EPA finalizes first carbon limits on existing coal and new gas power plants (2024)
On 25 April 2024, the US Environmental Protection Agency, under Administrator Michael Regan, finalized carbon-pollution standards requiring long-running existing coal plants and new baseload gas plants to cut greenhouse-gas emissions sharply, largely through carbon capture and storage. In the causal graph this event strengthens Decarbonization and climate-mitigation policy, a driver that weakens Global CO2 emissions per capita — an improving welfare path.
Read the full account
On 25 April 2024, the US Environmental Protection Agency, under Administrator Michael Regan, finalized carbon-pollution standards requiring long-running existing coal plants and new baseload gas plants to cut greenhouse-gas emissions sharply, largely through carbon capture and storage. It was the first time the federal government set carbon-dioxide limits on existing coal-fired power plants.

Michael Regan
PersonShared responsibility
verified
As EPA Administrator, Regan led the agency when it finalized the power-sector carbon standards under the Clean Air Act. The contribution is administrative rulemaking in his official capacity.
US Environmental Protection Agency
OrganizationShared responsibility
verified
EPA issued the final Clean Air Act standards for covered existing coal plants and new baseload gas plants. The contribution is the agency's formal rulemaking action.
