Decentralised Carbon Exchange

Today's voluntary carbon market lacks the necessary liquidity for efficient trading, partly because carbon credits are highly heterogeneous. Each credit carries specific attributes tied to the underlying project, such as the project type or the region where it was conducted.

These attributes influence the credit's price, as buyers place different values on additional features. This inconsistency among credits means that matching an individual buyer with a corresponding supplier is a time-consuming and inefficient process, typically transacted over the counter.

Greenearth’s Carbon Exchange is built on the Hbarsuite NFT DEX platform. By transforming a carbon removal credit into an NFT and recording it on-chain, the credit can be priced to reflect the underlying quality of the sequestration. This alignment of price and quality can unleash the market forces needed to incentivize the generation of high-quality credits.

The NFTs created from carbon credits are recorded on the blockchain. When these NFTs are used in offsetting or insetting activities, they will be "burned." This ensures that each carbon credit is used only once, maintaining the integrity of the market and preventing double counting or other forms of misuse.
