Abstract
In this study, we employed the NCAR (National Center for Atmospheric Research) Community Earth System Model CAM5-Chem (Community Atmosphere Model coupled with Chemistry version 5.3) model to quantify the impacts of global solid biofuel stove emissions on ambient surface PM2.5 (particulate matter with aerodynamic diameters equal to or less than 2.5 micrometers) and ozone (O3) air quality and human health. Annual mean surface PM2.5 and O3 concentrations from global solid biofuel stove emissions averaged over 2006-2010 were up to 23.1 μg m-3 and 5.7 ppbv, respectively, with large impacts found over China, India and sub-Saharan Africa for both PM2.5 and O3. The global annual total PM2.5- and O3-induced premature deaths associated with solid biofuel stove sector were 382,000 [95% confidence interval (95CI): 349,000-409,000], with the corresponding years of life lost as 8.10 million years (95CI: 7.38-8.70 million years). Our study highlights co-benefits of air quality and human health via promoting clean household energy programs over low-income and middle-income countries.
