The European Commission publishes the first official CBAM certificate auction price. Q1 2026: €75.36/tCO2, the reference price for modelling.
The Commission begins negotiations with Turkey, Serbia, Bosnia, and North Macedonia on cement-specific defaults, with parallel discussion on Vietnam, India, and UAE.
Hard legal deadline under Regulation (EU) 2023/956. The Commission must publish country-specific cement defaults for at least 5–7 countries.
New country-specific cement defaults published in December 2027 become effective. A mark-up schedule applies: +20% on defaults.
