Based on the analysis of coal consumption in Beijing in 2014, the equivalent energy value method was applied to specifically quantifies the reduced emissions of SO2, NOx and CO2 resulting from the measure of electricity in place of coal in Beijing and specific industry. Meanwhile, the reduction contribution rates of different industrial sectors were analyzed under the same substitute proportion. The results show the implementation of electricity in place of coal indeed reduces emission of SO2, NOx and CO2. The reduced emissions of three gases were 5.61×103t、0.42×103t、0.57×106t when 100t coal was substituted by electrial energy. For SO2, the implementation of electricity in place of coal in resident life plays a leading role and the corresponding contribution rate was 53.11%. However, for NOx and CO2, the industy occupies a leading position with contribute rates of 94.06% and 68.36%. The contribution rate of each industrial sector is associated with the corresponding coal consumption. The implementation of electricity in place of coal in Nonmetal Mineral Products and Real Estate would make prominent contribution to the reduction emission of SO2, NOx and CO2in industry and service industry.
