What happened
On September 14, 2026 in Houston, EPA finalized repeal of the 2024 Carbon Pollution Standards for fossil fuel power plants and proposed rescinding all remaining power-sector GHG limits.
On September 14, 2026, the US Environmental Protection Agency finalized the repeal of the Biden-era 2024 Carbon Pollution Standards for fossil fuel-fired power plants, removing the main federal limits on climate pollution from the nation's second-largest source of greenhouse gases.
EPA Administrator Lee Zeldin announced the move at the G20 Energy Abundance Ministerial in Houston, framing it as ending a war on coal and protecting affordable energy. The agency projects the finalized repeal will save $310 billion and has proposed rescinding all remaining greenhouse gas standards for the power sector.
The rollback matters because power plants account for roughly 25 percent of US greenhouse gas emissions, second only to transportation. Federal estimates for the original 2024 rule said it would have prevented up to 1,200 premature deaths and 360,000 asthma attacks per year by 2035.
Health and environmental groups including the Sierra Club and the Environmental Law and Policy Center said they will sue, warning that encouraging new gas plants for AI data centers while stripping pollution limits creates a double hit on public health.
Timeline
How the federal carbon cap on power plants was imposed and then scrapped.
- May 2024 — Biden EPA finalizes Carbon Pollution Standards for power plants.
- September 14, 2026 — EPA finalizes repeal at G20 in Houston.
- Next — Sierra Club and ELPC expected to file legal challenges.
Why this matters
Power plants are the biggest stationary source of US climate pollution. Federal limits were the backstop. Removing them shifts burden to courts and states while health benefits are at risk.
Why it matters for me
Power plants face no federal climate pollution limits while $310B in compliance costs are claimed saved and 1,200 lives a year in projected health gains are at risk.
Daily Life
General Public
Health gains at risk as EPA repeals limits that would have prevented 1,200 premature deaths per year by 2035.
Money
Energy Sector
Power plant owners save an estimated $310B from the finalized repeal, plus $370M more if broader rescission is finalized.
Work
Energy Sector
Fossil fuel and data-center-linked gas projects get a freer path while clean energy and litigation work grows.
What to remember
America's second-biggest climate polluter just lost its federal carbon cap.
EPA scraps power-plant carbon limits at G20 Houston, claims $310B saved — 1,200 lives a year in health gains now at risk.

9 claimsOn September 14, 2026, the US EPA finalized the repeal of most of the Biden-era 2024 Carbon Pollution Standards for fossil fuel-fired power plants.
The EPA also proposed rescinding all remaining greenhouse gas emission standards for the power sector, arguing it lacks Clean Air Act Section 111 authority.
The EPA projects the finalized repeal will save $310 billion, and the additional proposed rescissions would save a further $370 million.
The EPA proposed changes will be open for 45 days of public comment and will face legal challenges from Sierra Club and ELPC.
The power sector accounts for about a quarter of US greenhouse gas emissions, surpassed only by transportation.
Federal estimates found the original 2024 rule would have prevented up to 1,200 premature deaths, 870 hospital visits, and 360,000 asthma attacks a year by 2035.
The EPA announced the rollback at the G20 Energy Abundance Ministerial in Houston on September 14, 2026.
The rollback follows the Trump administration's earlier reversal of the 2009 greenhouse gas endangerment finding for vehicles.
Texas leads the US in power-plant carbon emissions, emitting more than 193 million metric tons of CO2 in 2025.
