Relative contributions to China’s total emissions in 2010 (recalculated from Li et al. 2017)

Emission source	Total contribution	Dominant pollutant	Remarks
Industry	43%	NOx, SO2, PM2.5, CO, NMVOCs	Cement, iron, and steel plants and industrial boilers are major contributors of SO2, NOx, and PM10
Residential sector	35%	PM2.5, BC, OC and NMVOCs	Lack of data, but coal, oil, and gas and biomass for heating are important contributors
Transportation	11%	PM and CO	Tailpipe exhausts and evaporative emissions
Power plants	8%	NOx, SO2, PM2.5	Emission depends on type of coal (bituminous or anthracite) and type of boiler
Agriculture	4%	NH3, SO2, NOx, PM2.5	China largest emitter of atmospheric ammonia from fertilizers
