摘　　要：Black carbon is a by-product of incomplete combustion of carbon containing fuels. It can alter atmos-pheric radiation property and make adverse impacts on human health. The energy consumption in Beijing City depends largely on coal burning. Recently,Beijing City has been performing the municipal energy structure adjustment as a tool for air pollution abatement,aiming at the air quality goal for the Beijing 2008 Olympic Games. Based on Beijing energy use data in 2000,combined with emission fac-tors of major sources of black carbon,the emission of black carbon in Beijing City is estimated to be 7.77 Gg. Coke,raw coal and biomass as non-commercial energy are the main contributors to municipal black carbon emissions. Based on Beijing energy planning in the year 2008,the emission of black carbon in 2008 will be 2.97 Gg if the contribution from biomass is not taken into account. Assuming that the black carbon emission from rural biomass in 2008 is the same as that in 2004,the biomass burning will be the largest emitter of black carbon to Beijing City in 2008.Black carbon is a by-product of incomplete combustion of carbon containing fuels.
