Frequently asked questions
Is my data uploaded anywhere?
No. The calculator is a static page — parsing, math and the report all happen in your browser. There is no server-side form handler at all.
How accurate is the estimate?
The arithmetic is exact; the inputs carry the uncertainty. Certificate prices move weekly, intensities vary by installation, and rules evolve — hence the range and the disclaimers.
Is this legal or compliance advice?
No. It is an estimation and education tool. Official rules, default values and prices are published by the European Commission; verify before filing or contracting.
What goods does CBAM cover?
Cement, iron and steel, aluminium, fertilisers, electricity and hydrogen, plus a range of downstream products — check the CN-code lists in the official legislation for your exact goods.
Why is a free tool doing what consultancies charge for?
The arithmetic is public and mechanical. Consultancies sell assurance and filing work; a transparent estimator with editable, sourced assumptions covers the planning use-case.
