View profile


Validation and verification, as conformity assessment activities, are a confirmation of the reliability of the information given in the declarations. Both activities are distinguished according to the time line of the evaluated claim. Validation applies to claims with respect to an intended future use or a projected outcome (confirmation of plausibility), while verification applies to claims with respect to events that have already occurred or results that have already been obtained (confirmation of veracity).

The accreditation scheme for validation and verification assesses the requirements for the competence, consistent operation and impartiality of validation and verification bodies to issue a decision as to whether a claim is in conformity (or not) with the initially specified requirements, where the body needs to gather information and develop a thorough understanding regarding compliance with those requirements. 


The accreditation scheme is aimed at validation and verification bodies for claims made by organizations in different sectors. 

Initially the scheme covers validation and verification for environmental claims under ISO 14065:2020 “General principles and requirements for bodies performing validation and verification of environmental information”, specifically for greenhouse gas claims, validation and verification are performed by bodies according to ISO 14064-3, in different industrial sectors.
