America Just Rolled Back Power Plant Rules. The Fine Print Counts the Dead.

Smokestacks, appendices, and authority: six facets of the U.S. power plant carbon regulation rollback

Houston, September 14. On the sidelines of the G20 energy ministers’ meeting, EPA Administrator Lee Zeldin stepped up to the microphone. Behind him, a screen displayed two lines: Affordable. Reliable. He announced the rollback of the Biden-era greenhouse gas emission standards for coal- and gas-fired power plants. On the same day, the EPA issued a supplemental proposal: the agency never had the authority to regulate power plant carbon emissions.

I. The self-negation of authority

The EPA’s supplemental proposal argues that Section 111 of the Clean Air Act does not authorize it to regulate power plants for the purpose of addressing global climate change. The reason: power plant emissions make a “relatively small and declining contribution” to global greenhouse gas concentrations.

The EPA’s own data: the power sector accounts for 24 percent of U.S. greenhouse gas emissions, second only to transportation. Treat the U.S. power sector as a country, and its emissions rank sixth in the world. Those two facts sit together.

The Biden-era standards required existing coal plants and new gas units to gradually cut carbon dioxide by 90 percent, necessitating carbon capture and storage. The EPA says 90 percent carbon capture is “not yet adequately demonstrated,” and that transport and storage infrastructure cannot be built at scale before the 2032 compliance deadline. The EPA did not mention that its own Regulatory Impact Assessment appendix contained another set of numbers.

II. Death numbers in the appendix

The EPA claims the rollback saves $310 billion. That figure is a cumulative modeled value over decades. It does not mean electricity bills will fall next month.

In the EPA’s Regulatory Impact Assessment technical appendix is another set of numbers: rolling back the carbon emission standards would cause, in 2035 alone, about 120 additional ground-level ozone-related premature deaths and 1,100 fine particulate matter-related premature deaths. By 2047, the total increase in health costs could reach $130 billion. That is more than six times the compliance cost savings the EPA claims.

In 2025 public comments, the Environmental Protection Network said the rollback would lead to increased premature deaths, hospitalizations, and asthma cases, with public health costs of $76 billion to $130 billion. Climate benefit losses were not included. The Biden administration estimated that the original rules avoided about 4,500 premature deaths each year. Wang Ruibin of the China Institute of International Studies said the original standards were expected to avoid more than 1,200 premature deaths by 2035 and reduce hundreds of thousands of asthma attacks.

These numbers did not appear in the main text of the proposal. They were in the footnotes to tables in the appendix. In its press release, the EPA said “any potential public health harm is too uncertain, too speculative, too indirect and complex to attribute specifically to the U.S. power sector.” The tables in the RIA appendix, using the same model, produced specific death counts.

III. The G20 podium and the empty chair at COP30

The EPA made the announcement at the G20 energy ministers’ meeting. The China Institute of International Studies called it a political signal of weakening global climate governance.

In January 2026, the United States withdrew from 66 international organizations, conventions, and treaties, including the United Nations Framework Convention on Climate Change and the IPCC. German Environment Minister Schneider said the United States is “isolated” on climate protection. EU Climate Action Commissioner Hoekstra called it “regrettable” and “unfortunate.”

In November 2025, in Belém, Brazil, COP30. The U.S. federal government delegation was absent. Former U.S. Climate Envoy Stern said participants from almost every position considered the United States’ failure to participate fully as a federal government a clear problem. With the world’s second-largest emitter absent, China is accelerating in clean energy. China pledged to cut economy-wide net greenhouse gas emissions by 7 to 10 percent from peak by 2035, and to reach more than six times its 2020 wind and solar capacity.

IV. $700 million and 17%

In June 2026, Trump invoked the Defense Production Act to allocate about $700 million to coal-fired power plants and coal infrastructure. $425 million to upgrade 13 existing coal plants, $75 million to build a coal export terminal in Oakland, California, nearly $200 million to build new coal-fired plants in Alaska and West Virginia, and restart a shut-down plant in Maryland. This is the first new coal-fired generation capacity in the United States since 2013.

Coal once accounted for more than half of U.S. electricity generation. In 2025, about 17 percent. New gas combined-cycle plants cost less than new coal plants. The levelized cost of electricity from wind and solar has fallen to less than half that of coal. Eben Burnham-Snyder, managing director at Signal Group, said: “It’s like throwing money at horse carriages to ease oil prices.”

EPA data show that between 1999 and 2020, air pollution from coal-fired power plants caused as many as 460,000 premature deaths among Americans. A $700 million investment. At the announcement, Trump stressed that “all 10 of these states voted for me.” Patrick Drupp, Sierra Club climate policy director, said: “The President of the United States is donating taxpayer money to deadly and expensive coal plants, which will make Americans sicker and raise electricity prices.”

V. Courts and states

Environmental and public health organizations will sue. The disputes center on whether the EPA can revoke existing emission findings and on the EPA’s reinterpretation of its regulatory authority under Section 111 of the Clean Air Act.

Hawkins, a legal expert at the Natural Resources Defense Council, said the EPA’s action is legally self-contradictory. The technical repeal claims the EPA has authority to regulate but that Biden did it wrong; the supplemental proposal argues the EPA has no authority to regulate at all.

In February 2026, the EPA revoked the 2009 “endangerment finding” for greenhouse gases. This is the legal foundation of federal climate regulation. After the revocation, a future administration seeking to restore similar rules would need to prove anew that power plant emissions constitute a “significant contribution,” or seek clearer authorization from Congress. Twenty-four states and multiple local governments jointly sued.

VI. Numbers and smokestacks

Projected increase by 2050: 1.2 billion to 5.8 billion metric tons of carbon dioxide from the power sector. EPA projection: an increase of about 123 million metric tons of carbon dioxide over the next decade. EIA: U.S. power-sector emissions rose 4 percent year-on-year in 2025.

Nathaniel Keohane, president of the Center for Climate and Energy Solutions, called it “a huge step backward.” He said the EPA “ignores sound science and economics and abandons its responsibility to protect public health and welfare.” Former Vice President Gore said the United States is “going against the whole world.” Clean energy is the “clear answer” to rising costs and energy security.

When the first pile is driven for the Oakland coal export terminal, the sea breeze blows coal dust toward the community. The smokestack of the restarted plant in West Virginia releases water vapor. In the RIA technical appendix, a line of small print: 2035, an additional 120 ozone-related premature deaths. Beneath the table, footnote numbers continue.
