Tradeoffs between air pollution mitigation and meteorological response in India.

ABSTRACT: To curb the staggering health burden attributed to air pollution, the sustainable solution for India would be to reduce emissions in future. Here we project ambient fine particulate matter (PM_2.5) exposure in India for the year 2030 under two contrasting air pollution emission pathways for two different climate scenarios based on Representative Concentration Pathways (RCP4.5 and RCP8.5). All-India average PM_2.5 is expected to increase from 41.4 ± 26.5 μg m^-3 in 2010 to 61.1 ± 40.8 and 58.2 ± 37.5 μg m^-3 in 2030 under RCP8.5 and RCP4.5 scenarios, respectively if India follows the current legislation (baseline) emission pathway. In contrast, ambient PM_2.5 in 2030 would be 40.2 ± 27.5 (for RCP8.5) and 39.2 ± 25.4 (for RCP4.5) μg m^-3<
