Sector-specific CBAM emission calculation and reporting for clinker, grey cement, white cement and lime products.
In the cement sector, the bulk of embedded emission comes from **calcination (process) CO₂** — the inherent CO₂ released by limestone (CaCO₃) during clinker formation, which cannot be eliminated even with fuel switching. CarbonEmit accounts for calcination, fuel combustion and indirect electricity emissions as separate line items.
EU CBAM identifies clinker factor, alternative fuel ratio (RDF, biomass) and waste heat recovery as critical reportable parameters for Turkish cement exporters. Türkiye is a significant cement exporter to the EU market, so producers with reduced clinker intensity gain a CBAM advantage.
The product codes below fall under the EU Carbon Border Adjustment Mechanism (CBAM) and require embedded emission reporting for exports to the EU.

CarbonEmit provides sector-specific emission factors, automatic CN code mapping and CBAM XML/Excel output ready for direct upload to the EU CBAM Transitional Registry.
Clinker (CN 2523 1000), Portland cement (CN 2523 21-29), aluminous cement (CN 2523 30), white cement, calcined clay (CN 2507 0080), calcined bauxite (CN 2517 1000) and calcium aluminate cements (CN 3816 0010) all fall under CBAM.
Calcination emission is calculated as: clinker output × calcium oxide content of clinker × 0.785 (stoichiometric CO₂ ratio). CarbonEmit automatically extracts these values from your XRF analysis report of clinker.
Yes — biomass-derived fuels are treated as carbon-neutral (zero emission) in CBAM accounting. RDF (refuse-derived fuel) reduces emissions proportional to its biogenic content. CarbonEmit applies the biogenic fraction automatically from your fuel mix analysis reports.
If your clinker factor is 65% instead of 75%, your embedded emission per tonne of cement is roughly 13% lower. CarbonEmit calculates product-level emission intensity by accounting for fly ash, granulated blast furnace slag and pozzolan ratios in your product mix recipe.
