Green x Digital Consortium:
Successful CO₂ data exchange throughout a virtual supply chain

Cyanoba used in validation of CO₂ data calculation practices by user companies

　The Green x Digital Consortium (Secretariat: Japan Electronics and Information Technology Industries Association [JEITA]), in which ABeam Consulting Ltd. participates, has conducted a successful proof-of-concept experiment linking CO₂ data for exchange throughout a virtual supply chain as part of its efforts to bring visibility to supply chain CO₂ data.^*1
　The latest proof-of-concept experiment is Phase 2 of the first trial of its kind in Japan aimed at achieving cross-industry CO₂ emissions data exchange on a global level. It follows the successful Phase 1 proof-of-concept experiment on CO₂ data linkage between different solutions in January 2023.

　ABeam Consulting has been participating as a solution provider for this pilot project since Phase 1, with its Cyanoba service, a joint offering with PID Inc. While referring to the results of the Phase 1 CO₂ data linkage test among solutions of 15 companies, we participated in this Phase 2 proof-of-concept test by incorporating actual CO₂ data acquisition and calculation together with a total of 32 companies including users.
　Cyanoba, the solution provided by ABeam Consulting, is a GX management tool with the ability to centrally manage energy usage/emissions data along with cost information, and is expected to contribute to the Green x Digital Consortium's goal of achieving carbon neutrality by 2050 through initiatives for digitalization and the creation of new business models. This solution is expected to make it possible to accurately track the reduction efforts of companies working to cut CO₂ emissions through collaboration across supply chains.

■Details of this Proof-of-Concept Experiment
　A total of 32 companies from the Green x Digital Consortium, including ABeam Consulting, participated in the Phase 2 proof-of-concept experiment, which included CO₂ data calculation practices. Specifically, a virtual supply chain consisting of three layers, for basic materials, processed materials, and products, was constructed using personal computers as the subject product, with each participating company located on its respective layer. Calculations of CO₂ data were performed based on the CO₂ Visualization Framework formulated by the consortium's Working Group on CO₂ visualization (led by Kazu Inagaki, NEC Corporation), and linkage of CO₂ data among solutions was based on the Technical Specifications for Data Exchange.^*2 In calculating CO₂ data throughout the process from materials on through to finished products, passing between different companies and different solutions, we have succeeded in calculating (and thereby visualizing) CO₂ data for final products based on the common understanding of all companies in the supply chain.

　As a result, we demonstrated that even if multiple companies in a supply chain use different CO₂ data visualization solutions, they can calculate CO₂ data using shared methods and formats as a "common language" enabling them to pass CO₂ data through the supply chain from upstream to downstream by linking up multiple solutions. The spread of the CO₂ Visualization Framework and Technical Specifications for Data Exchange used in this study is thus expected to lead to the early realization of supply chain CO₂ data visualization, since it will enable user companies to make a wider range of choices when introducing solutions, and also allow companies that provide solutions to streamline their development by eliminating the need for individual coordination with other companies.

■Final Report on POC Experiment Phase 2

■Efforts of ABeam Consulting Phase 2
　ABeam Consulting was responsible for CO₂ data calculation and linkage of basic materials and processed materials within the virtual supply chain. We had user companies actually apply Cyanoba to the task, and demonstrated that it is possible to calculate CO₂ emissions related to basic materials and processed materials, and to link such data across multiple solutions.

　ABeam Consulting will continue beyond this project with our contributions to efforts to solve social issues by helping companies achieve both GX and business growth through the use of data and digital technologies in the decarbonization field.
