29  Proportion of methane that would have been combusted without upgrade
 (1) For an upgrade project, the proportion of the methane combusted during the reporting period that would have been combusted without the project is worked out using the formula (equation 17):
where:
WB,Ex means the proportion of the methane combusted during the reporting period that would have been combusted without the upgrade project.
WCom,Bef means:
 (a) if equation 19A is calculated on the basis of data only for 2 years in accordance with subsection (7)—the average proportion of the methane from the landfill that is collected and destroyed during the 2 years before the upgrade is started, worked out using equation 19; or
 (b) otherwise—the higher of:
 (i) the average proportion of the methane from the landfill that is collected and destroyed during the 2 years before the upgrade is started, worked out using equation 19; and
 (ii) the average proportion of the methane from the landfill that is collected and destroyed during the 4 years before the upgrade is started, worked out using equation 19A.
WCom,Aft means the average proportion of the methane from the landfill that is collected and destroyed during the 12 months immediately after the upgrade is completed, worked out using equation 18.

Methane collected and destroyed during 12 months after upgrade
 (2) The average proportion of the methane from the landfill that is collected and destroyed during the 12 months immediately after the upgrade is completed is worked out using the formula (equation 18):
where:
WCom,Aft means the average proportion of the methane from the landfill that is collected and destroyed during the 12 months immediately after the upgrade is completed.
 means the factor to convert cubic metres of methane at standard conditions to tonnes of CO2‑e set out in subsection 5.4(1) of the NGER (Measurement) Determination.
MSent,h means the methane sent to the combustion device h during the reporting period, in cubic metres, worked out using equation 8, 9 or 10.
MGen,y means the methane generated by the landfill in year y, in tonnes CO2‑e, worked out using subsection 22(3).
y means the 12 months immediately after the upgrade is completed.

Methane collected and destroyed during 2 years before upgrade
 (3) The average proportion of the methane from the landfill that is collected and destroyed during the 2 years before the upgrade is started is worked out using the formula (equation 19):

where:
WCom,Bef means the average proportion of the methane from the landfill that is collected and destroyed during the 2 years:
 (a) immediately before the upgrade is started; or
 (b) if elected by the project proponent—immediately before the application for declaration of the upgrade project as an eligible offsets project.
