3.87  Method 2—gas flared from natural gas production
  Method 2 is:
where:
EiCO2 is the fugitive emissions of CO2 from fuel type (i) flared in the natural gas production during the year, measured in CO2‑e tonnes.
Qh is the total quantity of hydrocarbons (h) within the fuel type (i) in the natural gas production during the year, measured in tonnes in accordance with Division 2.3.3.
EFhi is the carbon dioxide emission factor for the total hydrocarbons (h) within the fuel type (i) in the natural gas production during the year, measured in CO2‑e tonnes per tonne of fuel type (i) flared, estimated in accordance with Division 2.3.3.
OFi is 0.98, which is the destruction efficiency of fuel type (i) flared.
QCO2 is the quantity of CO2 within the fuel type (i) in the natural gas production and processing during the year, measured in CO2‑e tonnes in accordance with Division 2.3.3.

3.87A  Method 2A—natural gas production (flared methane or nitrous oxide emissions)
  Method 2A is:
where:
EFhij is the emission factor of gas type (j), being methane or nitrous oxide, for the total hydrocarbons (h) within the fuel type (i) in natural gas production during the year, mentioned for the fuel type in the table in subsection 3.86(2) and measured in CO2‑e tonnes per tonne of the fuel type (i) flared.
Eij is the fugitive emissions of gas type (j), being methane or nitrous oxide, from fuel type (i) flared from natural gas production during the year, measured in CO2‑e tonnes.
OFi is 0.98, which is the destruction efficiency of fuel type (i) flared.
Qh is the total quantity of hydrocarbons (h) within the fuel type (i) in natural gas production during the year, measured in tonnes in accordance with Division 2.3.3.

3.87B  Method 2B—Natural gas production mass balance approach (flared methane and carbon dioxide emissions)
  Method 2B is:
 (1) For methane emissions:
Where:
ECH4 is the total methane emissions, in tonnes of CO2-e.
Qmethane is the total quantity of methane within the flared gas (k), in tonnes, calculated through a mass balance.
OFk is 0.98, which is the destruction efficiency of gas k.
GWPmethane is the global warming potential of methane as prescribed in the Regulations.
 (2) For carbon dioxide emissions:
Where:
ECO2 is the total carbon dioxide emissions, in tonnes of CO2-e.
Qh is the total quantity of hydrocarbons (h) within the flared gas (k), in tonnes, calculated through a mass balance.
CFk is the carbon weight fraction within the hydrocarbon component of the flared gas k.
OFk is 0.98, which is the destruction efficiency of gas k.
QCO2 is the quantity of carbon dioxide within the flared gas, in tonnes,
