Carbon Border Adjustment Mechanism (CBAM)

In 2026, the European Union will flip the switch on one of the most consequential climate policies ever applied to global trade. The Carbon Border Adjustment Mechanism (CBAM) will move from its transitional phase into full operation, fundamentally changing how carbon-intensive goods are priced at the EU’s borders.
For businesses exporting materials such as steel, cement, aluminium, fertilisers, electricity, and hydrogen into the EU—including companies based in the UK—CBAM is no longer a future policy problem. It is an immediate commercial reality that directly affects cost structures, competitiveness, and pricing strategies.
At its core, CBAM is designed to close a long-standing loophole in climate policy: carbon leakage. While EU producers have been subject to carbon pricing through the EU Emissions Trading System (ETS) for years, imports from countries with weaker or non-existent carbon pricing have enjoyed a cost advantage. CBAM seeks to level that playing field.
But the mechanism by which the EU plans to do this is complex—and the implications for businesses are far-reaching.
How CBAM Works in Practice
CBAM places a carbon price on certain imported goods equivalent to what EU producers would pay under the EU ETS. The calculation is based not on estimates or averages, but on verified, product-specific emissions data, measured against EU benchmark standards.
From 2026 onward, importers will be required to purchase CBAM certificates reflecting the embedded emissions of their goods. If a non-EU producer can demonstrate that it has already paid a carbon price in its home country, that amount can be deducted. If it cannot, the full EU carbon cost applies.
In other words, CBAM transforms carbon emissions into a direct trade cost.
During the current transitional phase (2023–2025), companies are required only to report emissions. No payments are due yet. But this reporting period is not a grace period—it is a test run. The quality of data systems, verification processes, and internal carbon accounting put in place now will determine how exposed a business is when CBAM becomes financially binding.
Why 2026 Is a Turning Point?
Once CBAM enters its definitive phase in 2026, carbon reporting failures will no longer be a compliance inconvenience—they will be a commercial liability.
Goods without verified emissions data will be subject to default values, which are intentionally punitive. These default benchmarks assume higher-than-average emissions, meaning that poor data does not result in neutrality, but in higher tariffs.
For exporters operating on thin margins, particularly in commodity sectors like steel or aluminium, this can materially affect competitiveness in the EU market. Carbon intensity will increasingly influence not just sustainability credentials, but contract negotiations, customer preferences, and long-term market access.
The UK and Global Exporters Are Not Exempt
Although the UK has its own Emissions Trading Scheme, it is not currently aligned with the EU ETS. This means UK exporters are treated as third-country suppliers under CBAM rules. Unless equivalence or linkage is agreed, UK firms exporting CBAM-covered goods to the EU will need to comply in full.
The same applies to exporters across Asia, the Middle East, and the Americas. CBAM is WTO-compliant by design, and its reach is explicitly global. Any business selling covered goods into the EU must either prove its carbon footprint—or pay for it.
What CBAM Means for Business Strategy
CBAM is often framed as a regulatory burden, but in reality it is a market signal. Carbon pricing is no longer confined to domestic environmental policy; it is embedded into international trade.
For businesses, this has three immediate strategic implications.
First, carbon accounting becomes a pricing input, not a sustainability add-on. Emissions data must be as robust and auditable as financial data, because it directly affects landed cost.
Second, supply chains matter more than ever. Companies sourcing intermediate materials with high embedded emissions may find themselves exposed even if their own operations are relatively efficient.
Third, low-carbon production is a competitive advantage. Firms that can document emissions below EU benchmarks will pay less—or nothing—under CBAM, positioning themselves more favourably against higher-emitting competitors.
As The Guardian has noted, CBAM marks a shift in how climate responsibility is enforced globally: not through voluntary pledges, but through trade policy with real financial consequences.
Preparing for a Carbon-Constrained Trade Environment
The companies best positioned for CBAM are not waiting until 2026. They are already investing in emissions measurement systems, third-party verification, and operational decarbonisation.
CBAM compliance is not just about avoiding tariffs. It is about maintaining access to one of the world’s largest markets at a time when carbon transparency is becoming a prerequisite for doing business.
In that sense, CBAM is less a border tax and more a preview of the future of global trade—one where carbon intensity is priced, measured, and unavoidable.
For businesses navigating the complexities of CBAM, expert support can make a material difference. We work with exporters and industrial companies to prepare CBAM-compliant emissions data, and develop practical decarbonisation strategies aligned with commercial realities. Whether you are at an early reporting stage or preparing for full financial exposure in 2026, tailored guidance can help reduce risk, protect competitiveness, and turn compliance into a strategic advantage.
