The overall level of co2 output makes the cement industry one of the top two manufacturing industry sources of greenhouse gases however, in many countries, the cement industrys contribution is a small fraction of that from fossil fuel combustion by power plants and motor vehicles.
Cement manufacturing processes are associated with emissions of large quantities of greenhouse gases and environmental pollutants. we give below quantitative and qualitative analyses of environmental impact of cement manufacturing. controlling pollution is a mandatory legal and social requirement pertinent to any industry.

A further 40 of cement emissions come from burning fossil fuels to heat kilns to the high temperatures needed for this calcination process. the last 10 of emissions come from fuels needed to mine and transport the raw materials. therefore, cement emissions depend largely on the proportion of clinker used in each tonne of cement.
