Abstract:Basedonacomprehensivelifecycleasessment(LCA)forcontaminatedsoilriskmanagementandcontrol,the boundariesforcarbonemissionaountingweredelineated，andacorespondingcarbonemissioncalculationmethodologywas proposed.Theprimarysourcesofcarbonemisionsidentifiedincludetheproductionandtransportationofbariermaterials， infrastructuredevelopment,andtheexecutionofengineringworks.Utlizingtheproposedcarbonemissoncalculation methodology，anevaluationofthecarbonemisionsassociatedwiththeriskmanagementandcontrolofcontaminatedsoilata non-ferrousmetalprocessingfacityinLiaoningwasconducted.Theresultsindicatethatthetotalcarbonemissonsforthe projectamountto4402.172metrictons，withthecarbonemisionsforisolatingonecubicmeterofcontaminatedsoilbeing 22.8kg.Thestudy'sfindingsrevealthattheproductionofbarrermaterialsisthepredominantsourceofcarbonemissionsinthe risk management and control process,constituting 87.65 % of the total carbon emissions.Following this,the project implementation phasecontributessignificantly，withcarbonemisionsprimarilystemmingfromtheenergyconsumptionofconstructionmachinery, 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.O24 metric tons,which accounts for 3.03% of the total emissions.
