The US Environmental Protection Agency is finalizing a rule to rescind carbon pollution standards for fossil fuel-fired power plants. The move drops Biden-era requirements that forced plants to install carbon capture and storage systems, and it may also revoke the power-sector endangerment finding under the Clean Air Act. The announcement is expected around September 14, 2026, coinciding with a G20 energy ministers meeting in Houston. This follows earlier EPA actions to roll back vehicle climate rules and challenge the 2009 endangerment finding. Without federal limits, power plant emissions will not face the same binding constraints. The repeal could affect carbon market dynamics and investment signals for CCS and renewables, though state-level policies and market pressures may still drive some decarbonization.
