CBAM mirrors EU ETS free allocation — certificates are owed only on emissions above your CN code's benchmark, phased down year by year. Check the live status here.
Per Directive 2003/87/EC Art.10a(1a), the EU ETS free allocation covering CBAM sectors decreases over time — from 97.5% in 2026 down to 0% by 2034. This phase-down scales the benchmark credit, not your whole obligation.
