Anthropogenic emissions of SO2 and NOx in Asia: Emission inventories

The anthropogenic emissions of SO2 and NOx for 25 Asian countries east of Afghanistan and Pakistan have been calculated for 1975, 1980, 1985, 1986 and 1987 based on fuel consumption, sulfur content in fuels and emission factors for used fuels in each emission category. The provincial- and regional-based calculations have also been made for China and India. The total SO2 emissions in these parts of Asia have been calculated to be 18.3 and 29.1 Tg in 1975 and 1987, respectively. The calculated total NOx emissions were 9.4 and 15.5 Tg in 1975 and 1987, respectively. The SO2 and NOx emissions in East Asia (China, Japan, South Korea, North Korea and Taiwan) were 23.4 and 10.7 Tg in 1975 and 1987, respectively.
