15  Emissions that would have occurred if project not undertaken
  The emissions that would have resulted from the release of the re‑routed gas quantity in relation to a flare device in a reporting period if the oil or gas fugitives (RTF) project had not been undertaken, in tonnes CO2‑e, are worked out using the formula (equation 2):
where:
EV,i means the emissions that would have resulted from the release of the re‑routed gas quantity in relation to flare device i in the reporting period if the project had not been undertaken, in tonnes CO2‑e.
QR,i means the re‑routed gas quantity in relation to flare device i in the reporting period, in tonnes, worked out in accordance with section 19.
s means the number of component gases present in the re‑routed gas quantity in relation to flare device i, worked out:
 (a) if, under section 34, the project proponent has chosen to use historical sampling data in relation to the reporting period—using that data; or
 (b) otherwise—in accordance with the monitoring requirements.
y means a component gas present in the re‑routed gas quantity in relation to flare device i, identified:
 (a) if, under section 34, the project proponent has chosen to use historical sampling data in relation to the reporting period—using that data; or
 (b) otherwise—as a result of monitoring parameters s and molar fraction in accordance with the monitoring requirements.
GWPy means:
 (a) if component y is covered by an item of the table in regulation 2.02 of the NGER Regulations as in force on the declaration day—the Global Warming Potential specified for component y in the table; or
 (b) otherwise—zero.
moly,i% means the molar fraction of component y in the re‑routed gas quantity in relation to flare device i, in mol%, worked out:
 (a) if, under section 34, the project proponent has chosen to use historical sampling data in relation to the reporting period—using that data; or
 (b) otherwise—in accordance with the monitoring requirements.
mwy means the molecular weight of component y, in kilograms per kilomole, set out in the table in subsection 2.22(3) of the NGER (Measurement) Determination.
V means the volume of 1 kilomole of a gas at standard conditions, which is 23.6444 cubic metres.
dTOTAL,i means the density of the re‑routed gas quantity in relation to flare device i, in kilograms per cubic metre, worked out using equation 7.
