Estimating the emission of some trace gases in China

The emission of CO2，SO2，NOxfrom burning coal would play important roles in emission of trace gases in China．The estimation for emission of CO2 from burning fossil fuel and from cement production were 577 TgCO2-C and 28 TgCO2-C in 1988．The estimation for the emission of N20 was 0．1 8 Tg N2O—N．As for methane，the total amount of emission was about 33 Tg CH4 in 1988 in China．The emission of SO2，NOxfrom burning coal and oil have been estimated．
