ANNEX IITier thresholds for calculation-based methodologies related to installations (Article 12(1))

4.Definition of tiers for the calculation factors for process emissions from carbonate decomposition

4.4.Tiers for the conversion factor using Method B

Tier 1

A conversion factor of 1 shall be used.

Tier 2

The amount of non-carbonate compounds of the relevant metals in the raw materials, including return dust or fly ash or other already calcined materials, shall be reflected by means of conversion factors with a value between 0 and 1 with a value of 1 corresponding to a full conversion of raw material carbonates into oxides. The additional determination of relevant chemical parameters of the process inputs shall be carried out in accordance with Articles 32 to 35.
