What are the requirements for VVBs that have previously performed validation or verification activity for a project?

If the same VVB wishes to perform verification of a given project activity for which they have performed validation (including the inclusion of Voluntary Project Activity (VPA)/Component Project Activity (CPA), renewal of crediting period, design change review), the VVB shall ensure that the integrity and impartiality of the verification audit are maintained. In such cases, the VVB shall meet the following requirements:

• The VVB shall ensure that the entire verification audit team, including the lead auditors, auditors and sectoral experts, are different from the team that performed the validation activity (including the inclusion of VPA/CPA, renewal of crediting period, design change review).

• The VVB shall transparently disclose in the verification report that the same VVB has performed validation activity (including the inclusion of VPA/CPA, renewal of crediting period, design change review) for the given project. The VVB shall disclose the details of the audit team, including names of all the team members and their roles in the previous audit performed by the same VVB.
