CBAM Registry and Reporting

CBAM Definitive Registry (from 2026 onwards)

The Commission is developing the CBAM Definitive Registry to help importers perform and report as part of their CBAM obligations during the CBAM definitive regime (from 2026 onwards).

Authorisation Management Module (AMM)

Importers of CBAM goods (or their indirect customs representatives) are urged to apply for the status of authorised CBAM declarants. Please read carefully and follow the instructions below as soon as possible to submit your CBAM application. 

As of 31 March 2025, a new section of the CBAM Registry allows importers and indirect customs representatives to apply for the status of authorised CBAM declarant in the Member State of establishment, which is independently from the where the goods are imported to. A list of the national competent authorities can be found on this website in the section “How to access the transitional registry”. 

The section to be used is the Authorisation Management Module (AMM) (this link will be accessible on 31 March 2025). The AMM encompasses features related to CBAM Authorisations. This module facilitates the entire process, from the initial authorisation requests submitted by applicants to the consultation process between competent authorities and the Commission, culminating in a decision to grant or refuse the CBAM authorisation.

Module for non-EU installation operators (O3CI)

As of January 2025, a new portal section of the CBAM Registry allows installation operators outside the EU to upload and share their installations and emissions data with reporting declarants in a streamlined manner, instead of submitting it to each declarant separately. 

Please note that there are two main steps, and only by carefully following the instructions below will you be able to successfully connect to the portal.

Step 1: Create an EU Login Account

1. Go to https://webgate.ec.europa.eu/cas.
2. Register using your email address (a company email is strongly recommended), create a password, and confirm your registration via the email link you receive.
3. Set up two-factor authentication (EU Login App, QR code, or FIDO2 key).
4. Each user must register individually.

Step 2: Submit Access Request (Onboarding Wizard)

1. Go to https://cbam.ec.europa.eu/o3cinstallation.
2. Log in using your EU Login credentials.
3. Complete the onboarding form with the following information:
   • Company details and registration number/identifiers
   • Company email and website
   • User role (Admin Operator or Simple Operator)
   • Upload a single PDF containing (documents preferably in English, including a courtesy translation, along with the original documents):
     • Company registration certificate (including registration number/identifier matching the one provided in the form)
     • Proof of representation (e.g., power of attorney)
     • ID of the authorized representative

The relevant section to be used is Operators Third Countries Installations. The portal allows operators to ensure the confidential treatment of business-sensitive data. Reporting declarants are then able to automatically populate their CBAM reports with this emissions data in order to comply with their reporting obligation. 

The portal allows operators to ensure the confidential treatment of business-sensitive data. Reporting declarants are then able to automatically populate their CBAM reports with this emissions data in order to comply with their reporting obligation. 

CBAM declarants can retrieve the information provided by non-EU installation operators in the Transitional Registry.  A new functionality in the “Emissions” tab allows declarants to “Search in Third Country Installations registry” and access the respective installation and emissions data from there. 

For this to work, CBAM declarants need to share their EORI number with the supplier outside the CBAM Registry. In a future update, operators will be given the option to share their information with all interested declarants. 

To become a Registered Operator, non-EU installation operators need to follow the steps outlined in the following e-learning modules and guidance documents.
