The Carbon Border Adjustment Mechanism (CBAM) is a European Union instrument that puts a carbon price on certain imported goods. It aims to prevent carbon leakage by equalizing the cost of CO2 between European producers (subject to the EU ETS) and importers from third countries. Regulation (EU) 2023/956.

Which products are covered by CBAM?

CBAM covers 5 sectors: cement, iron and steel, aluminium, fertilisers (ammonia, urea, nitric acid, ammonium nitrate), hydrogen and electricity. In total, 568 Combined Nomenclature (CN) codes are covered. This calculator covers all of them.

How is the CBAM fee calculated?

Fee = CBAM certificates x certificate price. Number of certificates = MAX(0, marked-up embedded emissions - free allocation). Emissions are calculated from default values (tCO2eq/t) multiplied by imported quantity, with a sector mark-up (10-30% depending on the year). Free allocation = allocation rate x CBAM benchmark x quantity.

What is the sector mark-up?

To incentivize importers to report actual emissions rather than using default values, a penalizing mark-up is applied: 10% in 2026, 20% in 2027, 30% from 2028 for steel, aluminium, cement and hydrogen. Fertilisers have a reduced mark-up of 1%.

How does the CBAM cost evolve between 2026 and 2035?

The free allocation rate decreases progressively: 97.5% in 2026, 95% in 2027, 90% in 2028, 77.5% in 2029, 51.5% in 2030, 39% in 2031, 26.5% in 2032, 14% in 2033, and 0% from 2034. In 2034, importers will pay 100% of the CBAM fee. The cost will therefore increase significantly each year.

Where does this calculator's data come from?

Default emission values, CBAM benchmarks and free allocation rates come from the MACF fee calculator v25.12.0 published by the French General Directorate for Energy and Climate (DGEC). Data covers 568 CN codes, 134 countries and 1,815 benchmarks by production route.

How can I reduce my CBAM fee?

Three levers: (1) report your actual emissions instead of default values (often 40-60% lower), (2) deduct the carbon price already paid in the country of origin (Article 9 of the Regulation), (3) optimize your sourcing by favoring low carbon-intensity suppliers.

Are CBAM certificates the same as ETS allowances?

No. CBAM certificates are distinct from EU ETS allowances. However, their price is aligned with the average ETS allowance price. The first CBAM certificate price was published on April 7, 2026 by the European Commission.

CBAM Calculator

Estimate the cost of the Carbon Border Adjustment Mechanism for your imports. 568 CN codes, 134 countries of origin, 2026-2035 projections.

The CBAM (Carbon Border Adjustment Mechanism) entered its definitive phase on January 1, 2026. This calculator uses official default values from the DGEC (French General Directorate for Energy and Climate) and CBAM benchmarks to estimate the number of certificates to surrender and the associated fee. Select your products, country of origin and imported quantity for an instant estimate.
