摘　　要：目前,中国的城市生活垃圾产生量已占到全球垃圾产生量的13%,其处理处置已然成为我国建设“无废城市”、实现“碳达峰”“碳中和”目标的关键。对标和梳理了国际通行的4种温室气体排放核算方法,分析了各方法应用于我国城市生活垃圾碳减排核算的适用性和不足。进而基于全生命周期评价方法,在调研分析国内外案例的基础上,总结提出了优化焚烧技术性能、高效利用填埋气、厌氧消化处理厨余垃圾、分类回收利用可回收物、建设生活垃圾处理产业园区等城市生活垃圾碳减排路径,并对每条路径的发展方向进行展望,旨在为城市生活垃圾处理行业在“十四五”期间实现全生命周期绿色、低碳发展提供理论支撑。Nowadays,the production of municipal solid waste(MSW)in China had accounted for 13%of the global production,which would make MSW treatments and disposal the key to achieving“waste-free city”,carbon peaking and carbon neutrality goals.Four main international carbon accounting methods were compared and sorted out,and their practicality and deficiency in carbon emission reduction accounting of MSW in China were analyzed.Proceed to the next step,based on the life cycle method,and on the basis of investigation and analysis of domestic and foreign cases,the carbon emission reduction path of MSW in China,such as optimizing the performance of incineration technology,enhancing utilization of landfill gas,using anaerobic digestion to treat kitchen waste,classification recycling and constructing MSW circular economy industrial park were put forward.The development direction of each path was prospected,aiming to provide theoretical support for the realization of green,low-carbon development in the whole life cycle of the MSW treatment industry during the 14th Five-Year Plan period.
