Fujitsu has announced the launch of a demonstration experiment focused on validating the flow of environmental value associated with green steel across the steel industry’s supply chain. The initiative began in December 2025 and follows its earlier selection by Japan’s Ministry of Economy, Trade and Industry as part of the fiscal year 2025 Industrial Research Project. The government-backed program was centered on studying how green steel information linked to steel materials can be transmitted effectively across supply chains, reflecting growing policy and industry attention on decarbonization.
The demonstration is scheduled to run from December 2025 through February 2026. Fujitsu has positioned the project as a practical effort to address the challenge of ensuring that the environmental value created through low-emission steel production can be securely and accurately transferred from upstream producers to downstream users. By validating this value flow, the company aims to support broader decarbonization efforts within manufacturing, starting with one of the most carbon-intensive sectors.
Applying Digital Technologies to Emissions Reduction
The experiment draws on Fujitsu’s expertise in materials related to carbon dioxide emissions reduction, blockchain technology, and secure data distribution platforms. These technologies are being combined to create an environment in which data can be shared safely while maintaining transaction confidentiality. Fujitsu has indicated that the objective is to protect both the integrity of environmental value data and the commercial sensitivity of transactions taking place along the supply chain.
Through this initiative, the company seeks to contribute to environmental action and digital transformation within the steel industry. The project is also expected to generate insights that will inform the development of future mechanisms for distributing green steel information more broadly. Based on the findings, Fujitsu plans to examine opportunities from 2026 onward to expand such mechanisms into a wider steel industry data space, potentially enabling more standardized and scalable data sharing.
Supporting Sustainable Industry Through Uvance
The project aligns with Uvance, Fujitsu’s business model focused on solving societal challenges through digital innovation. Under this framework, Fujitsu aims to establish a mechanism that allows reliable environmental value data to be shared and utilized securely and flexibly across national borders and industry sectors. The company has suggested that enabling trusted data exchange at this level could enhance corporate competitiveness while supporting the transition toward a more sustainable society.
Reducing carbon dioxide emissions from steel production has become an urgent societal issue, given the industry’s significant contribution to global emissions. Although steel producers have begun supplying green steel using recognized approaches such as mass balance and allocation methods under established guidelines, challenges remain. In particular, the environmental value generated at the production stage is not always transmitted effectively to downstream companies, limiting its impact and recognition across the full supply chain.
Project Structure and Key Objectives
The demonstration experiment is designed to examine how environmental value, including emissions reduction certificates issued by steel manufacturers, can flow from upstream producers to downstream users without being duplicated, diluted, or compromised. A central focus is on preventing double-counting of environmental value while preserving its credibility as materials pass through intermediate processors and multiple distribution channels.
As part of the project, Fujitsu is building a data distribution platform that ensures traceability of company and industry data. The platform leverages Fujitsu Sustainable Value Accelerator, a solution under Uvance that supports green transformation initiatives. With cooperation from various steel-related businesses, the experiment involves distributing third-party certified green steel certificates in a controlled environment.
These certificates are used to verify the uniqueness of environmental value and confirm that it remains intact throughout the supply chain. By testing this approach, Fujitsu also aims to identify practical and operational challenges faced by different business operators when such mechanisms are applied in real-world settings.
Toward a Decarbonized Steel Supply Chain
Through this demonstration, Fujitsu is seeking to establish a foundation for more transparent and trustworthy green steel supply chains. The company views the project as an important step toward ensuring that environmental value is properly recognized and transferred, supporting both regulatory compliance and corporate sustainability goals. If successful, the initiative could serve as a model for broader adoption of digital systems that link environmental performance with industrial supply chains.
