Abstract：The carbon emission calculation boundary was determined and the carbon emission calculation method was constructed based on the life cycle analysis of contaminated soil stabilization. Stabilizer production, infrastructure construction, filed application, and disposal of stabilized soil were the main source of carbon emission. The carbon emissions generated from scheme design, aging of the stabilized soil and effectiveness evaluation accounted for a small proportion. The carbon emission was accounted to 421516.31kg for an abandoned Arsenic plant contaminated soil ex-situ stabilization process, and 34.78kg for the stabilization of per ton contaminated soil. The raw material production of stabilizer was the most important carbon emission source of stabilization process, accounting for 86.26% of the total carbon emission, followed by the energy consumption of raw material and stabilizer transportations, accounting for 10.82% of the total carbon emission. Developing low-carbon stabilizer and shortening transportation distance are effective to reduce the carbon emission of contaminated soil stabilization.
