Cement — what makes this sector technically different.

Two thirds of the emissions come from a chemical reaction, not from fuel — which is why a cement inventory built from fuel invoices alone is always wrong.

Hardest data points

Where inventories in this sector fail.

  • Process CO₂ from calcination separated from combustion CO₂ — a single figure covering both cannot be verified against either method
  • Carbonate content of the raw meal, and whether the input-based or the output-based method was chosen before the period rather than after the number was known
  • Cement kiln dust and bypass dust leaving the system, and the partial calcination degree applied to it
  • Clinker factor evidenced per cement type and per product, not one plant-level average applied to everything sold
  • Alternative fuel composition, the biomass fraction claimed, and the sampling frequency behind that claim
  • The emission factor for clinker, against the 0.525 t CO₂ per tonne minimum, and the laboratory basis for any installation-specific value
  • Electricity consumption, which counts for cement under CBAM even though it does not for steel or aluminium
  • Where clinker is purchased rather than produced, the precursor data and whether it came from a verification report at all
What is examined

The evidence we will ask for.

  • The monitoring plan, with system boundaries and the division into production processes
  • Raw meal and clinker analyses across the period, with the laboratory method and frequency
  • The clinker-to-cement ratio per product, derived by analysis or material balance and not asserted
  • Fuel receipts reconciled to consumption, with biomass fraction determinations for alternative fuels
  • Kiln dust quantities leaving the system and the calcination degree assumed
  • Electricity meter data at the level the boundary requires
CBAM

What CBAM says about this sector specifically.

Cement is a CBAM good and carries both direct and indirect emissions — it is not in the Annex II list of goods for which only direct emissions count. The functional unit is tonnes of clinker contained in the good. Clinker is a precursor to cement, so the clinker-to-cement ratio carries the precursor emissions forward.

Scope note: CBAM verification accreditation has not been granted. Nothing here is offered as accredited CBAM verification before formal grant.

The normative frame

The standards the work runs under.

ISO 14064-1:2018 · ISO 14064-3:2019 · ISO 14067:2018 for product claims. For CBAM: Regulation (EU) 2023/956 and Implementing Regulation (EU) 2025/2547 (methods for calculating embedded emissions).

Scope position: Confirm the specific activity against Accreditation Schedule 1225009B at pre-engagement.
