Decarbonizing US Energy System Would Save 50,000 Lives and $600 Billion a Year: Study

A new study adds to the case for urgent decarbonization of the U.S. energy system, finding that slashing air pollution emissions from energy-related sources would bring near-term public health gains including preventing over 50,000 premature deaths and save $608 billion in associated benefits annually.

"Our work provides a sense of the scale of the air quality health benefits that could accompany deep decarbonization of the U.S. energy system," said Nick Mailloux, lead author of the study and a graduate student at the Center for Sustainability and the Global Environment in University of Wisconsin–Madison’s Nelson Institute for Environmental Studies.

"Shifting to clean energy sources," Mailloux said, "can provide enormous benefit for public health in the near term while mitigating climate change in the longer term."

Published Monday in the journal GeoHealth, the analysis by Mailloux and fellow UW-Madison researchers focuses on emissions of fine particulate matter, referred to as PM2.5, and of sulfur dioxide and nitrogen oxides from the electric power, transportation, building, and industrial sectors.
