42 Methane combusted or taken to be combusted
(1) The methane combusted or taken to be combusted for a reporting period, in cubic metres, is worked out using the following formula:
| start formula M subscript Com equals summation subscript h M subscript Com comma h end formula | Equation 9 |
| M subscript Com | means the methane combusted or taken to be combusted during the reporting period, in cubic metres. | | h | means, subject to subsection (2):<br> a combustion device; or a biogas upgrading system of a project biomethane facility. | | M subscript Com comma h | means, subject to subsection (2), the methane combusted by combustion device h, or taken to be combusted by biogas upgrading system h, during the reporting period, in cubic metres, worked out using:<br> for a biogas upgrading system, a combustion device that is a boiler, a flare with monitoring and control system, or an internal combustion engine system—equation 10; and for a combustion device that is not a boiler, a flare with monitoring and control system or an internal combustion engine—equation 11. |
(2) If MCom is being worked out for the purposes of calculating MCom, NCT, ED in accordance with equation 7, when determining MCom for the reporting period, h means a combustion device.
Note: This prevents landfill gas sent from the project landfill to biogas upgrading systems from being included when working out methane combusted through emissions destruction activities under equation 7. This in turn prevents double counting of conversion abatement from biomethane, which under Method 2 is already accounted for in equation 3.
Methane combusted by combustion device h or taken to be combusted by biogas upgrading system h—boiler or flare with monitoring and control system or internal combustion engine or biogas upgrading system.
(3) For the purposes of paragraph (a) of the definition of MCom, h in subsection (1), the methane combusted by combustion device h or taken to be combusted by biogas upgrading system h for a reporting period, in cubic metres, is worked out using the following formula:
