- 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.
