4.3. Tiers for the emission factor using Method B U.K.
Tier 1
:
The operator shall apply the standard factors listed in Annex VI, section 2, Table 3.
Tier 2
:
The operator shall apply a country specific emission factor in accordance with points (b) or (c) of Article 31(1).
Tier 3
:
The determination of the amount of relevant metal oxides stemming from the decomposition of carbonates in the product shall be carried out 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.
