TCO2: Toucan carbon tokens
TCO2
token contracts still carry all the attributes and metadata of the NFT, making them specific to a given project and vintage. This is crucial because voluntary market carbon credits trade at very different price points due to credits of a certain type or with specific attributes being more sought-after than others. This system guarantees that a soil carbon project with additional certification can be priced higher than a large-scale renewable energy project.TCO2
is the general term for fungible tokenized carbon credits. When you fractionalize a BatchNFT
, the ERC20 token will have TCO2-
as a prefix, followed by an information-rich name that includes the registry of origin, the project, the vintage, and so on.For example:
TCO2-GS-0001-2019
However, there's one downside to this: because they are specific to a single project and vintage,
TCO2
tokens are not very liquid. While in the example above it makes sense to discriminate between the two tokens, what if we want to create a liquid market for soil carbon where all soil carbon credits are treated equally? This would allow deep liquidity to be aggregated, key for fair and efficient price discovery for a specific type of carbon asset—something we are struggling to find in the "real world".Last modified 6mo ago
