摘　　要：以苏州市5个主城区为研究对象,采用联合国政府间气候变化专门委员会(intergovernmental panel on climate change,IPCC)发布的国家温室气体清单指南(简称IPCC清单指南),并结合碳排放因子法,对垃圾分类后苏州市生活垃圾处理碳排放情况进行分析.结果表明,苏州市开展垃圾分类后,生活垃圾处理碳排放总量波动幅度较小,年碳排放量155万t左右.其他垃圾焚烧处理碳排放强度最大,可回收物资源化利用表现为负碳排放,处理每吨可回收物减碳369.9 kg,碳减排效应显著.苏州市生活垃圾处理碳排放强度由分类前870.46 kg/t下降至410.17 kg/t,表明持续推进垃圾分类工作、提高厨余(餐厨)垃圾和可回收物的资源化利用率是目前减少生活垃圾处理碳排放的有效途径.To study the situation of carbon emissions of municipal solid waste treatment in Suzhou after waste classification,this paper explores the five main urban areas of Suzhou with the method of carbon emission factor and the National Greenhouse Gas Inventory Guidelines from the Intergovernmental Panel on Climate Change(IPCC).The results show that the total carbon emissions of municipal solid waste treatment fluctuate fractionally,and the annual carbon emissions are around 1.55 million tons.Other waste incineration has the highest carbon emission intensity,while the recycling and utilization of recyclable materials represent negative carbon emissions.The carbon reduction of 369.9 kg per ton of recyclables is significant.Based on a slump from 870.46 kg/t to 410.17 kg/t of the carbon emission intensity of municipal solid waste treatment in Suzhou after waste classification,continuing to promote waste classification and improve the recycling efficiency of kitchen waste and recyclables is currently a prominent approach to the decrease of carbon emissions of municipal solid waste treatment.
