EU CBAM compliance: The do’s and don’ts

This guide is designed to help businesses navigate CBAM compliance in practical terms. It highlights key areas to focus on, common pitfalls to avoid and sensible actions that can reduce both cost and disruption.

Compliance with the EU Carbon Border Adjustment Mechanism (CBAM) is fast becoming a practical reality for businesses trading with the European Union. As CBAM moves from a reporting‑only measure to a system with real financial consequences, understanding what good compliance looks like – and where the risks sit – is essential.

What are my CBAM compliance responsibilities?

Although CBAM is an EU regulation and soon to be UK one, compliance does not sit solely with EU importers. In practice, non‑EU suppliers play a critical role. EU importers depend on accurate and timely information from their suppliers to meet their own legal obligations.

If you export CBAM‑covered goods, you should expect to be asked for detailed information on production processes, embedded emissions and any carbon price already paid. Failing to understand or support these requirements can directly affect your commercial relationships with EU customers. Worth noting that there is no obligation on the Non-EU supplier to provide this information, however EU importers require this, so without the required data the EU importer will be penalized with default data which will severely impact their business commercially, and may result in them looking to other suppliers who can provide the needed data.

What are the key CBAM compliance risks I should watch out for?

One of the most significant risks is poor‑quality emissions data. Where data is incomplete, inconsistent or unsupported, EU importers may be forced to rely on default values. These are typically higher than actual emissions and can increase the overall CBAM cost attached to your goods quite substantially. Another common risk lies in assumptions about responsibility. Many businesses assume CBAM is ‘the importer’s problem’ and delay engagement. In reality, a lack of supplier cooperation can result in pressure on pricing, contract renegotiation or even loss of EU business.

There is also a risk in treating CBAM as a one‑off exercise. Reporting is ongoing, methodologies may change and the scope of CBAM is expected to expand in 2028. Compliance needs to be built into business‑as‑usual processes rather than handled reactively. Businesses that are planning and engaging with suppliers now are at an advantage to those who are waiting to closer to the deadline to act.

What are the do’s of CBAM compliance?

  1. Do take time to understand whether your goods fall within the scope of CBAM and how they move into the EU market. Knowing where CBAM applies – and where it does not – is the foundation of effective compliance. Audit check your commodity codes; you may not be aware that CBAM actually affects you and your business.

  2. Do engage early with internal teams and suppliers to gather emissions data. Clear documentation of how emissions are calculated will make reporting more efficient and reduce the risk of challenge or correction.

  3. Do maintain records. Emissions data, methodologies, assumptions and supporting evidence should be retained in case of queries from EU importers or authorities.

  4. Do review contracts and commercial terms. CBAM introduces new costs and administrative burdens, and these should be clearly addressed in agreements with EU customers where possible.

What are the don’ts of CBAM compliance?

  1. Don’t rely on default values unless absolutely unavoidable. They are designed to discourage poor data quality and can materially increase CBAM exposure.

  2. Don’t underestimate the time and resource required. Collecting emissions data and ensuring it meets CBAM standards can be complex, particularly where supply chains are long or international.

  3. Don’t assume CBAM requirements will remain static. The scope is expected to widen and rules will continue to evolve. A ‘wait and see’ approach increases compliance risk over time.

How can I embed CBAM into my wider business planning?

Strong CBAM compliance is not just about meeting regulatory requirements. It can also support wider sustainability objectives, improve transparency across supply chains and strengthen relationships with EU customers.

Businesses that integrate CBAM into governance, compliance and sustainability planning are better placed to respond as carbon‑based measures become more prominent in international trade.

What should I do now to get ready for CBAM?

  • Confirm whether any goods you supply or import to the EU fall within the current scope of CBAM and understand how responsibility is shared between you and your EU customers.

  • Put processes in place to collect, check and retain emissions data in a consistent and auditable way. This includes engaging proactively with upstream suppliers where necessary.

  • Assess whether your existing contracts adequately address CBAM‑related reporting obligations and costs, as the definitive (liability) phase is now live from 1 January 2026.

Given the technical nature of CBAM compliance and emissions methodology, many businesses are choosing to engage with certified CBAM training or advisory providers. A specialist can help you interpret the rules correctly, build internal understanding and avoid costly compliance errors.
