Tracker · ICVCM Core Carbon Principles

ICVCM CCP tracker

The Integrity Council for the Voluntary Carbon Market (ICVCM) assesses carbon crediting methodologies against its Core Carbon Principles (CCP). This page mirrors its public assessment-status table (last fetched 2026-10-04) and joins each methodology with the number of projects CarbonMeld tracks under that registry methodology code. A CCP label applies to credits issued under the approved methodology versions; "under assessment" means the ICVCM has published no decision yet.

  • 48 CCP-Approved
  • 22 Does not meet
  • 2 Remedial Action
  • 112 Under assessment
