CBAM (Carbon Border Adjustment Mechanism) – what is it?
EU mechanism to prevent carbon leakage by applying CO₂ pricing to imports of carbon-intensive goods, with the following timeline:
Transition phase incl. Omnibus simplifications (2023-2025)
-
Reporting obligations in force since October 2023; quarterly reports on imports, emissions, and CO₂ prices that are due in a third country.
-
Fines for non-compliance; de-minimis threshold exempts imports ≤50 tons/year.
Definitive period (starting January 2026)
-
Only approved CBAM declarants may import CBAM goods (if de-minimis rule is not applicable).
-
Annual declarations due by September 30, of the following year; independent third-party validation of declared values required.
Adjustments and expansion (2027–2030)
-
Certificate purchase for 2026 CBAM imports starts February 2027.
-
CBAM scope may expand to chemicals/polymers by 2030; free allowances under EU Emission Trading System (ETS) phase out by 2034.
Why act now?
Authorized CBAM declarant: status mandatory from 2026 for importation
-
Registration open since March 2025 via the EU's Authorization Management Module (AMM).
-
Requires i.a., EORI number, portal access, supporting docs; approval may take up to 180 days.
-
Failure to register will block imports of covered goods starting January 2026.
Consider costs for certificates in financial planning as they will impact EBITDA
-
Companies must budget for CBAM certificates in 2026, even though the issuance begins in February 2027 (retroactive for imports from January 2026).
-
CO₂ taxes or carbon pricing mechanisms paid in the country of origin can be deducted from liabilities under CBAM regulation.
Sanctions and Compliance Risks
-
Up to €100 per undeclared ton of CO₂ for non-compliance.
-
Repeated breaches may result in the loss of CBAM declarant status, effectively halting imports.
-
Companies must ensure accurate reporting and timely submission of CBAM declarations to avoid penalties.
