Blockchain can significantly enhance transparency in the green energy certificate market. By leveraging decentralized ledgers, blockchain ensures immutable, traceable records of certificate issuance, trading, and retirement. Each certificate’s origin, ownership, and transaction history is verifiable in real-time, reducing fraud and double-counting risks. Smart contracts automate processes, ensuring compliance with regulatory standards and minimizing human error. This fosters trust among stakeholders, including producers, consumers, and regulators. Additionally, blockchain enables peer-to-peer trading, cutting intermediaries and costs while promoting market accessibility. However, challenges like high energy consumption of certain blockchains and integration with existing systems must be addressed to maximize benefits.
