(57) A cement production carbon emission accounting method, comprising the following steps: directly measuring total carbon dioxide emissions by means of an instillment; checking activity level data of each emission source in cement production; determining the emission factor for carbonates in each emission source; calculating total carbon dioxide omissions by means of a carbonate feeding accounting method; and comparing the total carbon dioxide emissions directly measured by the instrument with the total carbon dioxide emissions calculated by the carbonate feeding accounting method, so as to obtain final total carbon dioxide.
