The Carbon Border Adjustment Mechanism (CBAM) in a nutshell
The CBAM is a central pillar of the EU’s flagship climate program, the “Fit for 55” package. The regulation, which has been in force since October 2023, mandates EU-based importers of selected products to report on their emissions. At a later stage, it will also impose a carbon price on these imports. Building on the existing EU Emissions Trading System (EU ETS), the CBAM aims to equalize the cost of manufacturing between EU and non-EU manufacturers of emissions-intensive goods, prevent carbon leakage and galvanize momentum for climate action outside the EU.
Which products fall under the CBAM?
As of today, goods from six sectors, as well as certain precursors and downstream products, are covered: Aluminum, Cement, Electricity, Fertilizers, Hydrogen, and Iron and Steel. However, Article 67 of the CBAM Regulation states that the EU Commission shall pursue the inclusion of additional industries by 2030 to align its scope with that of the EU ETS.
Affected products are determined by their CN code during the customs procedure. While procurement data can be helpful in identifying relevant goods, only customs declaration data is deemed suitable for final classification. Companies should therefore compare the 8-digit CN code of their customs declarations with the list of CN codes provided in Annex 1 of the CBAM Regulation. There are only few exceptions, such as imports from EFTA countries and consignments with a value of less than €150.
Who is directly affected?
The regulation directly affects importers and customs representatives who import CBAM goods into the customs territory of the Union. Throughout the transitional phase from 2023 to 2025, their main responsibility is to comply with the quarterly reporting requirements mentioned above. On January 1, 2026, the implementation phase will begin, introducing a carbon price on the embedded greenhouse gas (GHG) emissions of imported goods. In-scope importers will have to purchase and surrender CBAM certificates, which are modeled on the EU ETS cap-and-trade system.
The past few months have shown that large manufacturers such as wind turbine producers, iron and steel wholesalers, the automotive industry and toolmakers are among the industries particularly impacted by the CBAM. As the regulation provides for very few exemptions, small traders and SMEs are also subject to the CBAM, even if they only import small quantities of covered products.
The intricate role of suppliers
The regulation also indirectly affects all non-EU suppliers of CBAM goods. According to the EU, they should monitor product-related GHG emissions at their production sites and report them to EU importers. Local operators of such production sites are expected to follow a dedicated EU methodology for emissions monitoring, starting in 2025 at the latest. It is important to note that the CBAM Regulation does not stipulate any reporting obligations for third-country suppliers. EU importers of in-scope products are therefore dependent on their voluntary support.
To date, there is no clear guidance from the European Commission and national authorities on how to deal with cases of non-cooperation. The Commission has published guidelines and templates to support both importers and manufacturers. A key recommendation is, for instance, to include a specific clause on the sharing of GHG emissions data in purchasing agreements.
Challenges and lessons learned
Almost ten months into the transitional phase, with the first two mandatory quarterly reports submitted and the third report due by the end of July, it is a good time to take stock and look at the main challenges companies have been facing so far.
1. Complex data management
A key pain point for many companies is the significant effort required to collect and manage data from multiple sources.
- Internal coordination: EU importers need to coordinate processes across internal departments such as customs, procurement, and sustainability to gather the required data. Various data points such as the article type, weight, aggregated goods category, country of origin, spend, CN code, and responsible customs representative need to be collected across entities.
- Need for supplier-specific data: Starting with the fourth quarterly report, due by October 31, companies are required to gather primary emissions data from their suppliers and can no longer rely on default values. Exceptions apply for complex goods. Emissions are calculated at the product level. This includes direct emissions from the production process itself and the manufacturing of certain precursors, as well as indirect emissions from electricity consumption.
2. Resource-intensive reporting process
The transitional phase of the CBAM, which began on October 1, 2023, mandates companies to report the GHG emissions embedded in imported goods on a quarterly basis. The first two reports have been particularly challenging for the following reasons:
- Lack of automation: Many companies reported that delivering the first quarterly report was a highly manual and therefore time-consuming and resource-intensive process. Without automated systems, companies had to rely on spreadsheets and manual data entry, increasing the likelihood of errors and inconsistencies.
- Arduous data collection and reporting: The effort to compile the necessary data, verify its accuracy, and format it according to the data structure required by the EU’s Transitional Registry strained company resources, diverting them from other critical business activities and more strategic tasks.
3. Communication with suppliers
Effective communication and the continuous exchange of data are key to implementing the CBAM, but these processes present significant challenges.
- Lack of standardization: Companies use different methods to request emissions data from their suppliers. While some rely on the voluntary yet complex EU template, others draw on customized spreadsheets or other tools. This lack of standardization can lead to confusion and inefficiency.
- Supplier cooperation: The CBAM Regulation does not impose any legal obligations on third-country suppliers. This can severely compound cooperation and, as a result, EU companies often struggle to obtain the reliable emissions data they need to ensure CBAM compliance.
4. Incomplete or incorrect data
The quality and completeness of supplier data is critical to meeting CBAM reporting requirements. However, the information provided by suppliers often falls short of expectations:
- Insufficient data quality: Suppliers, especially those unfamiliar with complex emissions accounting methodologies, may provide data that is incomplete or of poor quality. This requires importers to manually correct or supplement the information, further increasing the workload and risk of inaccuracies.
- Cost implications: When the implementation phase begins in 2026, the lack of high-quality supplier data can also have financial impacts. Importers will be required to purchase CBAM certificates based on the GHG emissions data provided. Incomplete or inaccurate data could lead to higher costs for these certificates, directly affecting the financial liabilities of companies.
Overall, the CBAM is much more than a mere reporting exercise for EU companies. It has major implications for international supply chains and its success depends largely on close cooperation between importers, distributors and suppliers across different tiers. All these actors must be able and willing to collaborate and share data with one another on an ongoing basis. Capacity-building, engagement, new incentives and contractual obligations are just some of the tools available to EU companies to make sure they meet the requirements.
