EU Carbon Border Adjustment Mechanism · live since January 2026

Your buyer needs a carbon number. Your suppliers don't have one.

If you ship steel, aluminium, cement or fertiliser into the EU, your importer must declare the emissions embedded in it. With no data from you they use the Commission's default values, which are marked up on purpose. That cost comes back to you as a lower price or a lost order.

How it works

The hard part isn't the maths. It's the phone calls.

  1. 01

    Add your plant

    Fuel, electricity and output for the period. Standard method or mass balance for an integrated works. Every figure keeps the formula that produced it.

  2. 02

    Get your monitoring plan

    Mandatory, and the Commission publishes no template. Answer what only you know and the plan writes itself, with every missing element named.

  3. 03

    Hand over the pack

    Plan, figures, sources, calculation trail and every gap declared up front — the file an accredited verifier audits and your buyer files.

What we are not

Verdex does not certify anyone's emissions.

Under CBAM, actual emissions count only once a verifier accredited by an EU or EEA national accreditation body has signed them. We prepare the evidence that verifier audits, and we say so on every page. Anyone promising you a certificate the EU accepts directly is selling you something that does not exist.

Before you trust a single number: every field we collect and the rule behind it, and two reference plants worked by hand so you can check the arithmetic yourself.

Your first declaration covers 2026. It is filed in September 2027.

The data has to come from a period that has already started. Suppliers take months to answer.
