Third-Party Verification
Third-party verification is the independent assessment of an organisation’s greenhouse gas data by a qualified external verifier, providing assurance to stakeholders that the reported emissions are accurate and complete.
What is Third-Party Verification?
Third-party verification involves an independent assessor reviewing data collection processes, calculation methodologies, emission factor selection, and reported figures against a standard (typically ISO 14064-3 or ISAE 3410). Verifiers may be accredited certification bodies (UKAS-accredited in the UK) or qualified assurance providers. Verification can be at limited or reasonable assurance level.
Practical Examples
A company engages a UKAS-accredited verifier to provide ISO 14064-3 limited assurance over its Scope 1 and 2 inventory.
A company seeking SBTi target validation ensures its base year emissions are independently verified before submission.
