Cement & Clinker CBAM Carbon Tax Calculator (CN 2523)
Calcination rotary kiln direct factor and clinker ratio calculations.
Quick Technical Summary: Calcination rotary kiln direct factor and clinker ratio calculations. Implementation conforms to Regulation (EU) 2023/956 & 2023/1773.
Specification & Structural Breakdown
Cement production releases significant direct CO2 during limestone calcination in rotary kilns. Clinker (CN 2523 10 00) carries a standard benchmark factor of 0.82 tCO2e/t. Finished Portland cement mixes clinker with gypsum and supplementary cementitious materials.
| CN Code | Product Description | Sector | Direct Factor (tCO2e/t) |
|---|---|---|---|
| 25231000 | Cement clinkers | cement | 0.82 |
| 25232900 | Grey Portland cement | cement | 0.69 |
