Abstract
To mitigate climate change and achieve clean and efficient development in the power sector， it is imperative to vigorously advance pollution and carbon reduction in coal-fired power plants. By incorporating online monitoring data， this study constructs an atmospheric emission inventory for coal-fired units in Shanxi Province for the year 2020 and evaluates their environmental efficiency and emission reduction potential using the SBM-DDF model. The results indicate that： ① In 2020， the emission concentrations of SO2， NOx， and PM from coal-fired units in Shanxi Province ranged from 1.73-28.22， 3.11-43.57， and 0.78-7.39 mg·m-3， respectively， already meeting ultra-low emission standards. The total emissions of CO2， SO2， NOx， and PM were 27 074.21×104， 2.12×104， 5.34×104， and 0.43×104 tons， respectively. ② The average environmental efficiency of coal-fired units in Shanxi Province was 0.71， with reduction potentials for CO2， SO2， NOx， and PM amounting to 11 190.35×104， 1.26×104， 3.22×104， and 0.25×104 tons， respectively. This indicates synergistic benefits in pollution and carbon reduction， albeit at a relatively low level of synergy. ③ Incorporating the heat supply indicator into the input-output framework reduced the environmental efficiency of coal-fired units， suggesting current inefficiencies in combined heat and power operation. ④ From the perspectives of installed capacity and boiler type， smaller units and pulverized coal boiler units exhibited greater potential for pollutant emission reduction.
