Approval of a new methodology
A new methodology goes from synopsis to full document, 30 days of public consultation, assessment by two independent VVBs and a final NCCF review before it is listed.

LCA-based methodologies, introduced in Carbon Standard v1.1, are not assessed by VVBs. See Which methodologies can be used?
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.
Withdrawing an approved methodology
The IMD can request withdrawal at any time, with reasons. NCCF reviews it within 14 working days after outstanding dues are cleared.
