1. System boundaries
3.2 Calcined clay
3.2.1. Special provisions
None
3.2.2. System boundary
For calcined clay, direct emissions monitoring shall encompass:
– all processes directly or indirectly linked to the production processes, such as raw material preparation, mixing, drying, and calcining, and flue gas cleaning;
–bCO2 emissions from the combustion of fuels as well as from raw materials, where relevant.
3.3 Cement clinker
3.3.1 Special provisions
No distinction shall be made between grey and white cement clinker.
3.3.2 System boundary
For cement clinker, direct emissions monitoring take into account:
– calcination of limestone and other carbonates in the raw materials, conventional fossil kiln fuels, alternative fossil-based kiln fuels and raw materials, biomass kiln fuels (such as waste-derived fuels), non-kiln fuels, non-carbonate carbon content in raw materials, or alternative raw materials such as fly ash used in the raw meal in the kiln and raw materials used for flue gas scrubbing;
– the additional provisions of point B.9.2. of Annex II.
3.4 Cement
3.4.1 Special provisions
None.
3.4.2 System boundary
For cement, direct emissions monitoring shall take into account:
– all processes directly or indirectly linked to the production processes, where relevant for drying of materials.
3.5 Aluminous cement
3.5.1 Special provisions
None.
3.5.2 System boundary
For aluminous cement, direct emissions monitoring shall take into account:
– all processes directly or indirectly linked to the production processes where fuel is combusted;
– process emissions from carbonates in raw materials, if applicable, and flue gas cleaning.
