Validation and Verification Bodies or Designated Operational Entities

Validation and Verification Bodies or Designated Operational Entities (CDM/PACM) are critical third-party auditors in carbon markets — they ensure the credibility, accuracy, and integrity of emissions reductions/removals claimed by projects before credits are issued.

Estimated project volume as proxy for
VVB Demand in 2025 & Beyond

Between 10,000 - 13,000 distinct project engagements
(validations or verifications) annually.
Ranges reflect the share of pipeline that actually advances to validation in 2026–2028 and the frequency of verifications per active project

requirements

What it takes to become a
 VVB or DOE?

  • ISO Accreditation: Valid GHG conformity accreditation (e.g., ISO 14065/ISO 14064-3) from an International Accreditation Forum  member .
  • Quality Management System: Documented, implemented, and auditable procedures governing VVB/DOE activities, consistent with programme requirements (often mapped to ISO/IAF expectations).
  • Auditor Competence: Team members must demonstrate relevant technical qualifications, training, and experience in GHG validation/verification aligned with standards’ competency frameworks (e.g., ISO 14064-3, CCMA, programme-specific exam requirements for Gold Standard).
  • Impartiality & Conflict-of-Interest Safeguards: Policies and procedures to ensure independence from project developers and avoidance of self-review/consultancy conflicts.
  • Professional Liability Insurance: Typically required to underwrite validation and verification work.
  • Accreditation and annual maintenance fees: Typically range from about USD 5,000–15,000 for initial accreditation, USD 3,000–10,000 for reaccreditation, and USD 2,000–8,000 per year for annual fees, depending on scope and programs.
