Senior Advisor Susan F. Tierney Contributes to the 2018 Update of the EPA's Endangerment Finding for Greenhouse Gases

December 13, 2018

Analysis Group Senior Advisor Susan F. Tierney is a contributing author to a study, published in Science, updating the scientific evidence supporting the US Environmental Protection Agency's (EPA's) 2009 Endangerment Finding on the impacts of greenhouse gas emissions on public health and welfare. The new study was undertaken to assess changes in the scientific evidence in the nine years since the Endangerment Finding was issued.

The 2009 Endangerment Finding helped establish the legal basis for regulating greenhouse gas (GHG) emissions under the Clean Air Act. It provided support for important aspects of US climate policy, including the emissions standards for vehicles and for fossil fuel-fired electric utility generating units (the Clean Power Plan). In her section of the updated report, Dr. Tierney outlined the increased risk of serious adverse impacts on energy, infrastructure, and settlements, including from reduced water availability and extreme weather events. 

Dr. Tierney also was interviewed about the report’s findings in E&E News’ coverage of the release.
