Information Disclosure based on the TCFD Recommendations

The progress of IIJ Group's initiatives for the TCFD(*)'s disclosure recommendations of "Governance," "Strategy," "Risk Management" and "Metrics and Targets" is as follows.

Governance and Risk Management

IIJ believes that the fulfilment and implementation of corporate governance play an important role both in putting its management philosophy into practice and continuously enhancing its corporate value. IIJ has established and operated a corporate governance system to ensure these fulfilments. Under the corporate governance system, the Sustainability Committee, chaired by the president, has been established as an organization under the direct control of management to deal with the increasing importance of responding to sustainability-related risks and opportunities in recent years such as climate change, and to promote company-wide initiatives across the entire company. With regard to climate change related issues, IIJ continues to engage in the relevant initiatives in accordance with the "Policy for Environmental Initiatives," and also identifies, assesses and manages climate change related risks and opportunities from diverse perspectives by cross-sectional members from corporate planning, technology, finance, public relations, human resources and other departments. The initiatives of the Sustainability Committee are regularly reported to the Board of Directors, and risks identified by the Sustainability Committee that could have material impacts on the business are integrally managed together with other business risks, which are continuously identified, assessed and managed by the Board of Directors.

Activities of the Sustainability Committee

(As of the end of June 2024)

Committee meetings	Four times（2023.07-2024.06）
Report to the Board of Directors	Once

In addition to the above initiatives, IIJ has established and operated an environmental management system that covers the business activities of the data center department, and has obtained international environmental management system certification (ISO 14001: 2015), which is designed to minimize the impact of corporate and other activities on the environment.

Strategy

The TCFD recommends that analyses include the 2℃ or lower scenario, which is based on the Paris Agreement's targets. IIJ selected the 2℃ or lower scenario for its "Scenario Analysis" in line with the recommendation. The "Scenario Analysis" was conducted by setting the year 2030 as a point in time in consideration of the rapid progress of information technology and others. In the first year of the "Scenario Analysis" (FY2021), the analysis was conducted only for IIJ, and from FY2022 onwards, the major subsidiaries IIJ Global Solutions (IIJGS) and IIJ Engineering (IIJEG) have been included in the analysis in consideration of their business scale and the impact of climate change on their operations.

The table below shows the risks and opportunities related to climate change identified by IIJ, IIJGS and IIJEG that could have material impacts on their businesses, measures to address them, and impacts on their businesses, strategies and others. As for physical risks such as increased occurrence of typhoons and floods, prolonged high temperatures, and sea level rise, IIJ recognizes that the impact on its business and strategies is low due to the selection of data center sites in consideration of hazard maps, and redundant designs of network circuits and equipment. Meanwhile, the use of electricity is essential for the provision of network related services, and IIJ believes that implementing measures such as the use of renewable energy and improvement of energy efficiency at data centers, which consume a large amount of electricity, is an important initiative to address transition risks and opportunities, including stricter laws and regulations toward a decarbonized society, increasing demand for low-carbon emission services, and increasing social demand for environmental responsibility. IIJGS mainly provides network services such as WAN, and its risks and opportunities related to climate change are common to those related to IIJ's network services. IIJEG mainly provides data center services and others to IIJ, and the risks and opportunities related to climate change are common to those related to IIJ's data center services.

Metrics and Targets

Policy for Greenhouse Gas Reduction Initiatives at IIJ's Own Data Centers

IIJ Group contributes to the reduction of greenhouse gas emissions in society as a whole by improving the efficiency of social activities through the provision of network related services and by sharing computer resources through the provision of cloud services. However, the use of electricity is essential for delivering these services.
IIJ recognizes the importance of reducing greenhouse gas emissions at its own data centers, which consume about 80% of all electricity consumption, by "usage of renewable energy(*1)" and "improvement of energy conservation". The targets for each of initiatives, and FY2023 results, are as follows.

Measures	Targets	FY2023 results
Usage of renewable energy	The target is to increase the renewable energy usage rate of data centers (Scope 1 and 2(*2)) to 85% in FY2030.	50% (Matsue data center has continued to achieve 100% renewable energy utilization)
Improvement of energy conservation	The target is to keep the PUE(*3) of the data center at or below the industry's highest level(*4) until FY2030 through continuous technological innovation.	Matsue data center: 1.33 Shiroi data center: 1.36 (Continued to achieve industry's highest level PUE of 1.4 or lower).

• (*1)Renewable energy: Including substantial renewable energy through the use of non-fossil fuel certificates
• (*2)Scope 1 and 2 (Greenhouse gas emissions by a company): Direct emissions from the use of fuels and industrial processes at the company and indirect emissions from the use of electricity and heat purchased by the company (as defined by the GHG Protocol)
• (*3)PUE (Power Usage Effectiveness) : Total data center facility energy usage divided by IT equipment energy usage
• (*4)Industry's Highest Level PUE : PUE 1.4 or lower (As of March 31, 2024, the Agency for Natural Resources and Energy has set a benchmark index and target level of PUE as 1.4 or lower in the data center sector, and operators that achieve this are considered excellent energy conservation operators.)

Results of initiatives

Track record of initiatives in IIJ's own data centers.

IIJ's electricity consumption at its own data centers in FY2023 increased by 27% year-on-year mainly due to the expansion of its business scale and increased utilization of its own data centers associated with the consolidation of data centers leased from other companies, though, Scope 1 and 2 greenhouse gas emissions (own emissions) decreased by 4% year-on-year mainly due to initiatives such as continuously achieving 100% renewable energy utilization at the Matsue Data Center and procuring non-fossil fuel certificates.

Actual Greenhouse Gas Emissions

IIJ Group has expanded the scope of data collection for its greenhouse gas emissions calculation from IIJ (non-consolidated basis) to include its major subsidiaries IIJGS and IIJEG from FY2023. These companies accounted for 90% of the consolidated revenues. In Scope 1 and 2, which calculate IIJ's own emissions, the Scope 2 emissions, which recognize the electricity consumption of its own data centers, account for 97% of the total emissions. In Scope 3, which calculates indirect emissions within the upstream and downstream of supply chain, a large proportion of indirect emissions are accounted for by Category 1 "Purchased goods and services" and Category 11 "Use of sold products," which are recognized through the purchase and sale of equipment and others when providing system integration, and Category 2 "Capital goods", which is recognized through the purchase of equipment and others used in service facilities. These account for 98% of indirect emissions. In comparison with the emissions of other companies in the same industry, the emissions are generally correlated with the size of the business, and the composition of the emissions is similar for each company.
