The European Economic Area (EEA) has advanced the incorporation of the Carbon Border Adjustment Mechanism (CBAM) for Iceland and Norway, although the relevant decisions still require outstanding constitutional and administrative steps before the framework becomes fully operational.
The EEA Joint Committee adopted Decisions 283/2026 and 287/2026 on 25 September. EFTA’s legal database records their entry into force as pending fulfilment of the applicable constitutional requirements, meaning the decisions should not be treated as immediately operational.
The arrangements provide for incorporation of the CBAM framework and related systems into the relevant EEA arrangements. Liechtenstein is excluded from this incorporation arrangement, so the development should not be characterised as a uniform CBAM extension across all EEA countries.
Norway and Iceland remain at different stages
The Norwegian government said its parliament had already approved the relevant incorporation in June, while parliamentary approval in Iceland was still outstanding.
Norway is preparing for CBAM application from 2027, but adoption of the EEA Joint Committee decisions does not mean that every domestic implementation requirement has already been completed.
The distinction is relevant for companies preparing for cross-border trade. Formal adoption of an incorporation decision does not automatically make every registry function available or complete all application and administrative procedures.
Importers will need to follow the effective legal dates and instructions issued by the competent authority in the jurisdiction concerned.
Declarant authorisation becomes part of business preparation
Norway’s announcement also addressed preparations for CBAM declarant authorisation, placing attention on the practical sequence of business registration and administrative readiness.
Companies should therefore not assume that an existing EU CBAM account automatically satisfies the requirements applicable in another jurisdiction.
For businesses managing Nordic and wider European supply chains, the EEA decisions provide greater clarity on the intended legal direction while leaving differences in the timing of operational implementation.
Constitutional approval remains a key milestone
The next steps are the completion of the outstanding constitutional process and publication of the remaining practical arrangements.
Until those steps are completed, the legal position is best described as adopted incorporation decisions awaiting entry into force, rather than a completed expansion of all CBAM procedures across the relevant jurisdictions.
