× 10‑3 for converting a quantity of carbon dioxide from cubic metres at standard conditions of pressure and temperature to CO2‑e tonnes.
RCCSCO2 is carbon dioxide captured for permanent storage measured in cubic metres in accordance with Division 1.2.3.

2.22  Calculation of emission factors from combustion of gaseous fuel
 (1) For section 2.21, the emission factor EFiCO2oxec from the combustion of fuel type (i) must be calculated from information on the composition of each component gas type (y) and must first estimate EFi,CO2,ox,kg in accordance with the following formula:
where:
EFi,CO2,ox,kg is the carbon dioxide emission factor for fuel type (i), incorporating the effects of a default oxidation factor expressed as kilograms of carbon dioxide per kilogram of fuel.
moly%, for each component gas type (y), is that gas type's share of 1 mole of fuel type (i), or that gas type's share of the total volume of fuel type (i), expressed as a percentage.
mwy, for each component gas type (y), is the molecular weight of the component gas type (y) measured in kilograms per kilomole.
V is the volume of 1 kilomole of the gas at standard conditions and equal to 23.6444 cubic metres.
dy, total is as set out in subsection (2).
fy for each component gas type (y), is the number of carbon atoms in a molecule of the component gas type (y).
OFg is the oxidation factor 1.0 applicable to gaseous fuels.
 (2) For subsection (1), the factor dy, total is worked out using the following formula:

where:
moly%, for each component gas type (y), is that gas type's share of 1 mole of fuel type (i), or that gas type's share of the total volume of fuel type (i), expressed as a percentage.
mwy, for each component gas type (y), is the molecular weight of the component gas type (y) measured in kilograms per kilomole.
 (3) For subsection (1), the molecular weight and number of carbon atoms in a molecule of each component gas type (y) mentioned in column 2 of an item in the following table is as set out in columns 3 and 4, respectively, for the item:

Item  Component gas y     Molecular Wt (kg/kmole)  Number of carbon atoms in component molecules
