specified in Schedule 3, sampling and analysis of fuel type (i) or carbonaceous input material must be carried out to determine its carbon content.
 (3) The sampling and analysis is to be carried out using the methods set out in Divisions 2.2.4, 2.3.4 and 2.4.4 that apply to the combustion of solid, gaseous and liquid fuels.

Division 4.4.3—Aluminium production (carbon dioxide emissions)

4.74  Application
  This Division applies to aluminium production.

Sudivision 4.4.3.1—Aluminium—emissions from consumption of carbon anodes in aluminium production

4.75  Available methods
 (1) Subject to section 1.18, for estimating emissions of carbon dioxide released during a year from the operation of a facility that is constituted by the production of aluminium involving the consumption of carbon anodes, one of the following methods must be used:
 (a) method 1 under section 4.76;
 (b) method 2 under section 4.77;
 (c) method 3 under section 4.78;
 (d) method 4 under Part 1.3.
 (2) However, for incidental emissions another method may be used that is consistent with the principles in section 1.13.

4.76  Method 1—aluminium (carbon anode consumption)
  Method 1 is:

where:
Eij is the emissions of carbon dioxide released from aluminium smelting and production involving the consumption of carbon anodes during the year measured in CO2‑e tonnes.
Ai is the amount of primary aluminium produced in tonnes during the year.
EFij is the carbon dioxide emission factor for carbon anode consumption, measured in CO2‑e tonnes for each tonne of aluminium produced during the year, estimated in accordance with the following formula:

where:
NAC is the amount of carbon consumed from a carbon anode consumed in the production of aluminium during the year, worked out at the rate of 0.413 tonnes of carbon anode consumed for each tonne of aluminium produced.
Sa is the mass of sulphur content in carbon anodes that is consumed in the production of aluminium during the year, expressed as a percentage of the mass of the carbon anodes, and is taken to be 2.
Asha is the mass of ash content in carbon anodes that is consumed in the production of aluminium during the year, expressed as a percentage of the mass of the carbon anodes, and is taken to be 0.4.

4.77  Method 2—aluminium (carbon anode consumption)
 (1) Subject to this section, method 2 is the same as method 1 under section 4.76.
 (2) In applying method 1 under section 4.76, the method for sampling and analysing the fuel type (i) for the factors NAC, Sa and Asha must be determined by sampling and analysing the fuel type for sulphur and ash content, as the case may be, in accordance with:
 (a) for solid fuels—method 2 in Division 2.2.3; and
 (b) for gaseous fuels—method 2 in Division
