A federal appeals court rejected a request to halt an EPA regulation targeting carbon emissions from coal-fired power plants, allowing it to proceed until legal challenges are resolved. The rule, part of President Biden's climate agenda, mandates a 90% reduction in emissions by 2032, impacting coal and new natural gas plants. Industry groups and Republican-led states contested the rule, citing feasibility challenges and grid reliability concerns. The court found no immediate harm as compliance deadlines are set for 2030, with critics arguing the EPA exceeded its authority, while environmental groups applauded the decision for addressing harmful pollution. Despite the ruling, trade groups plan to appeal to the U.S. Supreme Court, claiming the rule undermines electric reliability and is unachievable.
