Voluntary Carbon Markets Integrity Initiative (VCMI)

The Voluntary Carbon Markets Integrity Initiative (VCMI) is an international initiative that guides the credible use of carbon credits by companies in voluntary carbon markets. Headquartered in London, United Kingdom, VCMI focuses on defining best practices for how organizations can make transparent and accountable climate claims when using carbon credits as part of their decarbonization strategies. Its Claims Code of Practice sets out requirements for emissions reductions, reporting, and the appropriate use of high-quality credits. VCMI works alongside standard setters, policymakers, and market participants to improve trust and integrity in voluntary carbon markets. By clarifying how carbon credits should be used and communicated, the initiative supports more effective and credible corporate climate action.
