Abstract The carbon emission models of engineering refurbished tire were constructed based on life cycle analysis, and the theoretic calculation model and the calculation method of carbon emission were proposed for four stages of engineering refurbished tire with production, transportation, usage and recycle. The carbon emission evaluation indexes of pure carbon surplus, carbon subduction model and carbon subduction rate of engineering refurbished tire were given, and the carbon emission lists at production, transportation and usage stages of engineering refurbished tire were quantitatively analyzed. The carbon emissionsubduction lists of five recycling stages of second refurbishment, combustion decomposition, mechanical smash, power generation by combustion and low temperature smash were analyzed, and the comparing analysis and evaluation of carbon emissions at different stages were performed. The results show that the carbon emission of engineering refurbished tire is maximal at production stage and is minimal at transporting stage. The carbon emission subduction efficiency of second retreading is the best, while those of combustion decomposition and low temperature smash are the worst.
