Research on the Contribution of Structure Adjustment on SO2 Emissions Reduction---Case Study Shijingshan District, Beijing

Abstract

Having observed the relationship between structure adjustment with the change of SO2 emissions intensity, the author wants to ascertain the effectiveness of industry and energy structure adjustment on the reduction of SO2 emissions at Shijingshan district in Beijing, where the project of relocation of Shougang group and the “coal to gas” have been taken place at “11th five-year plan” period. Through the use of the long-mean Divasia Index Decomposition method (LMDI), the SO2 emissions intensity was decomposed into the contribution from four components: industry structure effect, industrial energy intensity effect, energy structure effect and emission coefficient effect. It was found that the contribution of industry and energy structure effect into the decrease of SO2 emissions intensity were 21.84% and 38.44%, respectively. The result showed that the relocation of Shougang group and the “coal to gas” engineering had a great influence on reducing SO2 emissions, the contribution of structure adjustment is significant. Furthermore, in basis of the reasonable forecast about energy consumption structure and SO2 emissions at “12th five-year plan” period at Shijingshan district, the predictive result shows that the contribution of industry and energy structure effect into the decrease of SO2 emissions intensity will be 6.52% and 58.24%, respectively. This indicates that the structure adjustment will be still the major contributor on SO2 emissions reduction in the future.
