Abstract:Reviewing the effectiveness of pollution emission reduction in power industry during the 11th five years period, we could see that end-of-pipe measures had difficulty in achieving co-reduction of air pollutants and GHGs in the industry. Based on co-reduction equivalent index (APeq) of air pollutants built in the study, cost-effectiveness analysis and sensitivity analysis of technological and structural adjustment measures in China’s power industry, with specific focus on SO2, NOx and CO2 co-reduction, are made in the study. The results indicate that the end-of-pipe measures could cut down emission of one single air pollutant, with simultaneous increase of emission of the other two pollutants caused by increase of energy consumption. Technological emission reduction measures which mainly count on energy saving, front-end and in-the-process control, and the structure-adjustment measures characterized as new power generation technology substitutions, could achieve co-reduction of SO2, NOx and CO2 with good potential. In additional, based on cost accounting of unit (marginal) pollutant reduction and potential estimation of pollution reduction, reduction road map of SO2, NOx, CO2 and APeq adapting to China’s power industry could be designed, which will help policy-makers to draw up appropriate emission reduction plan.
