What CBAM will cost you, and what you still do not know

Enter the goods you import into the EU. This tool tells you whether you cross the 50 tonne de minimis threshold, prints the certificate cost arithmetic one step at a time from figures you supply, and refuses to invent the emissions figures you do not have. Where a number is missing it names the number, names who holds it, and gives you a list you can send to the supplier.

01Year and carbon price

Indicative only. Replace it with the figure your treasury uses.

02Line items

Imported line items

Quantity is net mass in tonnes, except electricity, which is entered in megawatt hours. This tool does not classify goods. Confirm the CN code of each product against Annex I of the Regulation and the current TARIC entry before you rely on any of this.

06What you must do and when

    07Export and share

    Supplier data request

    One row per line item, with the emissions figure where you have it and a plain statement of what is missing and who holds it where you do not. Column headings are written so that a procurement team can send the file to a supplier without editing it.

    08Method and sources

    Every regulatory figure this tool uses is listed below with the value, the source and the date the source was read. Nothing else is hard coded. If a figure below has moved, the tool is wrong and the figure in the current Regulation is right.

    Constants

    Chargeable share of embedded emissions, year by year

    Directive (EU) 2023/959 recital 46 and Article 10a(1a) of Directive 2003/87/EC eur-lex.europa.eu checked 2026 08 21
