The Environmental Protection Agency has unveiled its rules to regulate greenhouse gas emissions from new power plants. Some politicians and the coal industry have criticized the rules, saying they amount to a ban on new coal-fired plants.
The plan sets an emissions limit of 1,000 pounds of carbon dioxide per megawatt hour for large natural gas plants, and 1,100 pounds per megawatt hour for coal and smaller natural gas plants.
EPA Administrator Gina McCarthy says climate change caused by greenhouse gases like carbon dioxide poses numerous public health challenges—everything from poor air quality to an increase in the number of disease-spreading mosquitoes and ticks. She said these rules for new power plants are necessary, and won’t have the dire economic consequences industry groups predict
“We have proven time after time that setting fair, Clean Air Act standards to protect public health does not cause the sky to fall,” McCarthy said. “The economy does not crumble.”
Technologies like carbon capture and sequestration will help new coal plants comply with the standard; they’re available, but are still very expensive.
