The recycling and utilization of construction waste concrete are significant for reducing carbon emissions and conserving resources.Based on the actual situation in Shanghai,this study has proposed a carbon accounting method for the recycling and utilization of construction waste in Shanghai.By evaluating the lifecycle of the recycling process,a carbon emission model that could comprehensively consider stages such as transportation of waste concrete to disposal facilities,production of recycled products,and transportation to the recycled product utilization sites was established.By applying the method in case studies,field research,and data collection,the effectiveness of the proposed method was verified,and targeted improvement suggestions were given.The results show that this carbon accounting method can be used as a scientific assessment and management tool for the recycling and utilization of construction waste concrete in Shanghai.
