Validation and Verification Manual (VVM)

The Validation and Verification Manual is a standard designed to assist DOEs with their validation and verification work. It was adopted by Executive Board at its 44th meeting and outlines requirements for validation and verification reports. The aim of the Manual is to promote quality and consistency in DOE reports and ensure each project activity meets all applicable CDM requirements.

DOEs are required to apply the principles of consistency, transparency, impartiality and confidentiality when preparing validation and verification reports.

Principles for validation and verification

  1. DOEs shall apply the following principles in performing validation and verification and in preparing validation and verification reports.
  1. Consistency
  1. Consistency is achieved by:
    1. Applying uniform criteria to the requirements of the applicable approved methodology throughout the crediting period(s);
    2. Applying uniform criteria among project activities with similar characteristics such as a similar application of the approved methodology, use of technology, time period or region;
    3. Applying uniform criteria to expert judgements, over time and among projects.
  2. The principle of consistency shall not prevent a DOE from applying the most recent decisions and guidance provided by the CDM Executive Board.
  1. Transparency
  1. Information in the validation and verification reports shall be presented in an open, clear, factual, neutral and coherent manner based on documentary evidence.
  2. Transparency requires DOEs to:
    1. Clearly and explicitly state and document all assumptions;
    2. Clearly reference background material;
    3. Clearly identify changes made to documentation.
  1. Impartiality, independence and safeguarding against conflicts of interest
  1. DOEs shall remain independent of the project activity being validated or verified. They shall also remain free from bias and any real or potential conflict of interest.
  2. Appendix A to the CDM modalities and procedures specifies that DOEs shall work in a credible, independent, non-discriminatory and transparent manner. The structure of the DOE shall safeguard the impartiality of its operations. If the DOE is part of a larger organization, the DOE shall clearly define the links with other parts of the organization to demonstrate that no conflicts of interest exist. DOEs shall
    remain free of any commercial, financial or other processes that influence its judgement or endanger trust in its independence and integrity.
  3. DOEs shall base their findings and conclusions upon objective evidence and shall conduct all activities in connection with the validation and verification processes in accordance with the rules and procedures of the COP/MOP and the CDM Executive Board.
  4. In their reports, DOEs shall truthfully and accurately state their validation or verification activities, findings and conclusions.
  1. Confidentiality
  1. In accordance with the CDM requirements, DOEs shall safeguard the confidentiality of all information obtained or created during validation or verification (EB 55, Annex 1, paragraphs 14-23).

If the Executive Board requires clarification, the DOE must provide a response and any additional information requested. This also applies to reviews of project activities associated with validation or verification.

In response to reviews of project activities associated with validation or verification requirements and requests for clarification from the CDM Executive Board, DOEs shall provide a response and where possible the additional information requested (EB 55, Annex 1, paragraph 25).
