Abstract

In order to quantitatively evaluate the synergistic effect of pollutant and carbon reduction in Tianjin during the 13th Five Year Plan period, this study adopts the emission factor method to calculate Tianjin's air pollution equivalent and greenhouse gas emissions during the period. At the same time, the emission reduction elasticity coefficient method is used to evaluate the synergistic effect of pollutant and carbon reduction. The results showed that the main sources of air pollution equivalent and greenhouse gas emissions were industrial sources during the 13th Five Year Plan period in Tianjin. The air pollution equivalent had a high degree of correlation with the sources of greenhouse gases. There would be synergistic effects in reducing pollution and carbon in Tianjin from 2016 to 2017, but there was no synergistic effect in reducing pollution and carbon in Tianjin from 2018 to 2020. During the 13th Five Year Plan period in Tianjin, overall pollution reduction and carbon reduction would not have a synergistic effect. To achieve synergy in reducing pollution and carbon, Tianjin needed to promote a continuous decline in the total amount of greenhouse gases.
