Cement CSI

[/business/processes/production/cement/csi]

This category provides data and a calculation methodology for greenhouse gas emissions associated with the production of cement using the clinker-based information. This methodology is based on guidelines provided by the Cement Sustainability Initiative (CSI) and used in the WRI Greenhouse Gas protocol worksheets for cement industry greenhouse gas emissions. The methodology is consistent with guidelines for national greenhouse gas inventories issued by the Intergovernmental Panel on Climate Change (IPCC).

There are no drill-down options for this category; the required profile item values are listed below.

Algorithm

Clinker CO2 emissions = EF * clinker quantity

Bypass dust CO2 emissions = EF * bypass dust quantity

CKD CO2 emissions = (CKD quantity * EF) / (1 + EF) * (calcination CKD/100) / (1 - EF / (1 + EF) * (calcination CKD/100))

CO2 emissions = (carbon content/100) * raw clinker ratio * clinker quantity * (44 / 12)

CarbonKit returns the sum of the above. The CO2 produced is found from the carbon content of materials the CO2 molecular mass : carbon atomic mass ratio, 44/12.
