Distributed Settlement Mechanism Design for Carbon Market Based on Blockchain-Enabled Edge Intelligence

The trend towards decarbonizing the power industry is accelerating due to the environmental crisis. The development of carbon markets as one of the solutions for decarbonization has received more attention. The current annual carbon market widely adopts the method of calculating carbon emission according to the average carbon emission factor. The roughness of the average carbon emission factor and the long carbon market cycle lead to some problems in carbon market settlement in the carbon market at present. In this paper, we propose a blockchain-based scheme for real-time local settlement of carbon emissions. The system obtains accurate carbon emission information of generating units calculated from real-time power information through IoT devices. The digital carbon asset stored in the unit's account are written off in a short period through a blockchain smart contract. The above scheme eases the communication burden caused by accurate carbon emission records. With hardware devices, we verify the feasibility and operability of the scheme.
