change agenda. This decision, opposed by Republican-led states and industry groups, supports the EPA's authority to enforce stringent emissions limits, including a requirement for coal-fired plants to capture 90% of their carbon emissions by 2032. Justice Clarence Thomas dissented, and Justice Samuel Alito did not participate due to potential conflicts of interest. This ruling aligns with other recent Supreme Court decisions that have temporarily upheld environmental regulations, despite previous rulings that restricted the EPA's authority. Additionally, a federal court in Louisiana has blocked the EPA from enforcing civil rights regulations requiring state environmental regulators to consider disparate impacts on communities of color, signaling a potential retreat in the agency's capacity to protect vulnerable populations. Environmental groups and the Biden administration view these regulations as essential to addressing climate change and its impacts.
