For the Cement Sector CBAM Solution
Carbonaz supports the full scope of grey and white clinker production. Calculation is ready for every process, from limestone calcination to fuel combustion, from alternative fuel use to clinker substitution. CBAM 2026 benchmark values are defined in the system and the CN code 2523 series is fully supported.
Process Types
All Processes of Cement Production
Dedicated calculation for every process, from calcination to fuel combustion, from grinding to alternative fuel use.
Calcination (Clinker Production)
The decomposition of limestone (CaCO₃) into CaO and CO₂ at high temperature. About 60% of the cement sector's emissions come from this process and are of mineral origin.
Fuel Combustion
Fuel combustion in the rotary kiln for clinker production. Conventional fuels (coal, petroleum coke) or alternative fuels (waste-derived) can be used.
Cement Grinding
Grinding clinker with other additives (slag, fly ash, gypsum) into cement. Emissions can be reduced by lowering the clinker ratio.
White Clinker Production
Production of special clinker with low iron oxide content. It requires a higher temperature, so its emission intensity is higher. A separate benchmark applies.
Calculation Accuracy
CBAM 2026 Benchmark Data Built In
The European Commission's official clinker benchmark values are defined in the system. You do not need to enter them manually for the free allocation (FAA) calculation.
| Product | Benchmark | Source |
|---|---|---|
| Grey Clinker | 0.666 tCO₂/ton | CBAM 2026 Benchmark |
| White Clinker | 0.859 tCO₂/ton | CBAM 2026 Benchmark |

Sector-Specific Capabilities
Built From Scratch for Cement
Calcination CO₂ Is Calculated Automatically
CO₂ from limestone calcination (CaCO₃ → CaO + CO₂) is calculated as a direct emission. This is the cement sector's largest emission source.
Separate Benchmark for Grey and White Clinker
Separate CBAM 2026 benchmark values are used for grey clinker (0.666) and white clinker (0.859). Correct calculation is performed for different product mixes.
Alternative Fuel Support
Separate emission factors are defined for alternative fuels such as waste-derived fuel (RDF, SRF), biomass and tyre waste. Calculation is based on fuel mix ratios.
Full Support for the CN Code 2523 Series
CN codes 2523 (cement: portland, aluminous, slag, white, etc.) and 2524 (clinker) are defined in the system.
Clinker Substitution Tracking
The ratio of additives such as slag, fly ash and gypsum is tracked. As the clinker ratio falls, emission intensity decreases and an advantage is gained.
Rotary Kiln Process Data
Rotary kiln operating parameters, temperature and clinker production are entered into the system. Process efficiency can be linked to the carbon footprint.
Multi-Tier Raw Material Supply Chain
Collect data at unlimited depth from your raw material suppliers such as limestone, clay, iron oxide and alumina.
Scope 2 Electricity Consumption
Electricity consumption for cement grinding, preheater and fan motors is tracked. Turkey's grid emission factor (IEA 2025) is applied automatically.
Correct Annual Mark-up Penalty Rate
2026 +10%, 2027 +20%, 2028 and beyond +30% are coded correctly. Year-based simulation projects your future cost.
Full CBAM Factor Transition 2026 → 2034
The 0.025 → 1.000 transition schedule is recorded in the system. Because the cement sector is among the most affected, projection is critically important.
Immutable Audit Trail · 7-Year Retention
Every data entry, every calculation and every report is recorded so it cannot be changed retroactively. Ready for SGS verification.
Native-Language Interface and Support
Your team works in its own language. The interface, terms, documentation and support are available in multiple languages.
CBAM Factor Phase-In Schedule
From 2026 to 2034: Cost Projection
The CBAM factor rises year over year, reaching a full 100% in 2034. Carbonaz supports every transition year and shows your future cost today with the mark-up simulator.
| Year | CBAM Factor | Meaning |
|---|---|---|
| 2026 | 0.025 | 2.5% of the gross cost is paid |
| 2027 | 0.050 | 5% |
| 2028 | 0.100 | 10% |
| 2029 | 0.225 | 22.5% |
| 2030 | 0.485 | 48.5% |
| 2031 | 0.610 | 61% |
| 2032 | 0.735 | 73.5% |
| 2033 | 0.860 | 86% |
| 2034 | 1.000 | 100% (full CBAM) |
