Greenhouse gas emission inventory is the important basis for finding out the background and the important prerequisite for low-carbon development.Based on the activity data of Huiyang District,a greenhouse gas emission inventory was developed.The results showed that the direct CO2e emission in Huiyang was 1.224 million tons;the CO2e absorption was 68.7 kilo tons;indirect CO2e emission was 4.396 5 million tons.The CO2 was the main greenhouse gas,accounting for 62.3％of the total emissions.Energy was the largest emission source,contributing 94.1％to the total CO2 emissions.Agriculture were both the largest contributors of CH4 and N2O,accounting for 92.8％and 68.2％respectively.The greenhouse gas emission from industrial processes was zero.The uncertainty of the emission inventory was 6.65％.To formulate a low-carbon policy for the next stage,Huiyang needs to pay more attention to clarify the greenhouse gas emissions characteristics from the specific sectors to reduce the uncertainty of the emission inventory.
