Green x Digital Consortium Releases CO2 Visualization Framework (Edition 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 CO2 Visualization Framework(Edition 1.0), which indicates methods of calculating and sharing CO2 data*1 exchanged inthe supply chain using digital technology (data quality disclosure methods). The first effortin Japan to visualize CO2 data across the supply chain, the Framework is designed to enableglobal-level cross-industry CO2 data exchange and presents an internationally-consistentmethodology for data calculation and sharing.
There is a strong call to achieve decarbonization throughout supply chains in all industries
so as to realize carbon neutrality by 2050. This will require the accurate assessment andreduction of CO2 across the supply chain, including not just direct emissions (Scope 1) andindirect emissions from the generation of purchased energy (Scope 2) but also all indirectemissions (not included in Scope 2) that occur in the value chain of the reporting company,
including both upstream and downstream emissions (Scope 3).
However, there has previously been no common methodology for exchanging CO2 datapremised on the provision of data from suppliers, disparities in data collection andcalculation arising from different boundaries*2 have resulted in CO2 data of uneven quality.
Precise CO2 data enables visualization of which stages in the supply chain have the greatest
CO2 emissions, as well as of the results of emission reduction efforts, while circulating
examples of emission reduction within the industry and then spreading them industry-wide
as well as to other industries will contribute to the reduction of greenhouse gas emissions
across Japan as a whole.
The Green x Digital Consortium’s Visualization Working Group (led by Koichi Inagaki, NECCorporation) accordingly launched a Methodology Sub-Working Group (led by MasahikoShibata, Mizuho Research & Technologies, Ltd.) in April 2022 to create a common
methodology for CO2 data calculation premised on CO2 data exchange that would be basedon primary data and reflect suppliers’ emission reduction efforts. The CO2 Visualization
Framework (Edition 1.0) created by the Methodology Sub-Working Group was released
today as a methodology based on the Pathfinder Framework, an international framework
developed by the WBCSD Partnership for Carbon Transparency (PACT) *3, that also takes
into account the needs of companies participating in the Consortium as well as domesticsystems.
The CO2 Visualization Framework (Edition 1.0) assumes utilization by all businesses
engaged in supply chain CO2 data visualization and exchange using digital technology. In
particular, the Framework’s detailed explanation of how companies in the supply chain canrealize high-level CO2 data calculation and sharing should open the way for utilization of

the Framework by many companies in the supply chain and, consequently, an accurate
understanding of supply chain CO2 data. Please see the following website for more
information.

In addition, the Data Format and Linkage Sub-Working Group (led by Takuya Nagamiya,Fujitsu Ltd.), which was established at the same time as the Methodology Sub-WorkingGroup, has developed Technical Specifications toward Data Exchange that lay out
specifications and formats for data exchange. These are currently being reviewed toward
public release. Phase 1 of proof-of-concept work on both the Framework and the Technical
Specifications began in September 2022, followed by Phase 2 in October 2022. With thiswork now successfully concluded, details of the results will be released in early August thisyear.
*1 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.
*2 Boundary

Indicates the scope within which CO2 data is calculated. May also indicate the boundary for
product systems and processes not included in those systems, as well as for specific processes.
Examples include manufacturing process boundaries, use process boundaries, andboundaries for the scope of collection of CO2 data at manufacturing sites, offices, and factory
grounds, etc.
*3 WBCSD Partnership for Carbon Transparency (PACT)WBCSD is the premier global, CEO-led community of over 200 of the world’s leading
sustainable businesses working collectively to accelerate the system transformations needed
for a net-zero, nature positive, and more equitable future. The Partnership for Carbon
Transparency (PACT) seeks to accelerate decarbonization through the creation oftransparency on emissions in the value chain. The PACT community defines and publishes
the necessary methodological and technological basis for emissions data exchange,
integrating existing standards and approaches and creating a trusted and holistic
foundation. The PACT is hosted by the WBCSD. The Green x Digital Consortium
participates in the PACT ecosystem.

Green x Digital Consortium
The Green x Digital Consortium (Chair by Noboru Koshizuka, Professor, Interfaculty
Initiative in Information Studies, The University of Tokyo) was launched in October 2021
with the aim of realizing carbon neutrality across society by 2050. The consortium brings
together companies from all business types and industries that use digital technologies
to work on carbon data visualization and introduction of renewable energy. The numberof members reached 151 members (as of May 26, 2023).
