Overview
Validation and verification are critical to ensuring the integrity and quality of the projects registered in Verra’s programs and program methodologies. These processes are conducted by validation/verification bodies (VVBs)–qualified, independent third-party auditors who are approved by Verra. VVBs are experts in the program and sectoral scope or technical area they audit.
During validation, a VVB determines whether a project meets all rules and requirements from the Verra programs. Once validation has been concluded, the project proponent may submit the project for registration with the respective program.
During verification, a VVB confirms that the outcomes set out in the project documentation have been achieved and quantified according to the requirements of the respective standard.
Accreditation
Each Verra program has specific rules and requirements that VVBs must meet before becoming active auditors and that are set out in the respective program section.
Suspension or Loss of Accreditation
A VVB becomes inactive when their accreditation is terminated or when they are suspended by the body under which they are accredited, or if Verra suspends or terminates its agreement with the VVB.
Verra doesn’t permit inactive or suspended VVBs to conduct any validation and verification audits or issue validation and verification reports until Verra reinstates their eligibility.
VVB PERFORMANCE MONITORING PROGRAM (PMP)
Verra’s VVB Performance Monitoring Program (PMP) is fundamental to Verra’s comprehensive oversight of VVB performance. The PMP enables Verra to monitor and strengthen VVB performance across all Verra standards programs.
SUPPORTING VVBS
As the rules of Verra’s programs continue to evolve, Verra is committed to supporting VVBs through clear, transparent, and consistent guidance so that they can conduct high-quality audits. Verra provides VVBs with regular trainings to share program updates, clarifications and create a space for discussion. In addition, to foster continuous improvement of individual VVBs as well as Verra’s system as a whole, Verra provides direct performance feedback to VVBs, considers rule clarification requests, and offers opportunities for dialogue on quality, consistency, and performance expectations. Together, these efforts maintain the integrity of the validation and verification process, while also upholding VVBs’ independence.
VVB Sanctions
Based on its validation/verification bodies oversight activities, Verra has sole discretion to apply sanctions to VVBs if it identifies non-conformances or other performance issues. For example, VVBs may be found to conduct services not in conformance with the governing accreditation body and/or VCS Program rules, or Verra identifies systemic or repeated deficiencies, such as recurring non‑conformances or failure to implement required corrective actions. These sanctions against VVBs will vary depending on the severity of issues and/or non-conformance(s) and may include the following:
- Issuance of a warning.
- Referral of non-conformity reports and PMP results to the relevant accreditation body.
- Suspension
- Termination
VVB sanctions are described in detail in section 6 of the VCS Program Guide (see the VCS Program Details – Verra VCS Rules and Requirements page for the most recent version).
For the VCS Program
During validation and verification, VVBs rigorously evaluate projects against the VCS Program rules and the applied methodologies.
VVBs may be located anywhere in the world and are eligible to provide validation and verification services under the VCS Program if they are accredited by a VCS-recognized accreditation body, have received Verra authorization, have signed the required agreement with Verra, and paid the annual validation/verification body fee.
Qualified validation/verification bodies (VVBs) also perform rigorous assessments of VCS methodologies and methodology elements to confirm that they conform with VCS Program requirements and sector-specific best practices. The contracted VVB must meet the eligibility criteria set out in the VCS Program Guide (see the VCS Rules and Requirements page for the most recent version). and must hold accreditation or approval for validation or verification (as applicable) for the sectoral scope(s) applicable to the respective methodology project. Where the methodology falls under more than one sectoral scope, the VVB body shall hold accreditation or approval for validation or verification (as applicable) for all relevant sectoral scopes.
The below overview of VCS and ANAB sectoral scopes informs for which VCS sectoral scopes ANAB-accredited VVBs can provide validation or verification.
Projects, activities, or methodologies can be developed under any of the 16 VCS sectoral scopes.

* Sectoral scope applies to two ANAB groups
The growth of the voluntary carbon market has fueled demand for new validation/verification bodies (VVBs). VVBs may be located anywhere in the world. They must have accreditation by an International Accreditation Forum (IAF) Multilateral Recognition Arrangement (MLA)- recognized accreditation body for ISO 14065 scope VCS. IAF MLA (external) accreditation bodies with such programs currently include the following:
- ANSI National Accreditation Board (ANAB)+
- Egyptian Accreditation Council
- Entidad Mexicana de Acreditación (EMA)
- Global Accreditation Bureau (GAB)
- National Accreditation Board for Certification Bodies (NABCB)
- Organismo Nacional de Acreditación de Colombia (ONAC)
- Sri Lanka Accreditation Board for Conformity Assessment (SLAB)
- Standards Council of Canada (SCC)
- Taiwan Accreditation Foundation (TAF)
Some previously approved UNFCCC-accredited VVBs who are actively undergoing accreditation with an IAF MLA accreditation body as of 30 March 2023 may have been granted an extension to use their DOE accreditation until ISO 14065 scope VCS accreditation is received.
Once accreditation is achieved organizations are invited to complete and submit the VVB Application Form (DOC).
IAF MLA accreditation bodies are encouraged to develop accreditation programs for ISO 14065 scope VCS. Interested IAF MLA accreditation bodies should contact Verra directly.
Suspension or Loss of Accreditation
A VVB becomes inactive when its accreditation is terminated or suspended by the body under which it is accredited, or if the VCS suspends or terminates its agreement with the VVB. An inactive or suspended VVB cannot issue VCS validation or verification reports until the VCS reinstates its eligibility.
