摘　　要：Black carbon(BC)is a crucial air pollutant that contributes to short-lived climate forcing and adverse health impacts.BC emissions have rapidly declined over the past three decades and it is important to uncover the major factors behind this decline.Herein,the temporal trends in BC emissions were compiled from 146 detailed sources from 1960 to 2019.Results revealed that the major emission sources were residential solid fuel usage,coke production and brick production.Furthermore,96.9%of the emission reduction from 3.03 Tg in 1995 to 1.02 Tg in 2019 was attributed to these three sources.It was determined that the transition in residential energy/stove usage,phasing-out of beehive coke ovens and brick kiln upgrading were the most important drivers leading to this reduction and will continue to play a key role in future emission mitigation.In addition,this study identified the need to address emissions from coal used in vegetable greenhouses and the commercial sector,and diesel consumption in on/off-road vehicles.
