Leveraging Blockchain for Scalable Climate Impact
A new wave of innovation is reshaping how the voluntary carbon market operates. Alongside emerging frameworks and regulations, blockchain technology is driving greater transparency, efficiency, and trust.
This transformation is essential — the VCM must scale tenfold in the coming years if humanity is to meet its climate goals. Modernizing the entire carbon market infrastructure is key to making it both high-integrity and future-ready.
