CBAM compliance software for embedded emissions

The CBAM transitional reporting period ended in 2025, and from 1 January 2026 the definitive regime applies: EU importers of cement, iron and steel, aluminium, fertilisers, electricity and hydrogen need authorised declarant status, annual declarations and CBAM certificates matching the embedded emissions of the goods they bring in. The buyers of compliance tooling are usually customs, procurement and finance teams that already have an import file, not sustainability departments starting from zero.

The hard part is data, not forms. Embedded emissions are calculated per installation and production route, split into direct and indirect emissions, mapped to CN codes and supported by evidence from an accredited verifier. Many non-EU suppliers cannot produce installation-level figures at all, so importers fall back to default values, which changes both the declaration and the certificate cost. Customs entries, supplier responses and the emissions file have to reconcile month by month, while the certificate price follows EU ETS auction prices.

Common failures are silent. A default value is used without being flagged, a CN code is mapped once and never reviewed, supplier data arrives after the declaration deadline, or the certificate quantity is calculated from a different emissions figure than the one declared. Each of these is cheap to prevent and expensive to correct after verification.

Assess tooling by whether it produces an auditable trail from customs line to installation to certificate, and whether that trail can be handed to a verifier without being rebuilt in spreadsheets.
