CBAM verification: prepare installation evidence before engaging a verifier
The acquired August 2026 Commission-services guidance explains verification of installation emissions reports for the definitive period. It separates preparation of monitoring and production data, the verifier’s engagement assessment and the report handoff. Published default values are reference data; they do not become measured supplier emissions or a complete certificate-liability calculation.

What belongs inside the evidence boundary?
The guidance describes monitoring-plan conformity and completeness of the reporting period, production processes, goods, source streams, precursors and relevant emissions data. [2]
Map the actual installation/processes and reporting period; reconcile source records and identify missing precursor or measurement evidence.
Can this verifier undertake the actual engagement?
The pre-contract discussion addresses installation-specific risks, impartiality, planning and the ability to work in the installation’s country. [3][4]
Ask for current relevant accreditation evidence and an installation-specific engagement assessment, including language, site access and independence.
Which resources and scope are included in the quotation?
The guidance describes assessment of supplied information and the competence, personnel and resources for the specific installation and production processes. [4]
Agree scope, evidence access, responsible team, unresolved data and deliverables before accepting a generic verification quotation.
How will the verified report reach the operator and declarant?
The report-transmission discussion distinguishes operators registered in the CBAM Registry from the export/transmission route for operators not registered there. [5]
Confirm the actual registration/access context and the signed-report handoff; keep full operator data and the shared verified summary appropriately separated.
The guidance expressly is nonbinding and explanatory; authentic Union acts govern. Commodity classification, installation facts, accreditation currency, actual-emissions eligibility, exemptions and certificate liability require separate current assessment. No provider accreditation is inferred from a Cruxi listing.
