62 Gross abatement amount for a project biomethane facility
The gross abatement amount for project biomethane facility f for a reporting period (GAdisplacement, f), in tonnes CO2-e, is worked out using the following formula:
| k | means a biogas upgrading system at project biomethane facility f used during the reporting period. | | Q subscript BM comma k | means the total volume of biomethane sent out by biogas upgrading system k during the reporting period, in cubic metres, determined in accordance with the monitoring requirements. | | EC subscript NG | means the energy content factor for natural gas distributed in a pipeline, in gigajoules per cubic metre, set out in Part 2 of Schedule 1 to the NGER (Measurement) Determination. | | EF subscript comma CO2 | means the carbon dioxide (CO2) combustion emissions factor for natural gas distributed in a pipeline, in kilograms CO2-e per gigajoule, set out in Part 2 of Schedule 1 to the NGER (Measurement) Determination.<br>Note: Methane (CH4) and nitrous oxide (N2O) emissions are constant regardless of whether biomethane or natural gas is combusted and hence do not result in displacement abatement. |
