cement mill emission

Worldwide cement production results in the emission of 2 GtCO 2 2015at a global average CO 2 intensity of 08 tCO 2 tcement some 5 of total anthropogenic CO 2 emissions These emissions are split roughly equally between CO 2 emitted from the calcination process 52 and emissions from the combustion of fuel to fire cement kilns 48
