Approved auditors

Monitoring, reporting, and verification (MRV) are essential elements of climate and development initiatives, ensuring that project investments go further to deliver greater impacts – a key outcome from Gold Standard programmes. 

Validation/Verification Bodies (VVBs) play an important role in this MRV process, conducting third-party assessments to provide independent confirmation that projects are in line with Gold Standard Requirements.

The table below provides the list of accredited VVBs and the eligible auditors within their organisations. Project Developers can choose from any of the following VVBs for Gold Standard certification based on the project type and certification pathway. The list will be updated continuously to reflect the most recent status of the applications.


Gold Standard acknowledges a backlog of VVB applications, therefore, hereby clarifies that VVBs may continue to perform validation and verification services even after expiry of Gold Standard Validation/Verification Body Approval as long as: 

  • They have applied for approval before 30 September 2021 (as indicated with an * on the Approved Auditors list)
  • Any new contracts for validation/verification services are signed before 31 December 2021
  • The Validation and Verification reports are submitted before 31 December 2021 to be considered valid for design/performance certification

For contact details of the GS-VVBs below, you can refer to their listing on the UNFCCC CDM website.
