Abstract

NOx emissions change in China for nearly so years past was estimated on the basis of historical energy consumption state and NOx emission factors. Moreover, NOx emission inventories and characteristics in different provinces, economic sectors and fuel types from 1995 to 1998 were discussed in detail. Total NOx emissions had increased rapidly from 4.76Mt in 1980 to 12.0Mt in 1996. Since then, NOx emissions began to decrease somewhat, and compared with the peak value in 1996, the total emissions in 1998 had decreased about 0.82Mt. Constant imbalance distribution existed all over: more than 70 percent of the total NOx came from coal combustion, more than about 90 percent of the total came from industry, electric power and transportation sectors, and the share of transportation raised steadily with 10.4% in 1995 increased rapidly to 13.0% in 1998; NOx emissions in Hebei, Liaoning, Jiangsu, Shandong, Henan and Guangdong exceeded 0.5Mt, while those in Ningxia, Qinghai and Hainan were lower than 0.1Mt.
