“… 16 Previous studies have quantified future air quality changes and their effects on human health under projected emission scenarios at global and regional scales. 5 , 17 , 18 , 19 Studies quantifying the impacts of 2°C mitigation pathways on air pollution and health conclude that health co-benefits are substantial in terms of decreased exposure levels and premature mortality. In addition to significant health benefits, there are also economic gains and cost savings from improving air quality related to reduced mortality, morbidity, work time loss, 20 , 21 , 22 lower medical costs, and carbon saving.…”
