US Revokes Limits on Power Plants' Climate Pollution

The US Environmental Protection Agency (EPA) has revoked limits on greenhouse gas emissions from power plants, reversing a 2021 rule that required a 1.9% annual reduction in emissions from 2023 to 2030. The new rule, announced by the EPA on September 15, 2026, eliminates the regulatory framework for controlling carbon dioxide emissions from power generation, effectively ending the Obama-era Clean Power Plan. The move is expected to lead to increased emissions of CO2, a major contributor to climate change, and is seen as a major setback for environmental groups and a victory for fossil fuel interests.
