The UK’s Carbon Border Adjustment Mechanism (CBAM) is coming, and it’s going to reshape how businesses think about imports, costs, and supply chains.
From 1 January 2027, UK importers of certain carbon-intensive goods will face a new tax based on the emissions embedded in those products. While this initially targets sectors like steel, aluminium, cement, fertilisers, and hydrogen, the reality is much broader: the cost and compliance impact will ripple across entire supply chains.
This isn’t just an environmental policy, it’s a commercial and operational shift that businesses need to prepare for now.
Why CBAM Matters
The mechanism is designed to prevent “carbon leakage” where production moves overseas to avoid stricter UK climate policies.
In practice, it means imports will be taxed to reflect the same carbon cost faced by UK producers under the UK Emissions Trading Scheme. The tax is administered by HM Revenue & Customs and calculated using the emissions embedded in the imported goods.
For businesses, that translates into:
- Rising input costs
- Increased scrutiny on supply chains
- New reporting and compliance obligations
It’s Not Just Importers Who Are Affected
Even if you’re not directly importing CBAM goods, you’re unlikely to avoid the impact.
Construction & Infrastructure
Steel, cement, and aluminium costs are expected to rise—affecting everything from structural builds to large-scale infrastructure projects.
Manufacturing
Automotive, aerospace, and engineering sectors will see increased costs on key materials, especially where sourced from outside the UK or EU.
Agriculture & Food
Fertiliser costs will rise, creating knock-on effects for food production and pricing.
Packaging & FMCG
Aluminium packaging – including cans and foil – will carry additional cost pressures.
In short: CBAM costs will move through the supply chain, not stop at the border.
The Key Commercial Risks
Businesses should be particularly aware of:
- Cost uncertainty as carbon pricing evolves
- Supplier risk where emissions data is unavailable
- Contract exposure if CBAM costs aren’t clearly allocated
- Compliance penalties for incorrect classification or reporting
There’s also a short-term market dynamic to watch: a potential influx of high-carbon goods into the UK before 2027, as suppliers adjust to earlier EU CBAM implementation.
What You Should Be Doing Now
With the first reporting period starting in 2027 (and payments due in 2028), preparation time is limited.
Key actions include:
- Reviewing your import classifications and exposure
- Engaging suppliers on emissions data
- Assessing whether you’ll exceed the £50,000 registration threshold
- Building CBAM costs into pricing and procurement strategies
- Reviewing contracts for cost pass-through clauses
Early preparation will be the difference between controlled adaptation and reactive disruption.
