The CBAM Definitive Phase: Between Regulatory Ambition And Political Hesitation

Designed as a cornerstone of the EU's climate strategy, the Carbon Border Adjustment Mechanism ("CBAM") aims to prevent carbon leakage by ensuring that imported goods (cement, iron and steel, aluminum, fertilizers, electricity, and hydrogen) are subject to carbon costs equivalent to those faced by European producers. In theory, the mechanism reinforces climate ambition while preserving industrial competitiveness. In practice, its final implementation has been accompanied by growing uncertainty. 

After a transitional period focused on reporting and data collection, the definitive phase, launched on January 1, 2026, introduces concrete financial obligations for importers of carbon-intensive goods. This shift marks a qualitative change: CBAM moves from a monitoring tool to a fully-fledged economic instrument.
