The third pillar of the professionalism and credibility of the CSG STANDARD is the verification by an external, independent third-party. Every CSG STANDARD project has to undergo a verification process by an independent certification body in order become realized. The task of the certification body is to approve the project plans, and monitor the emissions reductions achieved.
The external certification body operates completely independently from the CSG STANDARD and provides continuous information about the verification results. Only projects that have been approved by the verification body and the TAP (including: complete documentation reviews and a review of the monitoring system) — are allowed to issue credits. CSG uses the observations of independent auditing verifiers to further improve its methodologies.
