Toucan told WSJ it’s working to overhaul the voluntary carbon market in part by providing real-time pricing information and a public record of trades to track who can take credit for funding projects to improve the climate.Â
The report noted that trading in BCT has been driven by Klima, a separate crypto asset run by KlimaDAO. The decentralized autonomous organization allows people to buy Klima tokens, which are traded on cryptocurrency exchanges, with BCT tokens. The DAO then keeps the BCT tokens in its treasury, removing them from circulation. More than 14 million BCT tokens have followed this route and can’t be used for carbon offsets.
The WSJ reported that the mostly anonymous developers of Klima say their tokens also help the climate by reducing the availability of carbon credits and pushing up their prices. In turn, that should…
