UK CBAM

UK Carbon Border Adjustment Mechanism (UK CBAM)

From 2027, the UK will introduce a Carbon Border Adjustment Mechanism (UK CBAM), to ensure that certain imported goods face a carbon cost comparable to domestic production. The initial scope covers iron and steel, cement, aluminium, fertilisers, and hydrogen, with coverage expected to expand from 2029.

The framework will require importers to settle their obligations through the UK tax system administered by HM Revenue and Customs (HMRC). Goods covered by the UK CBAM will be subject to a financial liability upon import and each covered sector will have its own CBAM rate which will feed into this CBAM liability.

This liability is directly linked to the average of all UK Emissions Trading Scheme (UK ETS) auction clearing prices for the relevant quarter. UKAs represent the right to emit one tonne of carbon dioxide equivalent (CO₂e) under the UK ETS.

Who does the UK CBAM impact?

UK CBAM applies to specific commodity codes from included sectors.

Imports of CBAM-covered goods with a total value of less than £50,000 over the preceding 12-month period are exempt.

Also exempt include goods imported for non-business use, imported scrap products within the aluminium and iron and steel sectors, and, in specific situations, goods exported from Northern Ireland to the EU and then reimported into the UK. Indirect emissions will not be included in CBAM calculations until 2029 at the earliest.

How are UK CBAM liabilities calculated?

The final UK CBAM liability to HMRC is directly linked to the cost of UK Allowances (UKAs), which represent the right to emit one tonne of carbon dioxide equivalent (CO₂e) under the UK ETS.

The formula for calculating this liability is:
Mean average of all UK ETS auction clearing prices for the relevant quarter x Free allocation adjustment = CBAM liability

While the liability associated with UK CBAM is paid directly to HMRC, it is possible to hedge against carbon price volatility inherent in the UK ETS market.

Businesses who hedge their UK CBAM costs benefit from reduced budgeting uncertainty linked to UK CBAM obligations and improved cash-flow and trading flexibility.

How does the UK CBAM impact you?

The UK CBAM fundamentally changes the cost structure for businesses importing carbon-intensive goods into the United Kingdom.

Without careful planning and risk management, failure to adapt may lead to increased costs and potential penalties, with implications for pricing, margins and market competitiveness.

How can you manage UK CBAM obligations?

While the UK CBAM introduces new compliance requirements and cost considerations, exposure can be effectively managed through tailored risk management strategies, supporting more confident financial planning and procurement decisions.
