Creating reliable carbon credit markets with blockchain and Decentralized Identity (DID) 🌿🌎

As the world races towards the development of transparent and reliable carbon credit markets, Seagrass, a climate action company subsidiary of E.ON, one of Europe's largest operators of energy infrastructure, announced the launch of a user-friendly and certified carbon marketplace named the Seagrass Carbon Map to facilitate trustworthy interactions between carbon credit suppliers and buyers.

To create seamless interactions and improve the transparency and verifiability of market participants, Seagrass partnered with The Hashgraph Association (THA), the non-profit organization accelerating the global adoption of the Distributed Ledger Technology (DLT) network Hedera worldwide, to co-finance the development of the Seagrass Wallet, a new generation of digital wallet built on Decentralized Identity (DID) standards and capable of supporting Verifiable Credentials, a new type of cryptographically secured document that is tamper-proof and instantly verifiable.

To craft this mobile wallet, Seagrass and THA chose Talao, the French company specialized in the development of ready-to-use and user-friendly Decentralized Identity (DID) solutions. Since 2017, Talao has crafted and launched dozens of successful digital wallets for its clients and is well-known for developing secure, open-source, and interoperable digital wallets based on open Self-Sovereign Identity (SSI) standards.

Furthermore, Talao is already compliant with European standards, such as the European Blockchain Services Infrastructure (EBSI) and is in the race to become one of the first European Digital Identity (EUDI) wallet providers in Europe by 2025, making it one of the best providers to craft secure, interoperable, and regulation-compliant digital wallets in Europe.

By using their Seagrass wallet, developed by Talao, to authenticate themselves on the Seagrass Carbon Map, participants will access a wide range of certified data points on the real-world carbon impact of projects, including environmental, economic, and project information. Once verified by Seagrass, users will be able to manage their verified credentials in their Seagrass wallet and instantly prove who they are to other market participants without having to undergo repeated due diligence or KYC checks, saving time and reducing costs.

"We are proud to work on this ambitious carbon project with Seagrass and The Hashgraph Association to unlock verifiability and transparency in the carbon credit markets by using Decentralized Identity and Verifiable Credentials."

Hugo MIR, Chief Marketing Officer (CMO) at TALAO

Seagrass Wallet is currently in testing and, if successful, will be made available to Seagrass clients in 2024. In the future, the project also aspires to make tokenized carbon asset management accessible to all participants through the DLT technology of Hedera, adding a new layer of traceability, transparency, and integrity to Seagrass carbon credit markets and accelerating the transition to net-zero emissions.
