57 Simplified outline of this Division
The carbon dioxide equivalent net displacement abatement amount for a project for a reporting period is worked out separately for each project biomethane facility in relation to the project. These amounts are then added together to give the total amount for the project for the period.
For each project biomethane facility, the gross abatement amount is calculated as the natural gas combustion emissions displaced by the quantity of biomethane produced from biogas upgrading as part of the project. As biomethane and natural gas are identical from a fuel combustion standpoint, it is assumed that displacement occurs on a one-to-one basis.
The gross abatement amount is multiplied by the proportion of biogas that is eligible biogas, to prevent crediting of biomethane created from ineligible waste sources. The fraction of eligible biogas is worked out for each biogas source facility that supplies biogas during a reporting period. If a biogas source facility supplies a mixture of eligible and non-eligible biogas to a project during a reporting period, the fraction of eligible biogas from the biogas must be worked out in accordance with equation 27.
From this are deducted any emissions generated by the operation of the project biomethane facility or associated with the production of biomethane (for example, fuel and electricity used at a project biomethane facility, or fuel used in transporting biomethane).
