The emissions questionnaire you send to suppliers

View as Markdown

Carbon border reporting needs emissions figures that only your supplier has. Rather than asking for them by email and retyping the answers, you send a link to a questionnaire they fill in themselves.

This page is about that questionnaire. Your supplier uses it; you send it and read the results.

Each questionnaire has its own address under /cbam/supplier/ followed by a unique token.

The token is the credential. There is no sign-in, no account and no password: whoever holds the link can fill the form in. Treat it accordingly. Send it to the person who should answer, and do not post it anywhere public.

The address is checked strictly before anything loads, so a mangled or guessed link fails immediately rather than reaching the platform.

What your supplier sees

The page shows the context of what they are being asked about, including the “ASN”, the “Product”, the “HS code”, the “Qty shipped” and the “CBAM scope”, so they know which shipment this concerns.

They then fill in the emissions data:

  • the direct emissions figure, in tonnes of CO2 equivalent per tonne, which the form marks as required
  • “Indirect emissions (tCO₂e per tonne)”
  • “Production route”, with an example appropriate to the goods, such as steel, aluminium, cement, fertiliser, electricity, hydrogen or iron
  • “Operator installation ID”
  • “Carbon price already paid (€ per tCO₂e)”
  • “Precursor materials”, which they can add if relevant
  • “Supporting notes”

Then “Submit emissions data”.

The form validates as they go, so an impossible figure is caught in front of them rather than accepted and rejected later.

Reading what comes back

Submitted figures land in the CBAM view of “Freight & customs”. See Freight and customs.

Practical advice

Send the link to a named person, not a shared inbox, because the link is the credential and a shared inbox spreads it. If a supplier says the link does not work, re-issue rather than debugging the address by hand: a truncated link is the usual cause and a fresh one costs nothing.
