Voluntary Carbon Markets 

Voluntary Carbon Markets (VCMs) enable organisations and individuals to finance climate action beyond regulatory requirements. Participants purchase carbon credits that represent one tonne of carbon dioxide equivalent (tCO₂e) reduced or removed from the atmosphere through verified climate projects. 

In a world that must rapidly decarbonise, VCMs provide a mechanism to channel finance to activities that reduce emissions today, particularly in regions and sectors where access to climate finance remains limited. 

The latest science underscores the urgency of action. The challenge is not only reducing emissions in line with the Paris Agreement, but also closing three critical gaps: 

• The emissions gap – between current trajectories and the temperature goals of the Paris Agreement. 
• The finance gap – where viable mitigation activities lack sufficient funding. 
• The time gap – where delayed action increases long-term climate and economic risks. 

VCMs can help address all three. 

Even with ambitious decarbonisation strategies, some emissions remain unavoidable in the near term. Financing high-impact emission reductions and removals beyond an organisation’s own footprint is one way to take responsibility for that impact while accelerating the global transition to net zero. 

When functioning with integrity, voluntary markets: 

• Direct private finance to mitigation activities that would otherwise struggle to secure funding 
• Support innovation in emerging mitigation and CO2 removal pathways 
• Deliver measurable climate benefits alongside social and environmental co-benefits 
• Enable earlier action while regulatory frameworks continue to evolve 

VCMs are not a substitute for deep internal decarbonisation. Rather, they are a complementary tool that supports broader system-wide transformation. 

Not all carbon credits are equal. Integrity depends on rigorous standards, robust governance and transparent verification. 

A high-quality carbon credit should demonstrate: 

• Additionality – the emission reduction or removal would not have occurred without carbon finance 
• Robust quantification and monitoring – emissions are measured using credible methodologies 
• Independent third-party verification 
• Permanence and risk management, where relevant 
• Safeguards to prevent environmental and social harm 

High-integrity credits provide confidence to buyers, investors and regulators, and strengthen trust in the market as a whole. 

Gold Standard was established to ensure that carbon finance delivers measurable climate impact while advancing sustainable development. 

All Gold Standard-certified projects: 

• Issue credits representing one tonne of verified CO₂e reduced or removed 
• Apply strong environmental and social safeguards 
• Incorporate inclusive, gender-sensitive stakeholder engagement 
• Contribute to at least three United Nations Sustainable Development Goals (SDGs), including SDG 13 (Climate Action) 

This integrated approach ensures that climate mitigation also supports communities, biodiversity and long-term resilience. 

In addition, Gold Standard continuously updates its methodologies and requirements to remain aligned with evolving science, policy and market expectations, including developments under Article 6 of the Paris Agreement and emerging integrity frameworks. 

For companies, voluntary carbon markets can support credible climate strategies when used responsibly. This means: 

• Prioritising deep emissions reductions within value chains 
• Using high-integrity credits to address residual emissions 
• Communicating transparently about claims and limitations 
• Aligning carbon finance with long-term transition planning 

When deployed thoughtfully, voluntary carbon finance can be a catalyst, accelerating mitigation, strengthening supply chains and delivering shared value for people and nature. 

Voluntary carbon markets continue to evolve. Increasing scrutiny, improved methodologies and stronger governance are shaping a more mature and robust market landscape. 

Gold Standard remains committed to ensuring that voluntary carbon finance delivers real, verified and equitable climate impact, and to supporting market participants in navigating this evolving space with integrity and confidence.
