For the Iron & Steel Sector CBAM Solution
Carbonaz fully supports the four main routes of steel production (BF-BOF, EAF, DRI-EAF, SR). CBAM 2026 sectoral benchmark values are defined in the system, the Annex II Scope 2 exemption is applied automatically and the CN code 72xx series is fully supported.
Full Support for Every Production Route
The Four Main Production Methods of the Iron & Steel Sector
Customized calculation engines, dedicated process types and correct emission factors for each route.
BF-BOF
Blast Furnace and Basic Oxygen Furnace. Full calculation including hot metal production, coking coal, limestone flux and BOF electrode consumption. Turkey's most common production route.
EAF
Electric Arc Furnace. CBAM 2026 benchmark-compliant calculation for carbon steel and high-alloy steel production. The Annex II Scope 2 exemption is applied automatically.
DRI-EAF
Direct Reduced Iron combined with EAF. Natural gas or hydrogen reduction, DRI process emissions and electricity consumption. The core route for green steel production.
SR (Smelting Reduction)
Customized calculation methodology for smelting reduction processes. Ready infrastructure for advanced technologies such as HIsmelt and COREX.
Calculation Accuracy
CBAM 2026 Benchmark Data Built In
The European Commission's official benchmark values are defined in the system. You do not need to enter them manually for the free allocation (FAA) calculation.
| Product | Benchmark | Source |
|---|---|---|
| Hot Metal / Pig Iron | 1.370 tCO₂/ton | CBAM 2026 Benchmark |
| EAF Carbon Steel (Scrap) | 0.072 tCO₂/ton | CBAM 2026 Benchmark |
| DRI-EAF | 0.481 tCO₂/ton | CBAM 2026 Benchmark |
| EAF High-Alloy Steel | 0.352 tCO₂/ton | CBAM 2026 Benchmark |

Sector-Specific Capabilities
Built From Scratch for Iron & Steel
The Annex II Scope 2 Exemption Is Applied Correctly
For iron and steel, Scope 2 is calculated but not included in the CBAM certificate calculation. Carbonaz manages this automatically, with no manual intervention required.
Full Support for the CN Code 72xx Series
All iron and steel CN codes from 72011000 to 72163100 are defined in the system. Automatic matching when adding a product.
Multi-Tier Precursor Supply Chain
An unlimited-depth supply chain for iron ore, coking coal and alloying elements. You can collect data even from your supplier's supplier's supplier.
Automatic 80/20 Actual Data Rule Check
The actual supplier data ratio is tracked automatically in every calculation. When it drops below 80%, it warns you of the mark-up penalty in advance.
Automatic Process Type Selection by Production Route
Based on the BF-BOF or EAF choice, the appropriate process types (electrode consumption, limestone flux, DRI reduction) appear 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. Project your costs for the coming years.
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.
Specific Calculation for Liquid Iron and Steel
Separate benchmarks and free allocation calculations for hot metal (pig iron), EAF carbon steel and high-alloy steel.
Native-Language Interface and Support
The interface, documentation and support are available in multiple languages. Your team works in its own language.
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) |
