Abstract： As thebackbone of China’s power supply，coal-fired power plants emit alarge amountof polutants，causing a seriesof environmentaland health problems.Basedontheemision factor methodandnational coal-firedunitinformation， a list of CO 2 ，SO 2 ，nitrogen oxides （NOx）， inhalable particulate matter （ PM10 ），fineparticulatematter （ PM2.5 ），BlackCarbon （BC），Organic Carbon （OC），and Non-Methane Volatile Organic Compounds （NMVOCs）emissions from coal-fired power plants in Chinafrom198O to 2O22 was compiled，andthe evolutioncharacteristicsof theiremissionsandinstalledcapacity wereanalyzed.Theemisionsof various species firstincreasedand thendecreased，from2005to2O11，theemissions of various pollutants reached historical peaks one after another. In 2O22，the emissions of SO 2 ，NO x ，and PM2.5 were reduced by 94.7%， 72.3% ，and 87.9% respectively from their peak levels，but the emissions of CO 2 and NMVOCs still remained high.Thestructureoftheunit continued tobeoptimized，in2O22，the proportionof largecapacityunits with a capacity of over 30O MW reached 46.3% ，emissioning over 74.5% of the pollutant.In order to achieve the“dual carbon” goal，there isanurgentneed toaccelerate theapplication ofdecarbonization technologyand strengthenthe controlof NMVOCs emissions.
