Description

Technical Field

[0001] The present invention belongs to the technical field of traceability authentication, and in particular relates to a method and system for traceability authentication based on carbon footprint of green alcohol fuel. Background Art

[0002] With the International Maritime Organization's adoption of the "2023 Ship Greenhouse Gas Emissions Reduction Strategy" and the release of a series of international policies such as the EU's inclusion of the shipping industry in the carbon emissions trading system, green methanol, as a clean energy produced from biomass, industrial waste gas and other renewable resources, has become the core choice for the shipping industry to decarbonize. However, with the promotion of green alcohol fuel, how to prove that ship fuel is green alcohol fuel has become a pain point in the industry. Accurately tracing and certifying the carbon footprint of ship fuel throughout its life cycle has become a good solution. Carbon footprint traceability is a process of tracking and calculating carbon emission data during energy production, transportation, and use to comprehensively assess its environmental impact. It can not only certify that ship fuel is green alcohol fuel, but also provide transparent and reliable carbon emission reduction information to enterprises, governments and consumers, and contribute to the green and low-carbon economy.

[0003] At present, the traceability system is applied in the food, medicine, construction and other industries, including China Traceability Cloud Public Service Platform, Food Safety Anti-counterfeiting Traceability System Platform, China Food Safety Traceability Platform, China Bird's Nest Traceability Management Service Platform, and traceability system based on RFID technology and electronic tag anti-counterfeiting technology. However, there is still a lack of a unified traceability certification system in the shipping industry. At the same time, most of the existing traceability systems use centralized databases to store privacy data, which is prone to single point failures and information leakage. Blockchain technology can ensure that the data recorded on the chain cannot be tampered with and is traceable throughout the process through encryption algorithms and consensus technologies, providing guarantees for carbon footprint traceability certification. Therefore, how to effectively combine blockchain with green alcohol fuel carbon footprint traceability certification can ensure the authenticity, timeliness and reliability of carbon footprint traceability certification while ensuring data security.
