Recognizing the Clean Air Act’s Potential to Address Climate Change

In the summer of 2015, the U.S. Environmental Protection Agency (EPA) released the final version of its Clean Power Plan, which regulates carbon dioxide emissions from existing power plants under the Clean Air Act by establishing emissions targets unique to each state. The goal: achieve a 32 percent cut from 2005 levels by 2030. Years before the rule--in the midst of the congressional climate debate--researchers at the Nicholas Institute partnered with other Duke University faculty to explore the practical strategies to reduce greenhouse gas emissions using existing authority under the Clean Air Act. Learn how these scholars were among the first to recognize that the U.S. Supreme Court decision in Massachusetts v. EPA would likely require the EPA to take action to regulate such emissions under the 40-year-old rule.
