Validation

Validation is an empanelled VVB’s independent evaluation of a project’s design against the Carbon Standard. It is required before registration and results in a Validation Report (VaR).

Appointing the VVB

Appoint a VVB that is empanelled with CR-I in the relevant sectoral scopes, and accredited in all scopes covered by the methodologies used, under a legal contract. Micro-scale projects may use an IVVE. See the list of empanelled VVBs.

What the VVB checks

  • Use of the current DPD template and the Delegate Entity’s appointment
  • Project ownership and its evidence
  • Project description, external project status and, for AFOLU, the Minimum Buffer Percentage
  • Scale and boundary, against site observations
  • Local stakeholder consultation and the SCR
  • Start date and crediting period
  • Application of the methodology, deviations and the baseline
  • Additionality and emission estimates
  • Monitoring approach, safeguards and SDG contribution

How it works

The VVB agrees the objectives, scope, criteria, level of assurance and materiality with the IPP first. It uses desk review, a site visit and follow-up. It must reach at least reasonable assurance, raises findings where needed (see Findings), and addresses the comments from public consultation and NCCF.

The result

A Validation Report (VaR) on the CR-I template, with a validation statement. The VVB then submits the request for registration.
