EPA repeals power plant carbon limits: insurers face rising climate risk as US policy shifts

The EPA finalized a rule eliminating most of the 2024 carbon pollution standards for power plants, including emissions guidelines for existing coal and carbon capture requirements for new gas plants. The agency also proposed rescinding the remaining rules, citing compliance costs and grid reliability concerns driven by AI data centers. The Biden administration had projected the standards would cut 1.38 billion metric tons of carbon pollution through 2047 and deliver up to $370 billion in climate and health benefits. For insurers, the rollback intensifies long-term underwriting risk. Aon's global head of climate risk advisory noted that higher emissions amplify hazards across property, casualty, agriculture, and other lines. Climate Central's vice president for science warned that the repeal points away from needed steep emissions cuts. Insurers are already pulling back from exposed markets, leaving some homeowners without coverage options. The move comes as the US logged its warmest summer in 132 years. The tension between near-term grid reliability and long-term climate risk will shape insurance pricing and availability for years.
