transformation through the pyrolysis of coal or the coal briquette process.

2.58  Methods
 (1) One or more of the following methods must be used for estimating emissions during the year from combustion of fuels for energy in the manufacture of solid fuels:
 (a) if a facility is constituted by the manufacture of solid fuel using coke ovens as part of an integrated metalworks—the methods provided in Part 4.4 must be used; and
 (b) in any other case—one of the following methods must be used:
 (i) method 1 under subsection (3);
 (ii) method 2 under subsections (4) to (7);
 (iii) method 3 under subsections (8) to (10);
 (iv) method 4 under Part 1.3.
 (2) These emissions are taken to be emissions from fuel combustion.

Method 1
 (3) 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 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 and 2.4.6.
Step 2                                                                                                                         Work out the carbon content in products (p) leaving the activity during the year, measured in tonnes of carbon, as follows:

where:
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.
Ap is the quantity of product types (p) produced leaving the activity during the year, measured in tonnes.
Step 3                                                                                                                         Work out the carbon content in waste by‑product types (r) leaving the activity, other than as an emission of greenhouse gas, during the year, measured in tonnes of carbon, as follows:

                                                                                                                               where:
