The supplier letter

A supplier letter decides whether you get real emission data or silence. Most requests fail not on the supplier but on an unclear, unintelligible or intimidating enquiry.

Why most letters fail

A supplier who gets a vague email with the subject line CBAM often does not know what exactly to deliver, why, or by when. So they do nothing. The most common cause of missing data is not unwillingness but a poor enquiry. Treat the request as a formality and you get formal non-answers.

What belongs in it

An effective letter names the wanted data points concretely, ideally in a fillable format. It explains briefly why the data is needed and what advantage correct values hold for the business relationship too. It states a realistic but clear deadline and a contact for questions. And it is written in a language the supplier understands.

Multilingual and followed up

Source from several countries and you need the letter in several languages. Just as important is the follow-up: a single email rarely suffices. Reminders, queries and the closing of gaps are part of the process. Within the CBAM Decision File and the Supplier Data Sprint we deliver ready-made, multilingual templates and, on request, take on the follow-up.
