Validation & Verification
Under the VCS Program, auditors known as validation/verification bodies (VVBs) are tasked with assessing projects against the VCS Program rules and the requirements of the applied methodology. VVBs are qualified, independent third parties which are approved by VCS to perform validation and verification. This independent assessment process is critical to ensuring the integrity of the projects registered with the VCS Program.
Currently, more than twenty VVBs located across five continents are approved under the VCS Program. VVBs are accredited to work in specific sectoral scopes, meaning their expertise is geared directly toward the types of projects they audit.
VVBs are eligible to provide validation and verification services under the VCS Program if they have signed the required agreement with VCS and are accredited by a VCS-recognized accreditation body.
