Progress seen on overall industry emissions, even as oil and gas emissions rise, EPA finds
By Shannon Kelleher
US power plants, the largest stationary sources of greenhouse gases in the nation, continue to show reduced emissions but the good news from that sector comes as oil and gas emissions rise, according to new regulatory data.
Power plant emissions totaled about 1.5 billion metric tons of carbon dioxide last year, down 7% from 2022, the US Environmental Protection Agency (EPA) reported. The agency collects data from over 8,000 industrial facilities for its Greenhouse Gas Reporting Program, accounting for about half of total US emissions.
However, greenhouse gas emissions from petroleum and natural gas plants increased 1.4% in 2023 over 2022, and the 2023 tally was up 16.4% from 2016, the EPA said.
Nine coal-fired power plants were among the top ten greenhouse gas-emitting industrial facilities for 2023, along with a Texas-based ExxonMobil refinery.
The worst emitter – for the ninth year in a row – was the James H Miller power plant outside Birmingham, Alabama.
Altogether, large industrial facilities’ greenhouse gas emissions, the chemicals that are driving human-caused climate change, dropped by 4% last year, the EPA reported.
“The progress is largely driven by the power sector, [which] has seen steadily declining emissions,” Amanda Levin, director of policy analysis at the National Resources Defense Council, said in an email, noting that the change reflects a shift away from coal over time. “The power sector can, and must, continue to decarbonize,” she said.
