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, calculated through the same mass balance approach as the estimate for methane content.
 is the Carbon to CO2 mass conversion factor.
Note: Mass balance refers to the Carbon mass balance approach set out in the 2021 API Compendium.
Note 2: If this method is used to methane emissions, it must also be used to estimate carbon dioxide emissions. Likewise, if it is used to estimate carbon dioxide emissions, it must be used to estimate methane emissions.

3.88  Method 3—gas flared from natural gas production
  Method 3 is the same as method 2 under section 3.86, but the emission factor (EFij) must be determined in accordance with method 3 for the consumption of gaseous fuels as specified in Division 2.3.4.

Division 3.3.9B—Natural gas gathering and boosting (emissions that are vented or flared)

3.88A  Application
  This Division applies to fugitive emissions from venting or flaring from natural gas gathering and boosting, including emissions from:
 (a)  the venting of natural gas; and
 (b) the venting of waste gas and vapour streams at facilities that are constituted by natural gas gathering and boosting; and
 (c) the flaring of natural gas, waste gas and waste vapour streams at those facilities.

Subdivision 3.3.9B.1—Natural gas gathering and boosting (emissions that are vented)

3.88B  Available methods
 (1) Subject to section 1.18, method 1 under section 3.88C must be used for estimating fugitive emissions from gas vented during natural gas gathering and boosting.
Note: There is no method 2, 3 or 4 for this Division.
 (2) However, for incidental emissions another method may be used that is consistent with the principles in section 1.13.

3.88C  Method 1—emissions from system upsets, accidents and deliberate releases from process vents—gas gathering and boosting emissions
  Method 1 is, for a process mentioned in column 2 of an item in the following table, as described in the section of the API Compendium mentioned in column 3 for the item.
