Replace ad-hoc spreadsheets with a structured, regulation-aligned platform for quarterly CBAM report preparation, embedded emissions documentation, and audit-ready output.
Under EU Regulation 2023/956, EU importers of covered goods must submit quarterly CBAM reports documenting the embedded carbon emissions of their imports. This is a legal obligation — not an optional ESG disclosure.
CBAM reports must be filed quarterly via the EU CBAM Registry. Each report covers import declarations for the relevant quarter and must include emissions data for each good and installation.
Reports must document the actual embedded carbon emissions of imported goods — direct and, where applicable, indirect — sourced from non-EU production facilities. Default values may apply in some cases but carry regulatory risk.
Each emissions figure must be supported by traceable source documentation: supplier declarations, production data, methodology notes, and calculation evidence — all structured for potential audit.
Every imported product must be classified under the correct CN code within CBAM scope. Incorrect classification can lead to reporting gaps or penalties — a structured software workflow reduces this risk.
CBAM requires emissions data at the level of individual production installations — not just at the product or supplier level. Managing this granularity across multiple suppliers is one of the key operational challenges.
CBAM declarations may be reviewed by national competent authorities. Reports without adequate supporting documentation — or based on unsubstantiated estimates — carry regulatory and financial risk.
Many compliance teams start with spreadsheets. As supplier count grows and reporting requirements tighten, the limitations become costly compliance risks.
| Reporting Challenge | Spreadsheet approach | CBAM HUB |
|---|---|---|
| Data collection from multiple suppliers | Ad-hoc emails, inconsistent formats | ✓ Structured templates, repeatable process |
| Emissions calculation methodology | Manual formulas, version confusion | ✓ Regulation-aligned calculation logic built in |
| Supporting documentation | Files scattered across email and drives | ✓ Centralised evidence files per data point |
| Data completeness tracking | Manual status cells, easy to miss gaps | ✓ Completeness indicators per supplier/category |
| Audit trail | Difficult to reconstruct change history | ✓ Structured audit trail for all inputs |
| Multi-user collaboration | Version conflicts, overwrite risk | ✓ Role-based access, team workflows |
| Report output format | Manual XML construction, high error risk | ✓ Structured output supporting XML generation |
CBAM HUB structures your reporting workflow around the actual steps required by the regulation — from supplier data collection through to quarterly submission preparation.
Define your CBAM-covered imports by CN code, country of origin, and supplier installation. This forms the structured foundation for your quarterly reporting scope — ensuring no covered goods are overlooked.
Use structured data collection templates to gather installation-level emissions data from each non-EU supplier. CBAM HUB tracks completeness per supplier and flags outstanding responses before your reporting deadline.
Embedded emissions are calculated using methodology aligned with the CBAM Implementing Regulation — covering both direct and indirect emissions where applicable, with documented calculation notes for each figure.
Attach supplier declarations, production data, test reports, and other evidence directly to the relevant data records. All documentation is linked to the emissions figures it supports — creating a traceable, auditable structure.
Produce a structured documentation package — including data summaries, methodology notes, and the structured data inputs needed for CBAM XML report generation — ready for quarterly submission preparation and internal or external review.
CBAM compliance involves multiple functions. CBAM HUB is built for the teams who own the data, the process, and the regulatory exposure.
Compliance managers who need a structured, defensible process for quarterly CBAM reporting — not a spreadsheet that could be challenged in an audit. CBAM HUB provides the workflow structure and documentation trail that compliance functions require.
Customs teams managing CN code classification, import declarations, and supplier relationships are often closest to the raw data CBAM requires. CBAM HUB connects that data to the reporting workflow — reducing duplication and errors.
ESG functions increasingly own CBAM data as part of broader carbon accounting. CBAM HUB provides a structured methodology for embedded emissions documentation that can feed both CBAM reports and wider sustainability reporting.
Finance teams need to understand CBAM certificate costs and financial exposure. CBAM HUB's structured data provides the emissions figures needed to model CBAM cost implications — grounded in documented, auditable inputs.
