4.23  Method 3—product other than cement clinker, lime or soda ash
 (1) Method 3 is:
Step 1  Measure the amount of emissions of carbon dioxide in CO2‑e tonnes released from each pure carbonate consumed in the industrial process during the year as follows:

        where:
        Eij is the emissions of carbon dioxide (j) from a pure carbonate (i) consumed in the industrial process during the year measured in CO2‑e tonnes.
        EFij is the carbon dioxide (j) emission factor for the pure carbonate (i) in tonnes of emissions of carbon dioxide per tonne of pure carbonate, that is:
         (a) for calcium carbonate—0.440;
         (b) for magnesium carbonate—0.522;
         (c) for dolomite—0.477;
         (d) for any other pure carbonate—the factor for the carbonate in accordance with Chapter 2 of Volume 3 of the 2006 IPCC Guidelines.
        Qi is the quantity of the pure carbonate (i) entering the industrial process during the year measured in tonnes and estimated under Division 4.2.5.
        Fcal is:
         (a) the fraction of the pure carbonate consumed in the industrial process during the year; or
         (b) if the information 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.
Step 2  Add together the amount of emissions of carbon dioxide for each pure carbonate consumed in the industrial process during the year.

 (2) Method 3 requires each carbonate to be sampled and analysed in accordance with sections 4.24 and 4.25.

4.23A  Method 3A—product other than cement clinker, lime or soda ash for use of carbonates in clay materials
  Method 3A is:
Step 1  Measure the amount of emissions of carbon dioxide released from each clay material consumed in the industrial process during the reporting year, measured in CO2‑e tonnes, using the following formula:

        where:
        E is the emissions of carbon dioxide released from the clay material consumed in the industrial process during the reporting year, measured in CO2‑e tonnes.
        Q is the quantity of clay material consumed in the industrial process during the reporting year, measured in tonnes and estimated under Division 4.2.5.
        ICC is the inorganic carbon content factor of the clay material.
        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.
        RCCSCO2is carbon dioxide captured for permanent storage, measured in cubic metres in accordance with Division 1.2.3.
Step 2  Identify the amount of emissions of carbon dioxide for each clay material consumed in the industrial process
