by the production of aluminium:
 (b) method 2 under section 4.86;
 (c) method 3 under section 4.87.
Note: There is no method 1 or 4 for this provision.
 (2) However, for incidental emissions another method may be used that is consistent with the principles in section 1.13.

4.86  Method 2—aluminium (tetrafluoromethane)
  Method 2 is the Tier 2 method for estimating perfluorocarbon emissions as set out in the Perfluorocarbon protocol.

4.87  Method 3—aluminium (tetrafluoromethane)
  Method 3 is the Tier 3 method for estimating facility‑specific perfluorocarbon emissions as set out in the Perfluorocarbon protocol.

Subdivision 4.4.4.2—Aluminium—emissions of hexafluoroethane in aluminium production

4.88  Available methods
 (1) Subject to section 1.18, one of the following methods must be used for estimating emissions of hexafluoroethane released during a year from the operation of a facility that is constituted by the production of aluminium:
 (b) method 2 under section 4.90;
 (c) method 3 under section 4.91.
Note: There is no method 1 or 4 for this provision.
 (2) However, for incidental emissions another method may be used that is consistent with the principles in section 1.13.

4.90  Method 2—aluminium production (hexafluoroethane)
  Method 2 is the Tier 2 method for estimating facility‑specific perfluorocarbon emissions as set out in the Perfluorocarbon protocol.

4.91  Method 3—aluminium production (hexafluoroethane)
  Method 3 is the Tier 3 method for estimating facility‑specific perfluorocarbon emissions as set out in the Perfluorocarbon protocol.

Division 4.4.5—Other metals production

4.92  Application
 (1) This Division applies to emissions of carbon dioxide from any of the following:
 (a) the consumption of a fossil fuel reductant;
 (b) the oxidation of a fossil fuel electrode.
 (2) This Division does not apply to the production of any of the following:
 (a) aluminium;
 (b) ferroalloys;
 (c) iron;
 (d) steel;
 (e) any other metal produced using an integrated metalworks.

4.93  Available methods
 (1) Subject to section 1.18, one of the following methods must be used for estimating emissions of carbon dioxide from the use of carbon reductants during a year from the operation of a facility that is constituted by the production of metals to which this Division applies:
 (a) method 1 under section 4.94;
 (b) method 2 under section 4.95;
 (c) method 3 under section 4.96;
 (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.

4.94  Method 1—other metals
  Method 1, based on a carbon mass balance approach, is:
Step 1                                                                                                                                                                                                                           Work out the carbon content in fuel types (i) or carbonaceous input material delivered for the activity during the year, measured in tonnes of carbon, as follows:

where:
i means the sum of the carbon content values obtained for all fuel types (i) or carbonaceous input
