The European Union’s Carbon Border Adjustment Mechanism (CBAM) is set to reshape the way carbon-intensive goods are imported into the EU. For UK businesses that export affected products to the bloc — such as iron, steel, aluminium, fertilisers, and cement — understanding the rules and preparing for CBAM compliance is now a pressing issue. Failure to comply could result in serious penalties, delays at borders, or reputational risk.
CBAM aims to level the playing field by applying a carbon price to imported goods equivalent to the EU’s internal carbon pricing system. In effect, it holds foreign producers to the same environmental standards expected of EU-based manufacturers. As of 2025, the financial implications of CBAM will begin to take effect, following the current transitional phase that started in October 2023.
So, how can your business stay ahead and avoid falling foul of CBAM rules? Below are the key steps you should be taking now.
1. Identify Affected Products in Your Supply Chain
The first step in CBAM compliance is knowing which products fall under the regulation. Initially, the mechanism applies to a specific set of carbon-intensive goods — including iron and steel, aluminium, fertilisers, hydrogen, electricity, and cement. Review your product codes (CN codes) and assess whether any items you export to the EU are on the CBAM list.
If your products are affected, begin mapping out where the raw materials originate, what emissions are generated during production, and how they are documented.
2. Collect and Verify Embedded Emissions Data
CBAM requires importers to report on the embedded greenhouse gas emissions in the goods they bring into the EU. During the transitional phase, this data must be reported quarterly — and from 2026, CBAM certificates will need to be purchased to account for those emissions.
Work with your suppliers now to gather accurate and verifiable emissions data. If the data is not available, standard default values may be used — but these often overestimate emissions, which could increase costs unnecessarily.
3. Implement Reporting Processes
CBAM compliance is not a one-off activity. It requires ongoing reporting, data management, and document submission. Establish internal systems or work with a compliance specialist to track and submit the required quarterly reports, which must include:
- The type and quantity of goods imported
- The actual embedded emissions per product
- Verification from an accredited third party (in the future)
Putting these processes in place now will help you avoid last-minute errors or omissions.
4. Prepare for Financial Liabilities
From 2026 onwards, importers will be required to purchase and surrender CBAM certificates, priced according to the weekly average EU Emissions Trading System (ETS) price. Budgeting for these certificates will be essential, especially if your company deals in high volumes of CBAM-covered goods.
Failing to surrender the correct number of certificates could result in penalties of €100 per tonne of CO₂ equivalent — a substantial risk to profit margins and compliance status.
5. Stay Informed and Update Continuously
CBAM will likely evolve over time. New product categories may be added, reporting requirements could change, and enforcement could tighten. To maintain CBAM compliance, businesses must stay informed through trusted legal, trade, or industry sources.
Final Thought
CBAM represents a major shift in how cross-border carbon is priced and regulated. Businesses that take early action to understand and integrate CBAM compliance into their operations will not only avoid penalties but also gain a competitive advantage. The cost of inaction — both financially and reputationally — could be far greater than the investment required to get ahead of the rules.
