Understanding the New EU CBAM Guidance for Overseas Manufacturers

As EU CBAM moves into its definitive phase, overseas manufacturers are increasingly being asked to provide emissions data by their EU customers. The European Commission's latest guidance aims to clarify what information is required, how emissions should be calculated and what businesses need to do to support compliance.

The EU Commission has released a new series of documents to help businesses navigate the EU Carbon Border Adjustment Mechanism (CBAM).

While the EU CBAM has now moved into its definitive phase, following a long introductory transitional phase since Q4 2023, uncertainty remains, especially amongst non-EU manufacturers on what this means for them.

How does the EU CBAM impact overseas manufacturers?

The EU CBAM applies a carbon cost on carbon-intensive imports into the EU.

Since 1 January 2026, EU businesses importing over 50 tonnes of in-scope goods are required to comply with CBAM requirements. This includes registering as a CBAM Authorised Declarant and submitting annual CBAM declarations.

While the obligation and financial burden falls on the importer, a significant portion of the work actually falls on the overseas manufacturer, as they are the only party able to collect the required emissions data.

There are two main types of CBAM data:

  • Actual emissions data: monitored at the source by the manufacturer and verified by an accredited third party.
  • Default values: provided by the European Commission to be used as a last resort when actual data is unavailable.

The framework is designed to incentivise the use of actual emissions data, while the use of default values can result in a higher CBAM liability for importers.

As a result, EU importers are increasingly asking their overseas suppliers for verified emissions data.

However, this can represent a significant new administrative and technical challenge for manufacturers operating in countries where carbon reporting and pricing requirements are less developed. This has led to a growing amount of confusion, which the EU Commission is trying to address through its guidance documents.

What’s included in the EU Commission’s guidance?

The EU Commission has structured its guidance in an accessible manner, splitting it into five key areas:

    1. Introduction to CBAM concepts
    2. Quick guide for non-EU operators on CBAM implementation
    3. CBAM methods for calculation of embedded emissions
    4. CBAM calculation of the free allocation adjustment
    5. Sector-specific guidance

Together, these documents provide a clear step-by-step framework for understanding what CBAM means for manufacturers and how the required emissions data can be calculated and reported.

Collectively, the guidance provides practical support for manufacturers, helping them understand CBAM reporting requirements and the emissions data their customers may request.

Each guidance document is linked above so it can be shared directly with overseas suppliers to help them understand what their EU customers are asking them to provide.

FAQs

The EU Carbon Border Adjustment Mechanism (CBAM) is designed to apply a carbon cost to certain imported goods entering the EU. Its objective is to reduce carbon leakage and create a more level playing field between EU producers and overseas manufacturers.

The reporting obligation sits with the EU importer. However, overseas manufacturers are often responsible for providing the emissions data needed for compliance.

Businesses need to provide embedded emissions data for in-scope goods. The EU framework encourages the use of verified actual emissions data wherever possible.

Default values are emissions factors provided by the European Commission that can be used when actual emissions data is unavailable. However, using default values can lead to higher CBAM liabilities.

Although the legal obligation sits with EU importers, manufacturers are typically the only organisations able to collect and provide the emissions data required for CBAM reporting.

The European Commission has published a suite of guidance documents covering CBAM implementation, emissions calculations and sector-specific requirements.
