21  Net conversion abatement amount

        (1) The carbon dioxide equivalent net abatement amount attributable to the treatment of landfill gas from the project landfill by emissions destruction or landfill gas capture for biomethane for a reporting period, in tonnes CO2‑e, is worked out:
           (a) for a biomethane conversion and displacement project or restarting biomethane conversion and displacement project that only undertakes biogas upgrading of landfill gas from the project landfill—using either Method 1 (set out in subsections (2) to (3)) or Method 2 (set out in subsections (4) to (6)); and
           (b) otherwise—using Method 1 (set out in subsections (2) to (3)).

       Method 1—project landfill-only calculation

        (2) The carbon dioxide equivalent net abatement amount attributable to the treatment of landfill gas from the project landfill by emissions destruction or landfill gas capture for biomethane at the project landfill for a reporting period, Aconversion, in tonnes CO2‑e, is worked out using the formula (equation 2):

       where:

       Aconversion means the carbon dioxide equivalent net abatement amount for the project landfill in the reporting period, in tonnes CO2‑e.

       AP means the project conversion abatement for the project landfill in the reporting period, in tonnes CO2‑e, worked out using equation 3.

       AB means the baseline conversion abatement for the project landfill in the reporting period, in tonnes CO2‑e, worked out using equation 15.

       PELFG-BM means the emissions from landfill gas capture for biomethane activities for the reporting period for the project landfill in the reporting period, in tonnes CO2‑e, worked out using equation 23A.

        (3) If, during a reporting period, the project landfill:
           (a) sends landfill gas to a biogas upgrading system; and
           (b) either:
              (i) the landfill gas is used for a purpose other than biogas upgrading to produce biomethane that can reasonably be expected to be combusted within Australia as a natural gas substitute; or
              (ii) the biomethane produced from biogas upgrading cannot be reasonably expected to be combusted within Australia as a natural gas substitute;

         Aconversion for the project landfill is taken to be zero.

       Method 2—project landfill and project biomethane facility calculation

        (4) The carbon dioxide equivalent net abatement amount attributable to the treatment of landfill gas from the project landfill by emissions destruction or landfill gas capture for biomethane for a reporting period, Aconversion, in tonnes CO2‑e, is worked out using the formula (equation 2A):

         where:

       Aconversion means the carbon dioxide equivalent net abatement amount for the project landfill in the reporting period, in tonnes CO2‑e.

       AP, ED means the project conversion abatement from emissions destruction activities for the project landfill in the reporting period, in tonnes CO2‑e, worked out using equation 4.

            Note: AP, ED excludes the abatement associated with methane sent to biogas upgrading systems during the
