摘要
城市管理涉及环境卫生管理、垃圾收运处置、城市照明管理等业务活动,是城市温室气体排放源之一.成都市城市管理领域 2021 年温室气体排放研究表明,垃圾收运处置是该领域最主要的温室气体排放源,贡献比例为 95.81%,其次是城市照明管理和环境卫生管理,排放贡献比例分别为 1.87%和 1.82%.而未来情景分析显示成都市城市管理领域温室气体排放量随生活垃圾焚烧处置率的上升而快速下降,2025 年达到最低,之后随着生活垃圾清运量的增长会呈现缓慢增加的趋势,2030 年达峰时,垃圾收运处置的排放贡献比例为 94.66%,城市照明管理和市政道桥管廊维护的排放贡献比例将上升至 2.80%和 1.20%,环境卫生管理排放贡献比例将下降至 1.07%.最后,提出了双碳背景下城市管理部门开展碳减排工作的对策建议.
Abstract
Urban management,as one of the sources of urban greenhouse gas emissions,involves environmental sanitation management,solid waste collection,transportation and disposal and urban lighting management,etc.The 2021 greenhouse gas emissions study in the field of urban management in Chengdu indicated that solid waste collection,transportation and disposal was the most important source of greenhouse gas emissions,accounted for more than 95.81%.Followed by urban lighting management and environmental sanitation management,with emission contributions of 1.87%and 1.82%,respectively.Future scenario analysis demonstrated that the greenhouse gas emissions would decline rapidly with the increase of domestic waste incineration disposal rate,reached the lowest level in 2025.Then showed a slow increase trend with the growth of domestic waste collection and transportation scale.The emission contribution of solid waste collection,transportation and disposal was 94.66%when the peak was reached in 2030.At the same time,the emission contribution ratio of urban lighting management and municipal road,bridge and utility tunnel maintenance would rise to 2.80%and 1.20%,respectively.The contribution of environmental sanitation management emissions would fall to 1.07%.Finally,the countermeasures and suggestions for carbon emission reduction by urban management departments were proposed under the background of carbon peaking and carbon neutrality.
