The ID used in the CBAM Report and the ID you use internally in the platform are different because they serve different purposes.

If you upload imports' data before your supplier accepts the connection, the data will be saved, but you won’t be able to retrieve actual emissions data from that supplier until the connection is accepted.

Once the connection is accepted, the emissions values will be automatically updated for all imports referencing that supplier. Please verify that the values have been updated correctly.

If the newly connected supplier has two installations producing CBAM goods with the same CN code as the ones you imported, a message will prompt you to manually select the installation that produced the CBAM good you imported.

If a connected Supplier modifies a diagram that was previously saved as final, and for which emissions data has already been shared with the CBAM Declarant, the emissions values will be automatically updated to reflect the new data. As a result, all associated imports will be updated with the new values. The CBAM Declarant will be able to view the updated values in their account.

Any new CBAM reports generated will include the updated emissions values, while reports generated before the data update will retain the previous values.

If transformation processes occur in secondary installations or are outsourced to other companies and the goods are subsequently returned to the primary installation, they may be treated as if they happen in the primary installation.

You can represent these processes as sub-processes in your diagram and specify that they were outsourced, as shown in the diagram below.

You should use the Notes field to provide any additional information, such as assumptions used to calculate the total net mass produced or other relevant details.

For instance, if you started tracking the net mass production of your CBAM goods in June 2023, explain the assumptions you used to estimate production for the previous months of 2023. Explanations should be clear enough for a third party to understand the assumptions made and how values were derived.

Use the Notes section to specify any alternative data sources you used for the calculation factors, such as the net calorific value (NCV) and emission factor. If applicable, also use this section to explain any assumptions you made regarding the quantity of fuel consumed during months in which you could not gather accurate records.

Additionally, indicate how the quantity of fuel consumed was determined (e.g., invoices from your fuel supplier, purchase records and stock measurements, metering equipment at the installation, etc.)

Ensure that your explanations are detailed and clear enough for a third party to understand any assumptions made and how the values were calculated.

Use the Notes section to specify any alternative data sources you used for the electricity emission factor. If applicable, also use this section to explain any assumptions you made regarding the quantity of electricity consumed during months in which you could not gather accurate records.

Additionally, indicate how the amount of electricity was determined (e.g., invoices from your utility company, metering equipment at the installation, etc.) Ensure that your explanations are detailed and clear enough for a third party to understand any assumptions made and how the values were calculated.
