EU CBAM Carbon Border Tax Liability Estimator

Calculate embedded emissions liability and certificate surrender costs for imports into the European Union under Regulation (EU) 2023/956.

The EU CBAM Formula:
Total Carbon Liability (€) = Import Metric Tons × Embedded Direct Emissions Intensity (tCO₂e / ton) × (EU ETS Carbon Price − Origin Carbon Price Paid). Covered industries: Iron & Steel, Aluminium, Fertilizers, Cement, Hydrogen, Electricity.
Direct Embedded CO₂
1,050 tCO₂
Effective Carbon Gap
€72 / ton
Estimated CBAM Cost
€75,600

The Asian Rebar Rejection of Q1 2026

A trading desk imported 2,000 tons of structural steel into Belgium. The bill of lading was clean, and import duty was paid.

However, the mill in Southeast Asia failed to submit actual mill-level verified smelter emissions reports, forcing European customs brokers to apply the EU's default penal benchmark (2.8 tCO₂e per ton). At €70 per EU ETS allowance, the importer faced an unexpected €392,000 CBAM certificate liability at declaration. Always require certified ISO 14064 emissions documentation before cargo leaves the loading berth.
