Toucan, a project founded to revolutionize carbon offsetting, bridges physical carbon credits onto blockchain, creating tradable crypto tokens. Since its launch, Toucan has gained popularity, with a market cap reaching $100m. However, the impact of cryptocurrencies on the environment has raised concerns. Despite its rapid growth, Toucan faces criticisms and challenges, particularly in ensuring the integrity of carbon credits and addressing flaws in the voluntary carbon market. The project is seen as bringing technological efficiency to the carbon market, but questions persist about its long-term impact on real emissions reductions.
