Green x Digital Consortium
succeeds in joint POC experiment with 32 companies on CO2 data linkage in a virtual
supply chain, lends momentum to supply chain CO2 data visualization
The Green x Digital Consortium, for which the Japan Electronics and Information
Technology Industries Association (JEITA; chaired by Keiji Kojima, President & CEO,Hitachi, Ltd.) serves as secretariat, today announced the success of its proof-of-concept(POC) experiment with CO2 data linkage in a virtual supply chain, aimed at realizing supplychain CO2*1 data visualization. This was the first experiment to be conducted in Japan with aneye to global-level cross-industry CO2 data exchange. Its success will lend momentum toutilization of the CO2 data calculation method and technical specifications created by theConsortium, helping to realize CO2 data visualization throughout the supply chain.
The whole experiment comprised two phases, with Phase 1 in January 2023 successfully
testing CO2 data linkage across different solutions. Phase 2, which we just completed,brought in 32 companies to test aspects such as actual CO2 data calculation by solution users.
Specifically, we built a virtual supply chain consisting of three layers—materials, processedmaterials, and products—taking a computer as our product. We then allocated theparticipating companies to the respective layers and had them perform CO2 data calculations
using the CO2 Visualization Framework created by the Consortium’s Visualization Working
Group (led by Kōichi Inagaki, NEC Corporation) and then exchange CO2 data among
solutions based on the Tech Specs toward Data Exchange.*2 By calculating CO2 data for allelements from materials through to the final product and passing that data among different
companies and different solutions, we succeeded in visualizing the CO2 data for a final
product based on a shared understanding among all the companies in a supply chain.
Through Phase 2, we demonstrated that even if the multiple companies making up a supply
chain use different CO2 data visualization solutions, as long as they use the same method andformat—the same language, as it were—to calculate CO2 data, multiple solutions can belinked to enable CO2 data to be transferred from upstream to downstream in a supply chain.
We look forward to the widespread uptake of the CO2 Visualization Framework and Tech
Specs toward Data Exchange used in the experiment increasing the number of options foruser companies when introducing solutions, as well as eliminating the need for solution
providers to align their solutions to individual companies and thereby enhancing theirdevelopment efficiency, contributing to the early realization of CO2 data visualization in thesupply chain.
Looking ahead, we will use the findings from the POC experiment to update the CO2Visualization Framework and Tech Specs toward Data Exchange as frontrunning initiatives
designed for ease of use by as many companies as possible, while ensuring the global-levelinteroperability of these. To that end, we will also strengthen our partnership with theinternational framework WBCSD Partnership for Carbon Transparency (PACT)*3, Further
information will be released as work proceeds.

Refers in the press release and in the CO2 Visualization Framework to CO2-equivalentgreenhouse gas emissions (expressed as kg CO2e, etc.) as stipulated by the IPCC. Includes
greenhouse gases other than carbon dioxide.
*2Carbon visualization framework and technical specifications for data exchange
The carbon visualization framework comprises a document outlining a methodology forusing data technologies to calculate and share carbon data (disclose data quality) exchanged
within the supply chain with the aim of realizing carbon data distribution based on primarydata that reflects supplier companies’ emissions reduction efforts. The technical specifications
incorporate the approaches of the WBCSD PACT’s Pathfinder Network and Pathfinder
Framework along with unique elements based on Japan’s domestic systems and the needs ofcompanies participating in the Consortium. Preparations are currently underway to disclose
the framework and the specifications to the general public.

WBCSD Partnership for Carbon Transparency (PACT)The World Business Council for Sustainable Development comprises a coalition of CEOs
from around 200 companies aiming to realize sustainable development. The WBCSD is themain convener of the GHG Protocol. PACT was set up under the auspices of the WBCSD toboost emissions transparency in the value chain and accelerate decarbonization. It defines thenecessary methodologies and technical specifications for emissions data exchange, which it
releases in the form of the Pathfinder Framework and the Pathfinder Network Technical
Specifications. The Green x Digital Consortium participates in the PACT ecosystem.

Green x Digital Consortium
The Consortium was established in October 2021 to help realize carbon neutrality by 2050
through the digitalization of environment-related fields and the creation of new businessmodels. It promotes collaborative creation among Consortium members on themes such asvisualization of CO2 emissions in the supply chain and the introduction of renewableenergies. The Consortium is headed by Professor Noboru Koshizuka (Graduate School ofInterdisciplinary Information Studies, The University of Tokyo) and has 155 members (as ofAugust 4, 2023).
