Does Carbon Mandate verify, or sign the assurance opinion?

No. Carbon Mandate runs the pre-verification screening — it ingests data, screens it against the CBAM methodology, and surfaces findings. The accredited verifier determines materiality, issues the assurance opinion, and signs the report. Independence is untouched.

What accreditation governs CBAM verifiers?

Accredited CBAM verifiers are accredited against EN ISO/IEC 17029:2019 by an EU national accreditation body, building on the EU ETS accreditation framework — Implementing Regulation (EU) 2018/2067 — and its Annex I activity groups. See Delegated Regulation (EU) 2025/2551.

What assurance level does CBAM verification require?

Reasonable assurance. The verifier must reduce verification risk to an acceptable level to obtain reasonable assurance that the emissions report is free from material misstatement. See Implementing Regulation (EU) 2025/2546, Article 3.

Is a physical site visit mandatory?

Yes. A physical visit to the installation is required in the first verification year and cannot be waived. From 2027 a visit may be replaced or waived only under the narrow low-risk conditions in the verification rules, with a physical visit at least once every two reporting periods. See Implementing Regulation (EU) 2025/2546, Recital 3 and Article 3.

What does the accredited team receive?

A schema-checked dataset and a 47-rule findings report — flagged anomalies, data gaps, and default-vs-actual divergence, each cited to its source field. Structured inputs your team acts on, not a PDF to interpret.

ACCESS

Annual access, priced per installation volume

Verifier access is quote-led — banded by the number of CBAM installations you verify each year. No public price; request a figure for your volume.

VERIFIER

XML conformance for CBAM verifiers

You are the accredited verifier. Carbon Mandate tells you in seconds whether the CBAM file in front of you is schema-valid XML — or a template that isn't. It checks the file's structure against the CBAM XSD. It does not form the verification opinion. That stays with you.

HOW IT WORKS

Three moves from raw data to a scoped engagement

Carbon Mandate runs the pre-verification screening. Your accredited team determines materiality, issues the assurance opinion, and signs the report.
