CBAM Certificate Cost & Free-Allocation Engine

Converts embedded emissions into a CBAM certificate liability: applies the CBAM factor (free-allocation phase-out 2.5% in 2026 rising to 100% in 2034), deducts any carbon price already paid in the country of origin, prices certificates against the EUA reference, and projects the quarterly holding and surrender schedule. Part of the cbam-liability chain.

CBAM factor 2.5% (2026) → 100% (2034) Surrender deadline 30 Sep each year Verify EUA price source
