Abstract：Toevaluate thecarbon emission issue during the production processof needle-punched geotextiles，S factory was takenastheresearch subject.Acarbonfootprint modelfortheproductionprocessofneedle-punchedgeotextiles was constructed based on thelifecycle assessment（LCA）method tocalculate thecarbon emissons in stages such as raw material usage，raw material transportation，production manufacturing，and auxiliary equipment operation.Through localsensitivity analysisandglobalsensitivityanalysis，thekeyinfluencing factorsof thecarbon footprint were identified.Combinedwiththe uncertaintyasesmentresultsof the MonteCarlosimulation，anoptimizedpathforenergyconservationandemissionreduction wasultimately proposed.Theresearchresultsshow thatfor everytonof needle-punched geotextiles producedbySfactory，the total carbon footprint of the production process is 4374.61kgCO2 ，with the highest proportion of raw material usage stage， whichisthecorefocusofcarbonreduction.TheMonteCarlosimulationresultsalsoverifythatthecarbonfootprintfals within the 95% confidence interval，confirming thereliabilityof themodel results.Theresearch findings canprovide scientific basis forthecarbonemisionmanagementof needle-punched geotextileproductionenterprisesandfacilitate thegreenandlow-carbon transformation of the industry.
