11    Others – light crude production            2.10 × 10‑4

Note:   API Publication 4615 defines light crude as oil with an API gravity of 20 or more, and heavy crude as oil with an API gravity of less than 20.
 (b) if the manufacturer of the component supplies component‑specific emission factors for the component type—those factors.

Subdivision 3.3.3.3—Crude oil production (flared)—fugitive emissions of carbon dioxide, methane and nitrous oxide

3.52  Available methods
 (1) Subject to section 1.18, for estimating emissions released by oil or gas flaring during a year from the operation of a facility that is constituted by crude oil production:
 (a) if estimating emissions of carbon dioxide released—one of the following methods must be used:
 (i) method 1 under section 3.53;
 (ii) method 2 under section 3.54;
 (iii) method 3 under section 3.55; and
 (b) if estimating emissions of methane released—one of the following methods must be used:
 (i) method 1 under section 3.53;
 (ii) method 2A under section 3.54A; and
 (c) if estimating emissions of nitrous oxide released—one of the following methods must be used:
 (i) method 1 under section 3.53;
 (ii) method 2A under section 3.54A.
Note: There is no method 4 under paragraph (a) and no method 2, 3 or 4 under paragraph (b) or (c).
 (2) However, for incidental emissions another method may be used that is consistent with the principles in section 1.13.

3.53  Method 1—crude oil production (flared) emissions
 (1) For subparagraph 3.52(a)(i), method 1 is:

where:
Eij is the emissions of gas type (j) measured in CO2‑e tonnes from a fuel type (i) flared in crude oil production during the year.
Qi is the quantity of fuel type (i) measured in tonnes flared in crude oil production during the year.
Note: This quantity includes all of the fuel type, not just hydrocarbons within the fuel type.
EFij is the emission factor for gas type (j) measured in tonnes of CO2‑e emissions per tonne of the fuel type (i) flared.
 (2) For EFij mentioned in subsection (1), columns 3, 4 and 5 of an item in following table specify the emission factor for each fuel type (i) specified in column 2 of that item.
Item  Fuel type (i)          Emission factor for gas type (j) (tonnes CO2‑e/tonnes of fuel flared)
      CO2                    CH4                                                                    N2O
