The US Environmental Protection Agency has finalized a rule that repeals Biden-era limits on carbon dioxide emissions from coal and gas power plants. The agency also proposed a separate rule arguing it lacks authority to regulate greenhouse gases from the power sector, which accounts for about a quarter of US emissions. This follows the earlier reversal of the 2009 Endangerment Finding. Environmental groups have pledged to sue, pointing to legal contradictions in the EPA's reasoning. The move aligns with the administration's broader climate rollback agenda, including withdrawal from the Paris Agreement and weaker vehicle emission standards. The impact on carbon markets and grid decarbonization could be significant, as the power sector is a major source of emissions and a target for clean energy transition.
