Green x Digital Consortium Releases
Technical Specifications for Data Exchange (Version 1.0)
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 released its Technical Specifications for Data
Exchange (Version 1.0), which lays out technical specifications (data items, a common dataformat, and API linkage specifications, etc.) for CO2 data*1 shared across the supply chain
using digital technology. These specifications are designed to enable global-level crossindustry CO2 data linkage and incorporate internationally accepted specifications. Theirutilization will enable data exchange across solutions, contributing to the realization of CO2
data visualization throughout the supply chain from upstream to downstream.
There is a strong call to achieve decarbonization throughout the supply chain in all industries
so as to realize carbon neutrality by 2050. For those greenhouse gases emitted in the courseof business activities in the supply chain, we need to accurately assess and reduce CO2 acrossthe supply chain, including direct emissions (Scope 1), indirect emissions from the generationof purchased energy (Scope 2), and all other indirect emissions occurring in upstream anddownstream activities (Scope 3). While various CO2 data visualization solutions have beendeveloped, the lack of common specifications to link data between different solutions has
made it difficult to grasp CO2 data from upstream to downstream in the supply chain whendifferent solutions are being used.
The Green x Digital Consortium’s Visualization Working Group (led by Kōichi Inagaki, NECCorporation) accordingly launched the Data Format and Linkage Sub-Working Group (led byTakuya Nagamiya, Fujitsu, Ltd.) in April 2022 to present a common data format and linkagespecifications (a data platform, etc.) for sharing CO2 data using digital technology. The Tech
Specs for Data Exchange (Version 1.0) created by the Data Format and Linkage SWG werereleased today as a methodology based on the Pathfinder Network developed by theinternational framework WBCSD Partnership for Carbon Transparency (PACT)*2 that also
takes into account the needs of companies participating in the Consortium as well as domesticsystems.
These technical specifications form a set with the CO2 Visualization Framework*3, a CO2 data
calculation methodology announced by the Green Digital Consortium on June 30, 2023. Byusing the “common language” of the data calculation methodology and the technicalspecifications, companies developing solutions for CO2 data visualization will be able toachieve data linkage among multiple solutions. There will also be no need to make individualadjustments to other companies’ specifications, which will boost development efficiency.
User companies will now have a much wider range of options when they introduce solutions.
Even if a company and its suppliers use different solutions, they will be able to transfer CO2
data without doing anything extra, helping to realize CO2 data visualization in the supply
chain. For more details on the specifications, please see our website.

Comment from WBCSD PACT:Our partnership with the Green x Digital Consortium demonstrates the value of acollaborative and interoperability-focussed approach to enabling value chain transparency.
Thanks to Green x Digital’s facilitation, organizations ranging from startups to corporationshave collaborated and contributed to PACT. Green x Digital members have createdinteroperable technology solutions and implemented the PACT Framework and related
technological foundations through supplier engagement programs. We congratulate andrecommend Green x Digital for their significant contributions to the field of value chaintransparency in Japan, and look forward to continued collaboration.

CO2 data
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.

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 TechnicalSpecifications. The Green x Digital Consortium participates in the PACT ecosystem.

CO2 Visualization Framework
A methodology document developed by the Methodology Sub-Working Group (led byMasahiko Shibata, Mizuho Research & Technologies, Ltd.), laying out calculations andcommon rules on CO2 exchange in the supply chain using digital technology so as to realize
CO2 data distribution based on primary data that reflect suppliers’ emission reduction efforts.
The Framework adopts the approach of the WBCSD PACT Pathfinder Framework while alsotaking into account the needs of companies participating in the Consortium as well as
domestic systems.

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 as
visualization 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).
