摘要
温室气体排放清单是"摸清家底"的重要基础,是助力低碳发展的重要前提.基于惠阳区活动数据,编制了惠阳区2020年温室气体排放清单.惠阳区2020年温室气体直接排放量为122.4万t CO2e,吸收汇为6.87万t CO2e,间接排放量为439.65万t CO2e.CO2是最主要的温室气体,占排放总量的62.3％,能源活动是CO2最大贡献源,占比94.1％,农业活动既是CH4又是N2O最大排放源,占比分别为92.8％,68.2％,而工业生产过程温室气体排放量为0,清单总体不确定性水平为6.65％.惠阳区制定下一阶段低碳发展策略时,需要更重视深入分析具体部门温室气体排放特征,以进一步降低清单不确定性.
Abstract
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.
