EU CBAM Liability Calculator

Project the number of CBAM certificates you must surrender and the resulting liability by combining embedded emissions, any transitional free allocation, and eligible foreign carbon price credits.

Total metric tons of goods within CBAM scope imported during the reporting period.
Verified direct + indirect emissions per metric ton of product exported to the EU.
Average weekly EU ETS price used to value CBAM certificates.
Optional. Defaults to 0%. Apply when partial EU free allowances remain for the product line.
Optional. Defaults to €0. Enter the effective carbon price already paid in the country of production.

Examples

  • 850 t steel coils, 1.85 tCO2e/t, €82 reference price, 2.5% free allocation, €18 foreign carbon price ⇒ Gross 1,572.50 tCO₂e, payable 1,533.19 tCO₂e, effective price €64.00, liability €98,124.00, average €64.00 per certificate.
  • 400 t aluminium, 1.40 tCO2e/t, €90 price, no free allocation, no foreign carbon price ⇒ Gross and payable 560.00 tCO₂e, liability €50,400.00, €90.00 per certificate.

FAQ

Which period should the EU ETS price represent?

Use the average weekly price published by the European Commission for the reporting quarter. Keep documentation because customs authorities may request the price source.

How do indirect emissions factor in?

Include both direct process emissions and eligible indirect electricity emissions in the embedded intensity. If you lack supplier data, apply EU default values but document the fallback.

Can the domestic carbon price exceed the EU price?

The credit cannot reduce liability below zero. Enter the effective price you can substantiate; the calculator automatically floors the result at €0 per tonne.

Additional Information

  • Result unit: EUR of CBAM certificates payable for the reporting window.
  • Free allocation percentage reduces the embedded emissions before pricing.
  • Foreign carbon price is capped at the EU ETS price—excess credits do not generate refunds.
