Description
Technical Field
The invention relates to the field of industrial enterprise carbon emission, in particular to a method for calculating and tracing carbon emission based on identification analysis and blockchain.
Background
The current industrial carbon management platforms developed by different bodies are not consistent in terms of their accounting methodologies, and there may be methodologic variations in the individual carbon management platforms as different versions of the product are developed. This can lead to a lack of continuity in the accounting of carbon emissions by the enterprise, and a lack of consistency in the carbon emissions calculated by the different platforms, which can present a barrier to the industrial carbon management platform user. With respect to carbon emission management technology, carbon emission management ledgers of most enterprises are currently recorded and stored in the form of electronic forms. Although the method is convenient for recording the carbon emission information of enterprises, and has lower operation technical requirements, the risk of mistakes or loss of related information caused by artificial reasons exists.
The identification system, the industrial Internet identification analysis system gives each entity or virtual object unique identity code in the modes of bar codes, two-dimensional codes, radio frequency identification tags and the like, and simultaneously carries related data information, so that novel infrastructure of positioning, connection and conversation of the entity and the virtual object is realized. The identification analysis system is considered as the foundation in the foundation of the industrial Internet, is a nerve for supporting interconnection and interworking of the industrial Internet, and is a key core facility for driving innovation and development of the industrial Internet. Which functions similar to the domain name resolution system (DNS) in the internet domain.
Blockchains, which are a shared, non-tamperable ledger, are intended to facilitate transaction records and asset tracking processes in business networks. Assets may be tangible (e.g., houses, cars, cash, land) or intangible (e.g., intellectual property, patents, copyrights, brands). Almost anything of value can be tracked and traded over the blockchain network, thereby reducing the risk and cost of the various aspects. The blockchain database stores data in blocks, and the databases are linked together into a chain. The data is consistent in time because the chain cannot be deleted or modified without network consensus. Thus, a blocking chain technique may be used to create an unalterable ledger in order to track orders, payments, accounts, and other transactions.
