Taking the sponge city of Chizhou as an example,based on remote sensing land cover data,field measurements and department statistical data,the process of carbon emission and carbon reduction of vari-ous sponge facilities were clarified.Using carbon emission factor method,the carbon reduction of six sponge fa-cilities was analyzed from three paths:runoff reduction,sewage purification and green spaces and water bodies,a carbon emission accounting system applicable to the operation phase of city-scale sponge facilities was constructed.On this basis,the carbon emission was calculated during individual sponge facility operation phase.The results showed that among the three major paths,1 255 953.30 kg emission reduction were from run-off reduction,785 223.90 kg from sewage purification,and 26 354 920.00 kg from green spaces and water bodies.The reduction of regional net carbon emission was 27 004 472.65 kg,mainly due to carbon sequestration by green spaces and water bodies.
