Co-benefits of Global Greenhouse Gas Mitigation for Future Air Quality and Human Health.

ABSTRACT: Actions to reduce greenhouse gas (GHG) emissions often reduce co-emitted air pollutants, bringing co-benefits for air quality and human health. Past studies^1-6 typically evaluated near-term and local co-benefits, neglecting the long-range transport of air pollutants^7-9, long-term demographic changes, and the influence of climate change on air quality^10-12. Here we simulate the co-benefits of global GHG reductions on air quality and human health using a global atmospheric model and consistent future scenarios, via two mechanisms: a) reducing co-emitted air pollutants, and b) slowing climate change and its effect on air quality. We use new relationships between chronic mortality and exposure to fine particulate matter¹³ and ozone¹⁴, glob
