VCMI is a multi-stakeholder platform to drive credible, net-zero aligned participation in voluntary carbon markets.

To avoid the catastrophic impacts of climate change, global warming must be kept to 1.5C above pre-industrial levels.

Voluntary carbon markets provide an opportunity to direct private finance towards climate mitigation and nature-based solutions.

But integrity is crucial. VCMI engages stakeholders around a shared mission to ensure voluntary carbon markets fulfil their potential to support the goals of the Paris Agreement.

VCMI connects and amplifies initiatives that share its vision for high integrity voluntary carbon markets. In addition, it focuses on a few key areas where there is a clear need for additional work.

Immediate priorities are to:

  • Develop high integrity guidance for buyers of carbon credits, including on climate claims by businesses.
  • Support access to high-integrity voluntary carbon markets and monitor broader supply-side integrity efforts.

Consultation Report

Consultation Report

VCMI’s Consultation Report has been developed with input from more than 300 stakeholders across the globe.

The report sets out:

  • An overview of the opportunity for voluntary carbon markets to make a meaningful and significant contribution to the Paris Agreement ambition to limit global warming to 1.5˚C above the pre-industrial era.
  • A vision and set of 10 principles to ensure voluntary carbon markets support high-integrity, Paris-aligned climate mitigation.
  • Key demand-side issues, and options for ensuring legitimate use of carbon credits and the validity of corporate net‐zero claims.
  • Key supply-side issues, and the opportunity to strengthen the capacity of countries to develop strategies that promote access to high integrity voluntary carbon markets.
  • The proposed role and governance of VCMI.

We are inviting feedback on the content of this report to inform the development of future VCMI guidance. Please share your views by 15th September 2021. Alternatively, you can share your views by downloading the feedback form and sending to

“Voluntary carbon markets can increase finance flows. I am pleased the UK Government is supporting the Voluntary Carbon Market Integrity Initiative to help ensure they deliver the greatest benefits for climate, for people and nature.”

“Without clarification — and real enforcement — net zero will become an empty slogan that governments, corporations and investors can use to greenwash emissions as usual.”

“Voluntary carbon market investment in natural climate solutions has the potential – only if it is done right – to accelerate climate mitigation while increasing much needed finance for natural climate solutions. Doing it right means respecting the rights, land, and territories of Indigenous Peoples; supporting projects governed by Indigenous Peoples and local communities while increasing finance for community conservations; and ensuring gender, social, and environmental standards.”
