12B Working out net abatement

Subject to section 12A, the total carbon dioxide net abatement amount for a reporting period for a wastewater project, Atot, in tonnes CO2-e, is worked out using the formula (equation 1A):

Aconversion, is the carbon dioxide equivalent net abatement amount attributable to the treatment of eligible wastewater by emissions destruction, or biogas generation for biomethane, at a project treatment facility for the reporting period, in tonnes CO2-e, worked out using equation 1B (section 15).

Adisplacement is the carbon dioxide equivalent net abatement amount attributable to biogas upgrading at project biomethane facilities for the reporting period, in tonnes CO2-e, worked out using equation 21 (section 41C).
