The EU Council's Ad Hoc Working Party on the Carbon Border Adjustment Mechanism (CBAM) on 1 December 2026 received a presentation from the European Commission detailing a review of CBAM's transitional period and a legislative proposal to extend its scope and strengthen anti-circumvention measures. The proposal, which adds approximately 180 new product codes covering downstream goods like machinery and vehicles, would increase covered import value by about 55% and introduces new rules to close the 'scrap loophole' and reform electricity emission methodologies. This formally launches the co-decision process, with member state delegations now set to scrutinise the economic and administrative impacts.
Commission Proposes Two-Step Roadmap and Legislative Amendments The presentation, serving as a key input for Council negotiations, comprises two main parts: a CBAM Review Report assessing the 2023-2025 transitional period, and a legislative proposal for amendment. The Review Report finds limited economic impact on Least Developed Countries and Ukraine, and proposes a two-step implementation roadmap: first, 2026-2027 proposals on downstream products and anti-circumvention; second, a 2027 report on further extensions to indirect emissions and other sectors like chemicals. The legislative proposal aims to extend CBAM's scope and close loopholes, including downstream extension, anti-circumvention measures (attributing emissions to pre-consumer scrap, enhanced traceability), reformed electricity default factors, and technical improvements such as mandatory registry registration for actual emissions data.
Policy Trade-offs and Stakeholder Impacts The proposed extension balances climate ambition with economic competitiveness. EU downstream industries (e.g., machinery, automotive) will face higher compliance costs and administrative burdens from new reporting and traceability requirements, but will benefit from reduced carbon leakage risk as imported goods face equivalent carbon costs. EU producers of steel and aluminium may see improved competitiveness as downstream importers face higher costs. Third-country exporters, especially from developing nations, will encounter expanded CBAM obligations, potentially increasing trade friction, though the Commission notes limited impact on LDCs. EU customs and regulatory authorities will need to manage a significantly larger product scope and enhanced enforcement mechanisms, requiring additional resources and coordination.
Next Steps in Legislative Procedure The detailed proposal, supported by an impact assessment and public consultation, formally launches the co-decision process. The Council will now examine the proposed extension's scope, administrative burden, and economic impacts, potentially leading to debates over the product list and support for affected sectors. The European Parliament will also begin its scrutiny, with negotiations expected to focus on the 'balanced extension' (Option 2) presented as the preferred approach. The outcome will shape the EU's climate policy framework and its use of trade measures to incentivise global decarbonisation.
