The popularization of the ESG investment concept is driving climate-related crypto projects into a new stage. Statistics show that the growth momentum of green on-chain ecosystems is strong: KlimaDAO's carbon credit token trading volume has surged by 500% month-on-month, with its treasury assets reaching a carbon offset quota of 20 million tons; Toucan Protocol, as a key carbon bridging solution, successfully on-chainizes traditional carbon market assets, with an overall valuation surpassing $500 million; meanwhile, the total locked assets in the ReFi (Regenerative Finance) track have approached $4 billion, covering various application fields such as renewable energy and regenerative agriculture. International developments are also worth noting—the United Nations Framework Convention on Climate Change recently announced a partnership with the Global Blockchain Climate Alliance, aiming to enhance data transparency and trading efficiency in the carbon market through distributed ledger technology. According to Goldman Sachs' research team, if current development trends continue, the tokenized carbon market could reach a scale of $500 billion by 2030.
