Information on Validation and Verification


The validation process is to ensure that the on-ground implementation of the project is reflective of the PDD and adheres to the Plan Vivo Standard. For more information on validation, please read these read the Project Validation Guidance documentation.


Verifiers assess a project's continued performance against the Plan Vivo Standard and achievement of expected emissions reductions. Verification is required within 5 years  of project registration and at least every 5 years thereafter. Verifiers are chosen by projects but must be approved by the Plan Vivo Foundation.

Approval of Verifiers and Validators

The Plan Vivo Foundation will approve verifiers and validators who:

  • Have appropriate experience and expertise in community-based Payments for Ecosystem Service projects;
  • Have documented experience in verifying GHG reductions and using sustainability metrics;
  • Are accredited by an appropriate authority such as the CDM, ISO 14065, FSC (not applicable for local validators)

Any prospective Validation & Verificaiton Body (VVB) may contact Plan Vivo and request a VVB application form.

Approved Validation & Verification Bodies

Under the Plan Vivo system, projects are independently validated by third party experts before a project is registered.

Verifications of registered Plan Vivo projects should take place at least every 5 years, in accordance with requirements outlined in the Plan Vivo Standard. The purpose of project verification is to ensure periodic, thorough, independent assessments of project design and implementation against the Plan Vivo Standard. Through these assessments, approved Validation and Verification Bodies (VVBs) confirm that project activities are described as stated in PDDs, that project partners have sufficient capacity to implement the project's objectives successfully, and that the ecosystem service benefits, e.g. emissions reductions, are being achieved as envisaged. Where a project is not meeting any particular requirement(s) under the Standard, corrective actions (CARs) with defined timescales will be imposed and progress against these monitored.

Cost and fees of verification will vary based on project size, scope and many other variables. It is recommended to start planning for verifications several months (6 months is advised) in advance of the desired verification visit. Projects may also contact the Foundation to request approval of additional VVBs, which will be assessed on an individual basis by the Technical Advisory Committee.

The Plan Vivo Foundation currently authorises the following organisations to conduct project verifications:
