Abstract

Policy-makers seeking to limit the impact of coal electricity-generating units (EGUs, also known as power plants) on air quality and climate justify regulations by quantifying the health burden attributable to exposure from these sources. We defined “coal PM 2.5 ” as fine particulate matter associated with coal EGU sulfur dioxide emissions and estimated annual exposure to coal PM 2.5 from 480 EGUs in the US. We estimated the number of deaths attributable to coal PM 2.5 from 1999 to 2020 using individual-level Medicare death records representing 650 million person-years. Exposure to coal PM 2.5 was associated with 2.1 times greater mortality risk than exposure to PM 2.5 from all sources. A total of 460,000 deaths were attributable to coal PM 2.5 , representing 25% of all PM 2.5 -related Medicare deaths before 2009 and 7% after 2012. Here, we quantify and visualize the contribution of individual EGUs to mortality.
