32  Proportion of methane that would have been combusted without upgrade

        (1) For an upgrade project or a transitioning (upgrade) project, the proportion of the methane combusted or taken to be combusted during a reporting period that would have been combusted without the project is worked out using the formula (equation 20):

       where:

       WB, Ex means the proportion of the methane combusted or taken to be combusted during the reporting period that would have been combusted without the project.

       WCom, Bef means:
           (a) if equation 20 is calculated on the basis of data only for 2 years in accordance with subsection (8)—the average proportion of the methane from the project landfill that is collected and destroyed during the 2 years before the upgrade is started, worked out using equation 21; or
           (b) otherwise—the higher of:
              (i) the average proportion of the methane from the project landfill that is collected and destroyed during the 2 years before the upgrade is started, worked out using equation 22; and
              (ii) the average proportion of the methane from the project landfill that is collected and destroyed during the 4 years before the upgrade is started, worked out using equation 23.

       WCom, Aft means the average proportion of the methane from the project landfill that is collected and destroyed during the 12 months immediately after the upgrade is completed, worked out using equation 18.

       Methane collected and destroyed during 12 months after upgrade

        (2) The average proportion of the methane from the project landfill that is collected and destroyed during the 12 months immediately after the upgrade is completed is worked out using the formula (equation 21):

       where:

       WCom, Aft means the average proportion of the methane from the project landfill that is collected and destroyed during the 12 months immediately after the upgrade is completed.

         means the factor to convert cubic metres of methane at standard conditions to tonnes of CO2‑e set out in subsection 5.4(1) of the NGER (Measurement) Determination.

            Note: In 2021, γ was 6.784 x 10-4 x 28.

       MSent, h means the methane sent to the combustion device or biogas upgrading system h during the reporting period, in cubic metres, worked out using equation 10, 11 or 12.

       MGen, y means the methane generated by the project landfill in year y, in tonnes CO2‑e, worked out using subsection 25(3).

       y means the 12 months immediately after the upgrade is completed.

       Methane collected and destroyed during 2 years before upgrade

        (3) The average proportion of the methane from the project landfill that is collected and destroyed during the 2 years before the upgrade is started is worked out using the formula (equation 22):

       where:

       WCom, Bef means the average proportion of
