Shindell, D., M. Ru, Y. Zhang, K. Seltzer, , , , L. Parsons, A. Challapalli, L. Yang, and A. Glick, 2021: Temporal and spatial distribution of health, labor and crop benefits of climate change mitigation in the US. Proc. Natl. Acad. Sci., 118, no. 46, e2104061118, doi:10.1073/pnas.2104061118.
Societal benefits from climate change mitigation accrue via multiple pathways. We examine the US impacts of emission changes on several factors that are affected by both climate and air quality responses. Nationwide benefits through mid-century stem primarily from air quality improvements, which are realized rapidly, for multiple impacts including human health, labor productivity and crop yields. Benefits from reduced heat exposure become large around 2060, thereafter often dominating. Monetized benefits are in the tens of trillions of dollars for avoided deaths and tens of billions for labor productivity and crop yield increases and reduced hospital expenditures. Total monetized benefits are dominated by health and are much larger than in previous analyses due to improved understanding of the human health impacts of exposure to both heat and air pollution. Benefit-cost ratios are therefore much larger than in prior studies, especially those that neglected clean air benefits, and benefits exceed costs in the first decade rather than only in the latter half of the century when considering climate alone. Furthermore, monetized US benefits largely stem from US emissions reductions. Increased emphasis on the localized, near-term air quality-related impacts would better align policies with societal benefits and, by reducing the mismatch between perception of climate as a risk distant in space and time and the need for rapid action to mitigate long-term climate change, might help increase acceptance of mitigation policies.
