Grounds for refusal

Either VVB does not approve; the methodology doesn’t comply with the Carbon Standard or the Validation and Verification Standard; its quality is below NCCF’s benchmarks; or it conflicts with the Registry’s philosophy or integrity.

Fees are not refunded on rejection. Methodology fees are on Methodology fees and compensation.
