Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of industrial energy saving, more specifically, it relates to a method, system and device for managing carbon footprint of electrolytic aluminum products based on a blockchain. BACKGROUND

[0002] Under the global low-carbon development trend and the "double carbon" target, the requirement for carbon emission management in the industrial field is continuously improving. As a high energy-consuming industry, electrolytic aluminum, the quantification and management of its product carbon footprint has become a key link in green transformation. Related policies and industry standards clearly state that the reliability and management efficiency of carbon footprint data need to be improved through technological innovation to support the green and collaborative development of the industry chain. Under this background, the demand for technological upgrading of electrolytic aluminum industry carbon footprint management is increasingly urgent.

[0003] Currently, the management of electrolytic aluminum product carbon footprint mainly relies on traditional manual accounting and centralized data storage mode. Enterprises need to independently collect energy consumption data (such as electrolytic cell power consumption, fuel consumption), raw material usage data (such as alumina consumption, anode carbon block usage) and logistics transportation data throughout the production process, manually organize them, and then calculate them according to industry standards to form a carbon footprint report and submit it to a third-party organization for certification. Data is stored in enterprise self-built databases or third-party centralized platforms, and the collection, transmission and verification process mainly relies on manual intervention, lacking automated and standardized technical support.

[0004] The traditional technical mode has significant defects, which restricts the effectiveness of carbon footprint management. First, the data authenticity and credibility are insufficient. Manual recording and self-reporting methods can easily lead to data distortion, such as production energy consumption data may deviate due to operational errors or human intervention, making it difficult to accurately reflect the actual carbon emission level and failing to meet the core requirement of data authenticity for carbon footprint certification. Second, the supervision efficiency is low and there are blind spots. Supervisors obtain data from reports submitted by enterprises or centralized platforms, which cannot track the dynamic of carbon footprint throughout the industry chain in real time. Data is scattered and stored in various subjects, making it difficult to integrate across links, leading to a lag in identifying abnormal behavior and making it difficult to achieve precise supervision.

[0005] In addition, the data island phenomenon is prominent, and the industry chain collaboration is hindered. The carbon footprint of electrolytic aluminum products covers the whole life cycle of mining, smelting, transportation, processing, etc., and the data of each subject is difficult to interconnect due to ownership and technical barriers. For example, production enterprises need to spend a lot of resources to manually interface data with upstream suppliers and logistics enterprises, not only increasing the accounting cost, but also causing gaps in the whole life cycle of carbon footprint traceability. With the increasing requirements for data credibility, real-time and collaboration in the industry, the shortcomings of traditional technology in data evidence, automated management and cross-subject collaboration are becoming more and more obvious, and new technical solutions are urgently needed to solve the problems of data trust and efficiency.
