Carbon Border Adjustment Mechanism (2025)

The EU’s Carbon Border Adjustment Mechanism (CBAM) is the EU's tool to put a fair price on the carbon emitted during the production of carbon intensive goods that are entering the EU, and to encourage cleaner industrial production in non-EU countries.

By confirming that a price has been paid for the embedded carbon emissions generated in the production of certain goods imported into the EU, the CBAM will ensure the carbon price of imports is equivalent to the carbon price of domestic production, and that the EU's climate objectives are not undermined. The CBAM is designed to be compatible with WTO-rules.

CBAM will apply in its definitive regime from 2026, while the current transitional phase lasts between 2023 and 2025. This gradual introduction of the CBAM is aligned with the phase-out of the allocation of free allowances under the EU Emissions Trading System (ETS) to support the decarbonisation of EU industry.

CBAM definitive regime (from 2026)

• 

  EU importers of goods covered by CBAM will register with national authorities where they can also buyCBAM certificates.The price of the certificates will be calculated depending on the weekly average auction price of EU ETS allowances expressed in €/tonne of CO₂emitted.

• 

  EU importers willdeclare the emissions embedded in their imports and surrenderthe corresponding number of certificates each year.

• 

  If importers can prove that a carbon price has already been paidduring the production of the imported goods, the corresponding amount can be deducted.

On 1 October 2023, the CBAM entered into application in its transitional phase, with the first reporting period for importers ending 31 January 2024. The gradual phasing in of CBAM allows for acareful, predictable and proportionate transition for EU and non-EU businesses, as well as for public authorities.

The CBAM willinitially apply to imports of certain goods and selected precursorswhose production is carbon intensive and at most significant risk of carbon leakage:cement, iron and steel, aluminium, fertilisers, electricity and hydrogen. With this enlarged scope, CBAM will eventually – when fully phased in – capture more than 50% of the emissions in ETS covered sectors. The objective of the transitional period is to serve as a pilot and learning period for all stakeholders (importers, producers and authorities) and to collect useful information on embedded emissions to refine the methodology for the definitive period.

During this period, importers of goods in the scope of the new rules will only have to report greenhouse gas emissions (GHG) embedded in their imports (direct and indirect emissions), without the need to buy and surrender certificates. Indirect emissions will be covered in the scope after the transitional period for some sectors (cement and fertilisers), on the basis of a defined methodology outlined in the Implementing Regulation published on 17 August 2023 and its accompanying guidance.

The Implementing Regulation on reporting requirements and methodology provides for some flexibility when it comes to the values used to calculate embedded emissions on imports during the transitional phase. Until the end of 2024, companies will have the choice of reporting in three ways: (a) full reporting according to the new methodology (EU method); (b) reporting based on an equivalent method (three options); and (c) reporting based on default reference values (only until July 2024).

As of 1 January 2025, several changes will be introduced:

With regards to the reporting, only the EU method will be accepted. For complex goods, estimates (including default values) can only be used if they account for less than 20% of the total embedded emissions. The Commissionpublished default valueson 22 December 2023.This reportfrom the EU’s Joint Research Centre (JRC) fed into the preparation of those default values.

Furthermore, a new portal section of the CBAM Registry will allow installation operators outside the EU to upload and share their installations and emissions data with reporting declarants ina streamlined manner, instead of submitting it to each declarant separately. The portal will allow operators to ensure the confidential treatment of business-sensitive data. Reporting declarants will then be able to automatically populate their CBAM reports with this emissions data in order to comply with their reporting obligation. Registration for installation operators will open from 1 January 2025.

Finally, CBAM declarants will be able to apply for the ‘authorised CBAM declarant’ status via the CBAM Registry. Their application will be processed by the National Competent Authority of the EU Member State where they are established. This status will become mandatory as of 1 January 2026 for the import of CBAM goods in the EU customs territory.

A review of the CBAM's functioning during its transitional phase will be concluded before the entry into force of the definitive system. At the same time, the product scope will be reviewed to assess the feasibility of including other goods produced in sectors covered by the EU ETS in the scope of the CBAM mechanism, such as certain downstream products and those identified as suitable candidates during negotiations. The report will include a timetable setting out their inclusion by 2030.

Where to report

The Commission has developed the CBAM transitional registry to help importers perform and report as part of their CBAM obligations. Access to the registry should be requested through the National Competent Authority (NCA) of the Member State in which the importer is established.

CBAM Transitional Registry – Link for importers

The provided link is accessible solely to importers who have been duly registered by the relevant National Competent Authorities.

If you haven't yet registered and you wish to access the registry, kindly reach out to the NCA of your respective Member State. Otherwise, unauthorised access to the registry is prohibited.

CBAM reporting declarants will find in the CBAM Transitional Registry User Manual an XSD file describing the full structure of the CBAM quarterly report, as well as a sample ZIP file, which may be uploaded in the Registry to fill in automatically the quarterly report’s data. For convenience, the XSD and the sample ZIP files can also be downloaded below.

In addition, the Commission has prepared a specific guidance document for declarants, which outline the functioning and step-by-step use of the “request delay” options in the CBAM Transitional Registry.

The CBAM Transitional Registry is continuously enriched with IT updates and fixes (see attachment below for the latest update).

As of October 1st, Release 1.3.1.0 is in production. The latest features are highlighted in the slide below.

Quarterly Report

This XLS file can be used by CBAM Declarants to facilitate completion of the CBAM quarterly reports using XML files. The XLS file indicates which are the optional/mandatory fields and provides the pre-defined values that are allowed for specific fields.

Furthermore the “Error Messages Glossary” tab is providing guidance on how the user can overcome the validation error messages displayed whenever a validation rule/condition is triggered due to an issue with the field values filled/selected by the user.

How to access the transitional registry

Access to the Transitional CBAM registry should be requested through the National Competent Authority (NCA) of the Member State in which the importer is established.

Guidance

The Commission has developed a CBAM Self Assessment Tool for Importers to the EU. The tool provides importers to the EU with the possibility to get a quick overview on whether the imported goods are subject to CBAM during the transitional period, what the CBAM reporting requirements for that particular type of good are, and where to find further information.

The European Commission maintains the tool to facilitate the implementation of the CBAM during the transitional period until 31 December 2025. The goal is to keep the tool timely and accurate, and if errors are brought to our attention, we will try to correct them. However, the Commission accepts no responsibility or liability whatsoever with regards to the information provided by this tool. It cannot be guaranteed that the tool exactly reproduces the officially adopted legislation. Only the Official Journal of the European Union (the printed edition or, since 1 July 2013, the electronic edition on the EUR-Lex website) is authentic and produces legal effects.

Further information on customs obligations for importers to the EU are provided by the TARIC database.

To help stakeholders prepare for the new reporting obligations as from 1 October 2023, the European Commission has prepared written guidance documents, to help navigate the transitional period (1 October 2023 – 31 December 2025).

The Guidance document on CBAM implementation for installation operators outside the EU is also available in Arabic,Chinese, Hindi, Korean, Ukrainian and Turkish.

The Commission has published the default values guidance that can be used to determine embedded emissions in imported goods (except electricity) covered by the CBAM.

The Commission has prepared a Q&A document which provides answers to the most frequently asked questions about the CBAM. This document will be continuously updated:

The European Union is committed to supporting developing countries and Least Developed Countries (LDCs) in implementing the CBAM, greening their industries, and transitioning to renewable energy sources. The EU is also committed to help those countries interested in introducing or enhancing their carbon pricing systems. The following document provides an overview of guidance and technical support offered by the EU as well as of programmes supporting the green transition in developing countries and LDCs.

Sectoral information

The Commission organised a series of online webinars, covering general features of the CBAM as well as the specifics of each sector (iron & steel, aluminium, cement, fertilisers, electricity and hydrogen). Details and recordings of all webinars are available below and on the.

Information relevant to all sectors

In addition, anano-learning moduleintroducing CBAM for EU importers and customs declarants and third country operators has been made available.They presentthe purpose and aims of CBAM, and implications for importers and declarants, the main criteria for CBAM pricing, the six sectors targeted by CBAM and the roles and responsibilities within the CBAM administration system, as well asplanning priorities including key milestonesand explains the calculation methods and reporting requirements.
