EPA to revoke greenhouse gas limits for coal and gas power plants under Trump administration

# What changed The U.S. Environmental Protection Agency published two actions in the Federal Register after Administrator Lee Zeldin signed them. One is a final rule that partially repeals the Biden-era Carbon Pollution Standards issued in 2024. The other is a supplemental notice of proposed rulemaking that considers removing all greenhouse gas limits on fossil-fuel power plants.

# Agency rationale The administration framed the moves as steps to lower electricity prices and protect energy availability amid higher costs tied to the war with Iran. The EPA said energy producers will save at least $310 million in compliance costs and argued the 2024 standards were not achievable by the 2032 target date and would force plant closures. The agency also suggested coal generation could increase, noting a potential tenfold rise in coal power.

Elected Democrats and environmental organizations criticized the actions. They said the rollback reverses climate protections set under Presidents Joe Biden and Barack Obama and will increase air pollution and climate risks. Maryland Sen. Chris Van Hollen and Rhode Island Sen. Sheldon Whitehouse voiced strong opposition, arguing the decision transfers the costs of climate damages onto families and communities.

# Political response Republican lawmakers who opposed the 2024 regulation praised the rollback. West Virginia Sen. Shelley Moore Capito called ending the rule a win for coal and lower electric bills in states reliant on fossil fuels. Critics framed the rollback as favoring the fossil-fuel industry, noting campaign contributions and political backing for the administration.

# Regulatory and legal context

# Practical implications

• Utilities may delay or cancel investments in carbon control equipment if federal limits are lifted.
• States that prioritize climate goals could adopt or preserve their own stricter limits, creating uneven regulation across the country.
• If coal generation increases as the EPA suggests, local air-pollution levels could rise in regions that host coal plants, with potential health consequences.

# What to watch next The supplemental notice opens a public comment period and could face legal challenges. Congressional oversight is likely, with Republicans generally supportive and Democrats pushing back. States, utilities, and environmental groups will be central actors in how the regulatory gap affects emissions, electricity costs, and permitting decisions.
