♦ Greenhouse gas: Carbon dioxide ( CO2 )

► Year 1990 —

● Greenhouse gas emission estimate —

Amount: 4,618,692 tonnes of CO2 Emitted (4,618,692 tonnes CO2 Eq.)
Basis: Calculation
Calculation: ([Clinker Production] * [Clinker CO2 Emission Factor]) + (([Cement kiln dust leaving the kiln system] + [Bypass dust leaving the kiln]) * [Kiln dust CO2 emission factor])
