Abstract
Based on a comprehensive life cycle assessment(LCA)for contaminated soil risk management and control,the boundaries for carbon emission accounting were delineated,and a corresponding carbon emission calculation methodology was proposed.The primary sources of carbon emissions identified include the production and transportation of barrier materials,infrastructure development,and the execution of engineering works.Utilizing the proposed carbon emission calculation methodology,an evaluation of the carbon emissions associated with the risk management and control of contaminated soil at a non-ferrous metal processing facility in Liaoning was conducted.The results indicate that the total carbon emissions for the project amount to 4 402.172 metric tons,with the carbon emissions for isolating one cubic meter of contaminated soil being 22.8 kg.The study's findings reveal that the production of barrier materials is the predominant source of carbon emissions in the risk management and control process,constituting 87.65%of the total carbon emissions.Following this,the project implementation phase contributes significantly,with carbon emissions primarily stemming from the energy consumption of construction machinery,amounting to 410.428 metric tons and accounting for 9.32%of the total emissions.Conversely,the infrastructure development phase generates the least carbon emissions,totaling 119.024 metric tons,which accounts for 3.03%of the total emissions.关键词
