[0061] In the embodiments of the present application, the core of the electricity carbon emission data storage system is a hierarchical blockchain platform, which provides services for power supply bureaus, carbon emission users and environmental protection monitoring departments, and realizes large-scale electricity carbon emission data storage and synchronization. The hierarchical blockchain platform provides an identity registration interface, a data upload interface and a data download interface. The power supply bureau registers the identities of the environmental protection monitoring departments and the carbon emission users through the identity registration interface, and issues certificates for accessing the blockchain; the carbon emission users upload electricity carbon emission data to the blockchain through the data upload interface; and the environmental protection monitoring departments download the uploaded electricity carbon emission data of target users (such as carbon emission users such as emission control enterprises, power generation facilities, metering facilities and energy storage facilities) through the data download interface.
