Qi is the quantity of the pure carbonate (i) consumed in the calcining process for the production of cement clinker during the year measured in tonnes and estimated under Division 4.2.5.
Fcal is:
    1.     the amount of the carbonate calcined in the production of cement clinker during the year, expressed as a decimal fraction; or
    2.     if the information mentioned in paragraph (a) is not available—the value 1.
Ackd is the quantity of cement kiln dust lost from the kiln in the production of cement clinker during the year measured in tonnes and estimated under Division 4.2.5.
EFckd is 0.440, which is the carbon dioxide emission factor for calcined cement kiln dust lost from the kiln.
Fckd is:
 (a) the fraction of calcination achieved for cement kiln dust lost from the kiln in the production of cement clinker during the year; or
 (b) if the information mentioned in paragraph (a) is not available—the value 1.
Qtoc is the quantity of total carbon‑bearing non‑fuel raw material consumed in the production of cement clinker during the year measured in tonnes and estimated under Division 4.2.5.
EFtoc is 0.010, which is the emission factor for carbon‑bearing non‑fuel raw material, measured in tonnes of carbon dioxide produced per tonne of carbon.
                                                                                                                                                                                            γ is the factor 1.861 × 10‑3 for converting a quantity of carbon dioxide from cubic metres at standard conditions of pressure and temperature to CO2‑e tonnes.
                                                                                                                                                                                            RCCSCO2 is carbon dioxide captured for permanent storage measured in cubic metres in accordance with Division 1.2.3.
