CBAM Cost Calculator
The Carbon Border Adjustment Mechanism (CBAM) entered its definitive financial phase on 1 January 2026. EU importers of steel, aluminium, cement, fertilisers, hydrogen, and electricity must now purchase CBAM certificates to cover the embedded carbon emissions of their imports. This calculator estimates your certificate cost using EU default emission factors from Commission Delegated Regulation (EU) 2024/3215. Enter your import quantity and the EU ETS price to get an instant estimate: no registration required.

Frequently asked questions
Who needs to buy CBAM certificates?
EU importers of CBAM goods (steel, aluminium, cement, fertilisers, hydrogen, electricity) are required to register as an Authorised CBAM Declarant and purchase certificates annually. The de minimis exemption applies to individual consignments with an intrinsic value not exceeding €150 (Art. 2, Reg. 2023/956). Check with your customs authority for your specific situation.
How is the CBAM certificate cost calculated?
Cost = embedded emissions (tonnes CO₂e) × EU ETS price (EUR/tCO₂e). Embedded emissions use EU default values from Delegated Regulation (EU) 2024/3215 unless you have verified actual supplier data. If your country of origin has a recognised carbon pricing scheme, that price is deducted from the EU ETS price (Art. 9, Reg. 2023/956).
When do I need to surrender certificates?
The annual CBAM declaration and certificate surrender deadline is 31 May each year, covering imports from the prior calendar year. The first financial-phase deadline is 31 May 2027 (for 2026 imports).
Can I reduce my CBAM cost using actual emission data?
Yes. If your supplier provides verified actual embedded emissions below the EU default factor, you may use those figures instead (Art. 4, Reg. 2023/956). This is typically the most effective way to reduce your CBAM liability. Verification must follow Commission Implementing Regulation (EU) 2024/3214.
What is the CBAM certificate price and how is it set?
CBAM certificate prices are set weekly by the European Commission based on the average EU ETS auction price from the preceding week. They track the EU ETS closely. The calculator uses an indicative ETS price: always verify the current weekly CBAM price on the official EU CBAM Registry before any filing.
Which countries are exempt from CBAM?
Countries whose carbon pricing schemes are fully linked to the EU ETS, or are otherwise listed in Annex III of Regulation 2023/956, are exempt. This currently includes EEA members (Iceland, Liechtenstein, Norway), Switzerland (via linked ETS), and a small number of territories. Imports from these countries carry no CBAM obligation.
