Response to EU CBAM Q4 2025 Legislative Proposal

  • The December 2025 legislative package engages with several longstanding design questions as the CBAM enters its definitive phase, including, among other topics, anti-circumvention, downstream scope extension, the treatment of third-country carbon prices, export-related leakage, and introducing a new safeguard mechanism under Article 27a.
  • The proposals represent an important step in the operationalization of the CBAM and an effort to make it fit for purpose, but multiple elements show unresolved trade-offs between environmental ambition, administrative feasibility, and regulatory predictability.
  • The credibility and effectiveness of the mechanism will depend heavily on how the forthcoming implementing acts and the upcoming ETS revision address the remaining gaps.
