CBAM 101: from transitional reporting to settlement
A practical prep plan for data, governance, and certificate budgeting.
The Carbon Border Adjustment Mechanism (CBAM) shifts from quarterly reporting to financial settlement in 2026. Importers must purchase certificates, evidence embedded emissions and explain variances. This primer moves you from awareness to concrete actions.
1. Scope and product inventory
- HS codes in scope: steel, aluminium, cement, fertilisers, electricity and hydrogen.
- Organise by supply chain: map suppliers, plants and production processes per product group.
- Gather contract data: prices, volumes, INCOTERMS and clauses covering emission disclosures.
2. Data capture and quality
- Primary data. Request verified embedded emissions (tCO2e per tonne) with methodology statements.
- Fallbacks. Document when default values or EU benchmarks are applied.
- Lineage. Link every data point to a batch, production period and supplier.
3. Certificate budgeting
- Scenarios. Model high/mid/low price paths based on policy shifts and market volatility.
- Buffer. Account for certificates that expire or cannot be sourced in time.
- Cash flow. Plan for quarterly settlements and potential guarantees.
4. Governance and roles
| Function | Responsibilities |
|---|---|
| Sustainability | Collect emission data, coach suppliers |
| Finance | Budget certificates, manage cash flow |
| Compliance | Maintain audit trails, monitor regulatory updates |
| IT/Data | Manage integrations, dashboards and workflow automation |
5. Reporting and audit trail
- Quarterly dossiers. Combine emissions, volumes, certificates and corrections.
- Explainability. Document why defaults were used and which controls ran.
- Audits. Prepare sample packs showing the trace from import invoice to emission source.
6. Connect with PSRA workflows
PSRA unifies CBAM reporting with preferential origin (RoO), LTSD and supplier compliance. One dossier per product removes duplication and delivers consistent narratives during audits.
