Division 4.3 Tiers for the emission factor using Method B:
United Kingdom
Tier 1: The operator shall apply one of the following:
- (a)
the standard factors listed in Annex VI section 2 Table 3.
- (b)
other constant values in accordance with point (e) of Article 31(1), where no applicable value is contained in Annex VI.
Tier 2: The operator shall apply a country specific emission factor in accordance with point (b) or (c) of Article 31(1), or values in accordance with point (d) of Article 31(1).
Tier 3: The operator shall determine the emission factor in accordance with Articles 32 to 35. Stoichiometric ratios referred to in Annex VI section 2 Table 3 shall be used to convert composition data into emission factors assuming that all of the relevant metal oxides have been derived from respective carbonates. For this purpose the operator shall take into account at least CaO and MgO, and shall provide evidence to the competent authority as to which further metal oxides relate to carbonates in the raw materials.
