Validation & Verification Bodies

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.

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

If you are interested in becoming a Gold Standard approved VVB, go to the VVB page.

The VVB is in the process of re-approval. This means

  • Projects submitted for design certification and performance certification by December 31, 2021, shall be reviewed by SustainCERT as usual. 
  • Validation and verification services contracted before December 31, 2021, can be performed as usual. 
  • However, should the validation/verification report be submitted after December 31, 2021,  the design/performance certification may only commence after the VVB’s re-approval is confirmed by Gold Standard.
