Clean energy policy can provide substantial health benefits through improved air quality. This study estimates the potential health benefits of eliminating emissions from various sectors in the United States, finding that it could prevent over 50,000 premature deaths annually and provide more than $600 billion in benefits from avoided illness and death. The study also shows that a portion of the health benefits remain in the emitting region.
Clean energy policy can provide substantial health benefits through improved air quality. As ambitious clean energy proposals are increasingly considered and adopted across the United States (US), quantifying the benefits of removal of such large air pollution emissions sources is crucial to understanding potential societal impacts of such policy. In this study, we estimate health benefits resulting from the elimination of emissions of fine particulate matter (PM2.5), sulfur dioxide, and nitrogen oxides from the electric power, transportation, building, and industrial sectors in the contiguous US. We use EPA's CO-Benefits Risk Assessment screening tool to estimate health benefits resulting from the removal of PM2.5-related emissions from these energy-related sectors. We find that nationwide efforts to eliminate energy-related emissions could prevent 53,200 (95% CI: 46,900-59,400) premature deaths each year and provide $608 billion ($537-$678 billion) in benefits from avoided PM2.5-related illness and death. We also find that an average of 69% (range: 32%-95%) of the health benefits from emissions removal remain in the emitting region. Our study provides an indication of the potential scale and distribution of public health benefits that could result from ambitious regional and nationwide clean energy and climate mitigation policy. Plain Language Summary Clean energy policy can greatly improve human health by reducing sources of harmful air pollution. In this study, we estimate the health benefits that could be realized if emissions of fine particulate matter, sulfur dioxide, and nitrogen oxides from electricity generation, transportation, buildings, and industrial sources were eliminated in the United States. We find that removing emissions from these sources could prevent more than 50,000 premature deaths each year nationwide and provide more than $600 billion in benefits from avoided death and illness. Some portion of the benefits from removing emissions in one region of the country will be felt in other regions. Between 32% and 95% of the health benefits from eliminating emissions in a region will remain in that region. Our results provide an indication of how substantial the benefits of ambitious clean energy and climate policy could be and the regions of the country where those benefits may occur.
