- Estimation of Carbon Emission during Sponge City Reconstruction of Residential Community
- 摘要:
- 社区海绵化改造是海绵城市建设在流域-城市-社区层级中最基础的环节，其碳排放的核算方法对于节能减排、实现碳中和具有重要的意义。以海绵城市建设过程为研究对象，针对其碳排放量底数不清、核算方法及减排途径有待深入研究的现状，以联合国政府间气候变化专门委员会（IPCC）指南为主要依据，基于生命周期评价法，构建了适用于居住社区海绵改造过程的碳排放核算方法，并以上海浦东新区潍坊街道社区为例，对海绵改造前后的碳排放量进行了具体核算，分析碳减排途径与效果。结果表明，海绵改造中直接碳排放主要来自于海绵设施降解污染物产生的碳排放；间接碳排放包括材料生产碳排放、运输碳排放和设备电耗能耗碳排放；碳汇则来自于海绵设施运行过程中的绿化固碳、雨水利用、径流削减、雨水净化、建筑节能等过程。全生命周期（30年）内的直接碳排放量(以CO2计)为152.9 t，间接碳排放量为714.5 t，碳汇总量为2 070 t，预期在6.5年有望达到碳中和。绿化固碳是海绵改造过程中主要的碳汇来源，应尽可能充分利用现状绿地，避免大改大建，以期在实现海绵设施控流减污的同时，综合考虑碳排效应。
- Abstract:
- Community sponge reconstruction is the most basic part of sponge city construction at the level of river basin, city and community, and its carbon emission estimation method is of great significance for energy conservation and carbon neutralization. During the sponge city construction process, there are problems of unclear carbon emission base and lack of estimation method and emission reduction way. A carbon emission estimation method suitable for sponge reconstruction of residential communities was established based on the guidelines of the intergovernmental panel on climate change (IPCC) and the life cycle assessment (LCA) method. The carbon emission before and after sponge reconstruction was calculated in Weifang Street Community, Pudong New Area, Shanghai, and the carbon emission reduction effect was analyzed. The direct carbon emission during the sponge reconstruction city was mainly from the degradation process of pollutants in the sponge facilities. The indirect carbon emissions included the material production, transportation and power consumption of the equipments. The carbon sink was from greening carbon sequestration, rainwater utilization, runoff reduction, rainwater purification, building energy conservation and other processes during the operation of sponge facilities. In the whole life cycle (30 years), the direct carbon emission was 152.9 tons, the indirect carbon emission was 714.5 tons, and the total carbon sink was 2 070 tons. It was expected to reach the carbon neutralization in 6.5 years. The greening carbon sequestration was the main source of carbon sink in the process of sponge reconstruction. Therefore, it is necessary to make full use of the current green space as far as possible to avoid large-scale reconstruction, so as to realize the flow control and pollution reduction of the sponge facilities and comprehensively consider the carbon emission effect.
