In this study commissioned by Ceres, James Heintz, Heidi Garrett-Peltier, and Ben Zipperer examine the economic impacts of air pollution regulations forthcoming from the Environmental Protection Agency: the Clean Air Transport Rule governing sulfur dioxide and nitrogen oxide emissions, and the National Emissions Standards for Hazardous Air Pollutants for Utility Boilers rule, which will set limits for hazardous air pollutants. Focusing on 36 states, the study assesses the potential employment impacts of the transformation of the nation’s energy generation plants to a cleaner, more efficient fleet, through investments in pollution controls and the retirement of outdated plants.
