4.54  Available methods
 (1) Subject to section 1.18, one of the following methods must be used for estimating emissions released during a year from the operation of a facility that is constituted by the production of a chemical or mineral product:
 (a) method 1 under section 4.55;
 (b) method 2 under section 4.56;
 (c) method 3 under section 4.57;
 (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.

4.55  Method 1—chemical or mineral production, other than carbide production, using a carbon reductant or carbon anode
  Method 1 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 material.
                                                                                                                                                              CCFi is the carbon content factor mentioned in Schedule 3, measured in tonnes of carbon, for each appropriate unit of fuel type (i) or carbonaceous input material consumed during the year from the operation of the activity.
                                                                                                                                                              Qi is the quantity of fuel type (i) or carbonaceous input material delivered for the activity during the year, measured in an appropriate unit and estimated in accordance with criterion A in Divisions 2.2.5, 2.3.6, 2.4.6 and 4.2.5.
Step 2                                                                                                                                                        Work out the carbon content in products (p) leaving the activity during the year, measured in tonnes of carbon, as follows:

p means the sum of the carbon content values obtained for all product types (p).
CCFp is the carbon content factor, measured in tonnes of carbon, for each tonne of product type (p) produced during the year.
