Global Tree C-Sink

Global Tree C-Sink

The Global Tree C-Sink standard is a novel certification guideline for the reliable quantification and adequate valuation of climate services generated by living plant biomass in either new plantations or natural afforestation. 

Some basic pillars:

  • Global C-Sink Registry: Integrates a transparent and secure platform for registration of carbon sinks and trading.
  • Robust C-sinks: Offers carbon sinks based on yearly verifications, avoiding the issuing of non-verifiable future credits.
  • On-Site Inspection: Prescribes regular checks that ensure global warming mitigation effects.
  • Annual Tree Health Checks: Prioritizes the stability and reliability of the projects.
  • Biodiversity and Resilience: Includes criteria for species diversity and native tree conservation that promote ecological benefits.
  • Sustainable Forest Management: Prohibits practices that lead to deforestation and forest degradation.
The Global Tree C-Sink standard demonstrates a comprehensive approach to sustainable forestry and climate change mitigation. This holistic approach not only addresses the environmental aspects but also ensures the maintenance of biodiversity and ecological balance, making it a promising option for those seeking an effective and trustworthy tree standard.

With Global Tree C-Sink, we expect an epochal shift in the fight against climate change, which is why we have also integrated biodiversity criteria into the standard.
