Policies to mitigate greenhouse gas (GHG) emissions will not only slow climate change but can also have ancillary benefits of improved air quality. Here we examine the co-benefits of both global and regional GHG mitigation for US air quality in 2050 at fine resolution, using dynamical downscaling methods, building on a previous global co-benefits study (West et al., 2013).

2.1 million deaths from the effects of air pollution occur each year across the globe finds this study published in the latest edition of journal Environmental Research Letters by Raquel A Silva & et al.
