as a decimal fraction; or
 (b) if the information mentioned in paragraph (a) is not available—the value 1.
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.
 (2) For subsection (1), EFij is:

where:
FCaO is the estimated fraction of cement clinker that is calcium oxide derived from carbonate sources and produced from the operation of the facility.
FMgO is the estimated fraction of cement clinker that is magnesium oxide derived from carbonate sources and produced from the operation of the facility.
Note: The molecular weight ratio of carbon dioxide to calcium oxide is 0.785, and the molecular weight ratio of carbon dioxide to magnesium oxide is 1.092.
 (3) The cement clinker must be sampled and analysed in accordance with sections 4.6 and 4.7.

4.6  General requirements for sampling cement clinker
 (1) A sample of cement clinker must be derived from a composite of amounts of the cement clinker produced.
 (2) The samples must be collected on enough occasions to produce a representative sample.
 (3) The samples must also be free of bias so that any estimates are neither over nor under estimates of the true value.
 (4) Bias must be tested in accordance with an appropriate standard.
Note: An appropriate standard is AS 4264.4—1996, Coal and coke – Sampling Part 4: Determination of precision and bias.
 (5) The value obtained from the sample must only be used for the production period for which it was intended to be representative.

4.7  General requirements for analysing cement clinker
 (1) Analysis of a sample of cement clinker, including determining the fraction of the sample that is calcium oxide or magnesium oxide, must be done in accordance with industry practice and must be consistent with the principles in section 1.13.
 (2) The minimum frequency of analysis of samples of cement clinker must be in accordance with the Tier 3 method for cement clinker in section 2.2.1.1 in Chapter 2 of Volume 3 of the 2006 IPCC Guidelines.

4.8  Method 3—cement clinker production
 (1) Method 3 is:
Step 1                                                                                                                                                                                      Measure the amount of emissions of carbon dioxide in CO2‑e tonnes released from each pure carbonate calcined in the production of cement clinker during the year as follows:

where:
Eij is the emissions of carbon dioxide (j) released from the carbonate (i) calcined in the production of cement clinker during the year measured in CO2‑e tonnes.
                                                                                                                                                                                            EFij is the carbon dioxide (j) emission factor for the carbonate (i) measured in tonnes of emissions of carbon dioxide per tonne of pure
