21  Net conversion abatement amount

       (1)  The carbon dioxide equivalent net abatement amount attributable to the treatment of organic effluent by emissions destruction, emissions avoidance, or biogas generation for biomethane, for a reporting period, Aconversion (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 biogas from project treatment facilities—using either Method 1 (set out in subsections (2) to (4)) or Method 2 (set out in subsections (5) to (8)); and
           (b) otherwise—using Method 1 (set out in subsections (2) to (4)).

       Method 1—project treatment facility calculation

       (2)The carbon dioxide equivalent net abatement amount attributable to the treatment of organic effluent by emissions destruction, emissions avoidance, or biogas generation for biomethane, at project treatment facilities for a reporting period, Aconversion (in tonnes CO2‑e), is worked out using the formula:

  Equation 1

       where:

       h is a project treatment facility.

       Aconversion, h is:
           (a) if the project treatment facility net abatement amount for project treatment facility h, calculated using equation 2 (section 22), is greater than or equal to zero—that amount; and
           (b) if that amount is less than zero—zero.

       (3)  However, if a project treatment facility does not comply in all material respects with the requirements of section 16 during the reporting period Aconversion, h for the project treatment facility is taken to be zero.

       (4)  If, during the reporting period, a project treatment facility:
           (a) sends biogas to a biogas upgrading system; and
           (b) either:
                (i) the biogas 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 reasonably be expected to be combusted within Australia as a natural gas substitute;

       Aconversion, h for the project treatment facility is taken to be zero

       Method 2—project treatment facility and project biomethane facility calculation

       (5)  The carbon dioxide equivalent net abatement amount attributable to the treatment of organic effluent by emissions destruction, emissions avoidance, or biogas generation for biomethane, for a reporting period, Aconversion (in tonnes CO2‑e), is worked out using the formula:
  Equation 1B

       where:

       γ is the factor, used in Part 5.3 of the NGER (Measurement) Determination, that converts cubic metres of methane to tonnes CO2‑e at standard conditions.

            Note: In 2022, γ was 6.784 x 10-4 x 28.

       h is a project treatment facility.

       Aconversion, h is:
           (a) if the project treatment facility net abatement amount for project treatment facility h calculated using equation 2 (section 22) is greater than or equal to zero—that amount; and
           (b) if that amount is less than zero—zero.

       f is
