The U.S. Environmental Protection Agency finalized a repeal of carbon pollution standards for coal and natural gas power plants, ending emission limits established by the Biden administration in 2024.
The agency also announced a supplemental proposal to eliminate EPA authority to regulate power plant carbon pollution altogether.
Had the standards remained in place, they would have delivered $370 billion in net savings by 2035 and prevented 1,200 premature deaths, 1,900 asthma cases, 48,000 school absence days, and 57,000 lost workdays, according to analyses cited by the agency.
Connecticut exceeded federal health-based ozone standards on 23 days in 2024, 22 days in 2025, and 17 days so far in 2026.
