On 9 September 2026, the UK government published a comprehensive policy summary for the UK Carbon Border Adjustment Mechanism (CBAM), scheduled to take effect from 1 January 2027. The CBAM will apply a carbon price on imports of specified goods from the aluminium, cement, fertiliser, hydrogen, and iron & steel sectors to address carbon leakage risk as the UK transitions to net zero. The policy summary details the mechanism’s design, including the default emissions values, the role of the UK Emissions Trading Scheme (ETS) price, and the registration and reporting obligations for importers. A consultation on the detailed implementation regulations is expected later in 2026. This measure aligns with the EU CBAM but features UK-specific design elements.
Key Takeaways
- Scope Confirmed for Five High-Emission Sectors: The UK CBAM will initially cover aluminium, cement, fertiliser, hydrogen, and iron & steel imports, with liability based on embedded emissions and the UK ETS carbon price differential.
- Importer Registration and Reporting Obligations: UK importers of CBAM goods must register with HMRC, report quarterly on embedded emissions, and surrender CBAM certificates reflecting the carbon price gap, creating new compliance burdens for supply chains.
- Default Emissions Values and Verification Framework: The policy establishes default emission factors for use when actual data is unavailable, with a pathway for verified actual emissions reporting to reduce liability, incentivising supply chain decarbonisation.
