The Environmental Protection Agency under the Trump administration plans to announce Monday that it will rescind federal carbon pollution standards for coal- and gas-fired power plants.

EPA Administrator Lee Zeldin is expected to make the announcement on the sidelines of a Group of 20 energy ministers meeting in Houston, according to multiple people familiar with the matter.

The move would eliminate Biden-era 2024 rules that required existing coal plants and certain new natural gas plants to install carbon capture and storage technology to cut emissions sharply. Those mandates have drawn strong opposition from electric cooperatives and utilities facing surging electricity demand from data centers and artificial intelligence growth.

The agency is also set to propose a separate rule that would repeal the finding that greenhouse gas emissions from power plants contribute significantly to dangerous air pollution under the Clean Air Act. This step follows the administration's earlier repeal of the broader 2009 endangerment finding and similar vehicle standards.

Power plants represent the largest industrial source of greenhouse gas emissions in the United States. The Biden rules had projected reductions of about one billion metric tons of carbon dioxide by 2047.

Critics of the original standards argued that carbon capture technology remains unproven at scale and economically unworkable for most facilities. Electric cooperative leaders have called key thresholds in the rules, such as a 40 percent capacity factor trigger for strict requirements, untenable amid rising power needs.

The repeal forms part of the administration's broader effort to roll back Obama- and Biden-era climate policies. Supporters say the changes will remove regulatory barriers, support domestic energy production, and help keep electricity affordable and reliable for American households and businesses.

The final rule is expected to face legal challenges from environmental groups. Earlier proposals to repeal the standards underwent review at the Office of Management and Budget.
