VVB Performance Monitoring Program (PMP)

Verra assesses and closely monitors the level of competence of each individual VVB and identifies common issues by performing a range of oversight activities. These oversight activities can be grouped into the following four categories:

Verra uses the four oversight categories described above to monitor VVB performance. Based on a range of primarily quantitative indicators within each category, Verra captures the results of its assessments in individualized scorecards, which are issued to VVBs at least annually. While individual scorecards are not publicly available, Verra does publish high-level results from its performance monitoring program to support transparency and informed decision making.

The results from Verra’s VVB Performance Monitoring Program support Verra’s efforts to assess VVB performance and, based on these assessments, strengthen VVBs’ overall auditing capacity across all Verra programs. (For example, Verra may provide additional VVB trainings, review program rules and methodologies, increase and/or decrease VVB oversight activities, or apply sanctions where appropriate.) This, in turn, will ensure the integrity of Verra projects and the units issued.

Below is an overview of the 2025 public results from Verra’s VVB Performance Monitoring Program. These results are designed to support transparency and help stakeholders/project proponents make informed decisions by providing information on VVB performance across Verra programs.

Users are encouraged to use this information as a starting point as they consider potential VVBs for their project, but should also complement their research by consulting the full list of eligible VVBs and publicly available project data, and by engaging directly with VVBs to discuss relevant experience, qualifications, and project-specific factors (project location, project type, methodology applied).

Users can review performance monitoring results for VVBs by (a) methodology and (b) category (e.g., VCS NCS). Currently, these results are available only for the Verified Carbon Standard (VCS) and Climate, Community & Biodiversity Standards (CCBS) Programs.

Certain data points may be updated as Verra continues to review and incorporate feedback from VVBs. For questions or to provide feedback, please contact auditing@verra.org.

In this section, users can review VVBs’ performance when conducting audits of projects using a specific methodology.

Users can select a particular methodology to see a list of VVBs that have performed audits under this methodology in 2025 and a high-level overview of their performance (i.e., number of submissions, number of requests returned, percent of requests approved, average rounds of findings, and average number of findings during technical review rounds).

Note: If a particular VVB is not listed in the PMP results, Verra does not have any data about relevant project review requests closed during 2025.

To view a complete list of active VVBs, please visit the Validation and Verification page.

In this section, users can review VVBs’ performance when conducting audits of projects in a specific category (i.e., projects with broadly similar characteristics, such as land-based projects or energy and industry projects). This is useful when no methodology-specific PMP results are available for a particular VVB.

Because this information reflects performance across broader sectoral scopes, it offers a high-level summary of overall trends and should be interpreted as such. Users should bear in mind that the results shown here are also influenced by factors such as a small number of project submissions or new methodologies.

Within each category, benchmarks are calculated based on the aggregated results for each PMP indicator across all VVBs.

• A VVB’s performance is considered within benchmark when it meets the benchmark value.
• A VVB’s performance is considered above benchmark when it exceeds the benchmark value.

These classifications are designed to help users understand general performance trends.

VVBs whose performance fall below the benchmark are monitored by Verra as part of its ongoing oversight activities and are not listed here.

Please note, however, that VVBs are not listed here if Verra does not have any data about relevant project review requests closed during 2025.

All VVBs listed as active on the Validation and Verification page have been approved by Verra to conduct validation and/or verification activities.
