Global Tree C-Sink

The Global Tree C-Sink is an innovative accreditation framework for climate services generated by living tree biomass, through afforestation, natural regeneration, or other tree planting interventions, such as urban forestry. 

Version 2.0 of the Global Tree C-Sink Standard builds on recent developments in high-integrity carbon markets and establishes a robust science-based approach that enables different project types, scales, and regional contexts.  

Key innovations of the Global Tree C-Sink Standard include:

• dMRV-focused accreditation, enabling transparent and cost-effective carbon accounting through precise digital tools.
• Dynamic valuation approach for temporary C-Sinks, reflecting the the nature of biomass C-Sinks to ensure fair pricing in voluntary markets.
• Efficient and transparent C-Sink registration and trading, facilitated through the Global C-Sink Registry.
• Integrated environmental and social safeguards, with criteria that promote biodiversity and community benefits.
• Project-specific eligibility and baseline criteria, designed to prevent land degradation and ensure credible climate impact.
• Improved guidance for Urban Tree and Plantation projects.
