(other than cement clinker production or lime production):
 (a) method 1 under section 4.22;
 (aa) for use of carbonates in clay materials—method 1A under section 4.22A;
 (b) method 3 under section 4.23;
 (ba) for use of carbonates in clay materials—method 3A under section 4.23A;
 (c) method 4 under Part 1.3.
Note: There is no method 2 for this Division.
 (2) However, for incidental emissions another method may be used that is consistent with the principles in section 1.13.

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

        where:
        Eij is the emissions of carbon dioxide (j) released from raw carbonate material (i) consumed in the industrial process during the year measured in CO2‑e tonnes.
        Qi is the quantity of the raw carbonate material (i) consumed in the calcining process for the industrial process during the year measured in tonnes and estimated under Division 4.2.5.
        EFij is the carbon dioxide (j) emission factor for the raw carbonate material (i) measured in tonnes of emissions of carbon dioxide per tonne of carbonate, that is:
         (a) for calcium carbonate—0.396; and
         (b) for magnesium carbonate—0.522; and
         (c) for dolomite—0.453; and
         (d) for any other raw carbonate material—the factor for the raw carbonate material in accordance with section 2.1 of Chapter 2 of Volume 3 of the 2006 IPCC Guidelines.
        Fcal is:
         (a) the fraction of the raw carbonate material consumed in the industrial process during the year; or
         (b) if the information in paragraph (a) is not available—the value 1.
Step 2  Add together the amount of emissions of carbon dioxide for each carbonate consumed in the industrial process during the year.

Note: For the factor Efij in step 1, the emission factor value given for a raw carbonate material is based on a method of calculation that ascribed the following content to the material:
(a) for calcium carbonate—at least 90% calcium carbonate;
(b) for magnesium carbonate—100% magnesium carbonate;
(c) for dolomite—at least 95% dolomite.

4.22A  Method 1A—product other than cement clinker, lime or soda ash for use of carbonates in clay materials
 (1) Method 1A is 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:
Ej is the emissions of carbon dioxide released from the clay material consumed in the industrial process during the reporting year in a State or Territory (j) mentioned in column 2 of an item in the table in subsection (2), measured in
