Carbon Border Adjustment Mechanism
The Carbon Border Adjustment Mechanism (CBAM) is the EU's levy-on-imports that prices the carbon embedded in certain carbon-intensive goods at the EU Emissions Trading System (ETS) rate. Its aim is simple and systemic: prevent carbon leakage, reward cleaner production globally, and keep the single market fair as EU industry decarbonises.
A border adjustment that mirrors the EU ETS for imports. Importers of covered goods buy and surrender CBAM certificates priced off the weekly average EU ETS (€/tCO₂e), equal to the product's verified embedded emissions—minus any explicit carbon price paid in the country of origin.
Transitional phase (Oct 2023–Dec 2025):
reporting only, no payment. Sectors: cement, iron & steel, aluminium, fertilisers, electricity, hydrogen (incl. selected precursors and downstream items).
Definitive regime (from 1 Jan 2026):
only authorised CBAM declarants may import covered goods; annual surrender of certificates begins.
Free EU ETS allowances phase out in parallel;
CBAM phases in accordingly. Scope may widen by 2030 to additional ETS sectors.
Direct (Scope 1) process/fuel emissions from manufacturing the good. Indirect (electricity / Scope 2) for specified products (expanding by act). Where plant-level data are unavailable, default values can be used—but real, verified data typically lower the cost.
Register nationally and (from 2026) obtain authorised declarant status. Collect, calculate, and report embedded emissions per CN code each quarter during transition; annually from 2026 with verifier assurance. Purchase & surrender CBAM certificates equal to net embedded emissions (after crediting any paid carbon price abroad and EU free-allocation equivalence). Maintain auditable MRV (monitoring, reporting, verification) aligned to CBAM methods and the Commission's templates/registry.
Treat CBAM as an end-to-end data program, not just a customs step—product classification, supplier engagement, emissions accounting, verification, certificate management, and audit readiness all need to work as one.
Map covered CN codes and bill of materials for any CBAM precursors. Establish plant-level MRV that meets the CBAM methodology; secure supplier emissions for inputs that are themselves CBAM goods. Put data-sharing and audit clauses into contracts; protect trade secrets while enabling declarants' filings. Quantify any domestic carbon price paid (to be deducted at the EU border).Build digital traceability from mill/plant to shipment (batch, route, energy source, emission factors).
