EU carbon border levy hits New Zealand aluminium exports: competitiveness and CBAM explained

The EU's Carbon Border Adjustment Mechanism (CBAM) is now fully in effect for aluminium imports, and New Zealand exporters are feeling the pressure. Since January 2026, EU importers must buy CBAM certificates covering the embedded carbon in products like aluminium. Because New Zealand's domestic carbon price is lower than the EU ETS price, the gap creates a direct cost penalty for NZ producers, making their exports less competitive in the European market. Beyond the certificate cost, the reporting burden is significant. The EU requires companies to calculate embedded emissions using its own methodology, which may not align with New Zealand's existing emissions reporting framework. Independent verification and new registration requirements add further compliance costs. The New Zealand Aluminium Smelter at Tiwai Point, a major industrial facility, is directly affected. There is a potential upside for low-carbon producers. New Zealand's relatively clean electricity grid gives its aluminium a lower carbon footprint than many competitors. If the industry invests in cleaner production and robust emissions tracking, it could turn CBAM into a market advantage. Policymakers are also expected to review CBAM before 2030, with possible expansion into agriculture, so the stakes go beyond metals.
