ISO 14064 GHG Verification Third-Party Assurance

ISO 14064 GHG accounting —
verification-ready inventory.

ISO 14064 is the international standard for greenhouse gas quantification, monitoring, reporting, and verification. Part 1 covers organisation-level GHG inventories. It specifies what must be documented, how emission factors must be cited, and what audit trail a verifier requires to provide independent assurance.

Sustaineve produces ISO 14064-1 compliant GHG inventories. Every emission figure includes its source data, IPCC emission factor with table reference, GWP value with AR5 citation, and calculation derivation — the exact documentation an ISO 14064-3 verifier requires to assess your inventory.

GHG Validation & Verification

Sustaineve's audit trail is structured to meet ISO 14064-3 verifier requirements. Third-party engagement is the organisation's responsibility.

What ISO 14064-3 verifiers require.

These are the documentation requirements that third-party verifiers check. Sustaineve builds them into every inventory.

ISO 14064 — common questions.

What is ISO 14064?

ISO 14064 is an international standard for GHG quantification, monitoring, reporting, and verification. Part 1 covers organisational inventories, Part 2 covers project-level reductions, and Part 3 specifies verification requirements. Together they provide a complete framework for credible GHG accounting and independent assurance.

What does ISO 14064-1 require?

ISO 14064-1 requires organisations to define their organisational and operational boundaries, identify all significant GHG sources, apply documented quantification methodologies with sourced emission factors, maintain records supporting verification, and report with transparency. Emission factors must reference recognised databases such as IPCC, with specific table citations documented.

How does Sustaineve support ISO 14064 verification?

Sustaineve produces documentation required for ISO 14064-1 third-party verification: source-level activity data, IPCC emission factors with table citations, full calculation derivations, GWP values with AR5 references, and an audit trail linking each tCO₂e to its source. Verifiers can trace every inventory figure to its original data and methodology.
