【摘要】 垃圾焚烧发电已成为我国的主流垃圾处理方式，碳中和背景下虽然其行业碳排放愈发引起重视，但仍缺少系统性研究。运用中国核证自愿减排量（CCER）方法学，结合案例分析探究了焚烧厂主要碳排放来源，并对全国2016年运行的全部垃圾焚烧厂进行了核算统计，首次认识了全国垃圾焚烧行业的碳排放水平及强度，分析了不同区域、不同规模焚烧厂的碳排放强度情况。结果表明：垃圾自身焚烧产生的CO₂为焚烧厂中最主要的碳排放来源，不同焚烧厂的比例差别较大（34.8%～92.0%）;2016年全国生活垃圾焚烧发电行业的年碳排放量为1 835万t,全国吨焚烧垃圾的平均碳排放强度为0.214 t,受垃圾特性及焚烧工艺等的影响，不同省级行政区间差异显著，在0.122～0.273 t波动；单位兆瓦时上网电量的碳排放强度为0.715 t,与燃煤发电厂相比更低。更多还原

【Abstract】 Waste incineration power generation has become the mainstream waste treatment method in China. Under the background of carbon neutrality, the carbon emission of its industry has attracted more and more attention, but there is still a lack of systematic research. In this paper, China Certified Voluntary Emission Reduction（CCER） methodology is used to explore the main carbon emission sources of incineration plants, and all waste incineration plants operating in China in 2016 are accounted and counted, and the carbon emission level and intensity of waste incineration industry in China are recognized for the first time, and the carbon emission intensity of incineration plants in different regions and sizes is analyzed. The results show that CO₂ generated by waste incineration itself is the most important carbon emission source in incineration plants, but the proportion of different incineration plants is quite different. In 2016,the annual carbon emission of domestic waste incineration power generation industry in China was 18.35 million tons, and the average carbon emission intensity per ton of domestic waste incineration was 0.214 tons. However, due to the influence of waste characteristics and incineration technology, there were significant differences among different provinces, ranging from 0.122 to 0.273 tons. The carbon emission intensity of unit megawatt-hour on-grid electricity is 0.715 tons, which is lower than that of coal-fired power plants.更多还原
