What CBAM Transitional Registry environments are available?
There is a production and a conformance CBAM registry environment available for CBAM reporting declarants.
The conformance environment can be used as test environment for familiarisation with the CBAM quarterly report form and the user interface of the CBAM Registry.
A separate registration is required (same email may be used) in each environment for security reasons. For both environments, it is the respective NCA that provides reporting declarants with the access details.
