This report summarizes the technological bases for the U.S. Environmental Protection Agency’s proposed rules limiting greenhouse gas emissions from fossil-fuel-fired electric generating units, issued in May 2023. It then explains in detail how the regulated entities would have numerous technical options to comply, and how deployment of the full range of controls could be facilitated through compliance flexibilities such as trading or averaging of emissions. The report notes that further technical innovation under the final rule should be expected, in line with experience under past Clean Air Act regulations.
