The demonstration experiment runs from December 2025 to February 2026 and focuses on the secure distribution of environmental value data associated with green steel. Fujitsu is applying its expertise in materials-related carbon dioxide emissions reduction, blockchain technology and data distribution platforms to ensure data integrity, transaction confidentiality and the reliable transmission of environmental attributes.
The project examines how environmental value, including emissions reduction certificates issued by steel manufacturers producing green steel, can be transferred through supply chains from upstream producers to downstream users without duplication or loss. It also assesses operational and business challenges that may arise for individual supply chain participants when such mechanisms are implemented.
As part of the experiment, Fujitsu is establishing a data distribution platform designed to ensure traceability of company and industry data. The platform utilises Fujitsu Sustainable Value Accelerator, a solution under the company’s Uvance business framework that supports green transformation initiatives. In cooperation with steel industry stakeholders, the experiment includes the distribution of third-party certified green steel certificates to verify the uniqueness of environmental value, prevent double counting and maintain certificate validity when materials pass through intermediate processors or alternative distribution routes.
Based on the findings, Fujitsu plans to explore the development of mechanisms for the broader distribution of green steel information and the potential expansion into a steel industry data space from 2026 onward. The company aims to support environmental initiatives and digital transformation within the steel sector while contributing to the establishment of supply chains capable of securely sharing reliable environmental value data across national and industrial boundaries.
