MintCarb verification is not just a workflow — it is a structured, evidence-backed process aligned to ISO 14064-3 and ISAE 3000 that produces certificates no regulator, registry, or counterparty can reject.
Most carbon verification happens offline — email trails, PDF attachments, spreadsheet checklists, and manually typed statements. MintCarb replaces all of it with a digital-first, evidence-anchored workflow that produces globally unrejectable certificates.
Verifiers operate in a completely separate workspace from the entities they audit. Data access is scoped, time-limited, and logged. No conflict of interest is architecturally possible — it is not a policy, it is a system constraint.
Every reported number links directly to the source documents behind it — energy bills, meter readings, fuel receipts, process logs. Verifiers do not chase evidence; it is already there when the audit begins.
Every certificate carries a certificate ID, the evidence trail, the methodology, the NCR log, and the verifier's digital signature — aligned to ISO 14064-3, ISAE 3000, and ISSA 5000. Accepted by CCTS, CCS, CBAM, and all major registries.
Every verification follows a structured, auditable sequence. Nothing is informal. Every step creates a permanent, reviewable record.
The Lead Verifier defines the scope — reporting boundary, reporting period, applicable standard, and assurance level. The entity's data and evidence are formally handed over for audit.
Verifiers work through a structured evidence library. Source documents — bills, meter logs, production records — are reviewed against reported figures. Every review action is time-stamped and attributed.
Non-conformance requests are raised directly against specific data points, with deadlines and owners assigned. Resolution is tracked inside the platform. The NCR log becomes part of the permanent audit record.
Once all NCRs are closed and checklists complete, the Lead Verifier generates and digitally signs the verification statement. The certificate carries a unique ID, the full evidence reference, and the applicable standard — ready for submission to any regulator or registry.
The international standard for third-party verification and validation of greenhouse gas statements. MintCarb's verification workflow is structured around ISO 14064-3 requirements — materiality thresholds, sampling methodology, evidence standards, and assurance levels (limited and reasonable).
✓ Fully AlignedThe IAASB standard for assurance engagements on non-financial information — the framework that governs most regulated carbon verification globally. MintCarb certificates satisfy ISAE 3000 engagement requirements for both limited and reasonable assurance.
✓ Fully AlignedThe IAASB's new sustainability assurance standard, effective 2026 — covering ESG and climate disclosures including BRSR, TCFD, and GRI. MintCarb's verification engine is designed for ISSA 5000 compliance from the start, not retrofitted.
✓ ReadyIf you need third-party verification to comply with CCTS, CCS, CBAM, or to support BRSR/GRI disclosures — MintCarb gives your verifier a structured digital workspace with all the evidence they need already organised. No more emailing spreadsheets. No more chasing documents. The audit starts from a clean, complete data room.
Your verified certificate is issued with a unique ID, a full evidence reference, and the verifier's digital signature — ready for submission to any regulator, registry, or counterparty on the same day the audit concludes.
MintCarb gives accredited verifiers a purpose-built digital workspace — not a generic document management system adapted for carbon. Evidence library, NCR management, site visit logs, checklist completion, independence confirmation, and statement generation are all in one place, all linked to the data they relate to.
Every verification engagement produces a complete, tamper-evident audit trail that satisfies ISO 14064-3, ISAE 3000, and ISSA 5000 — and stands up to any accreditation body review.
Structured document management for all source records — energy bills, meter readings, fuel logs, process records, third-party invoices. Tagged by scope, site, period, and standard with full version history.
Raise, assign, track, and close non-conformance requests against specific data points or evidence gaps. Every NCR carries a deadline, owner, and resolution trail that satisfies any accreditation body.
ISO 14064-3 and ISAE 3000 aligned verification checklists built into the workflow. Every completed item is recorded with who reviewed it, when, and against which evidence — permanently.
Formal records of site visits with attendees, observations, findings, and photographs. Integrated with the evidence library so site observations link directly to the data they support or challenge.
Verifiers confirm independence from the entity at engagement start. Conflict of interest declarations are recorded and stored as part of the engagement record — satisfying every professional standard.
Digitally signed verification statements with a unique certificate ID (MCV-26-XXX format), full evidence cross-reference, NCR summary, and applicable standard. Issued in minutes, valid globally.
