Obtaining supplier data
Real emission data sits not with you but with the producer of your goods. Obtaining it is the step where the CBAM most often stalls in practice. It is work of communication and persistence.
- The relevant data sits with the producer, often several stages away.
- Collection takes weeks, not days.
- Responses must be sense-checked and brought into a consistent form.
Which data you need
To calculate embedded emissions you need details on the production installation, the production route and the specific emissions per tonne of goods. Depending on the product group that includes direct process emissions and, for electricity-intensive products, the underlying electricity mix. These details come from the producer, not from your own files.
Why it takes time
Suppliers often sit in other countries, speak other languages and hold different views on what they will release. Some data does not yet exist in the form required. Weeks pass before a complete, reliable answer is in hand. Start just before a deadline and you have lost, and you land on default values.
Sense-check, do not copy blind
A response is not automatically usable. Values must be checked for plausibility, brought into a consistent form and filed in the data room. A figure with no traceable origin helps little when the authority asks. Structure and verifiability matter here just as much as the number itself.
