The Trump administration is expected to finalize a rule that repeals Biden-era carbon emissions limits for existing coal plants and new gas plants. The EPA rule, set to be announced by Administrator Lee Zeldin, would also argue that the agency lacks authority to regulate greenhouse gases from the power sector, which accounts for nearly a quarter of US emissions. The move follows the administration's earlier decision to overturn the 2009 Endangerment Finding. Environmental groups and legal experts are expected to challenge the rule in court, pointing to conflicting legal justifications in the repeal and the broader authority question. The rule would not remove the underlying economic pressure on coal, but it would remove the main federal climate constraint on the power fleet.
