Kokuyo Co., Ltd. (Headquarters: Osaka City / President: Hidekuni Kuroda) announced that it has introduced electricity derived from renewable energy (hereinafter, 'RE') at its Tokyo Shinagawa office, THE CAMPUS, starting April 24, 2026.
Kokuyo Tokyo Shinagawa Office 'THE CAMPUS'
At Kokuyo, we have set 'Activities to protect the Earth, the foundation of WORK & LIFE' as a strategic theme of our materiality, and we are working to reduce greenhouse gas emissions under the materiality 'Response to the Climate Crisis.' To decarbonize electricity, which is the largest energy source within Scope 1 and 2, we have been promoting the switch to RE power at our own factories in Mie, Shiga, Chiba, and Tottori prefectures.
In this initiative, we will partially introduce geothermal and solar-derived RE electricity provided by JERA Cross Corporation (hereinafter, JERA Cross) at our Tokyo Shinagawa office 'THE CAMPUS,' which operates as a laboratory for 'working, learning, and living.' The introduction of geothermal-derived RE electricity at 'THE CAMPUS' is the first for the Kokuyo Group, which will enable stable RE power supply even at night when solar-derived electricity supply is interrupted.
JERA Cross, as an aggregator, will supply 'THE CAMPUS' with geothermal-derived electricity procured from Kyuden Mirai Energy Co., Inc., combined with electricity from multiple off-site solar power plants. The annual renewable energy supply is estimated to be approximately 375,000 kWh, and the estimated reduction effect from this scheme is approximately 159 t-CO₂ per year (*1).

Kokuyo will continue to promote various initiatives to contribute to the decarbonization of society.

・Kokuyo's Environmental Initiatives
Over 90% of the CO2 emitted by the Kokuyo Group is Scope 3 (emissions in the supply chain). Therefore, in addition to reducing its own emissions, Kokuyo is working to contribute to the decarbonization of society by collaborating with production and distribution partners throughout the entire supply chain, including reviewing raw materials and devising delivery methods.

・JERA Cross Corporation
JERA Cross Corporation provides comprehensive decarbonization solutions, including renewable energy introduction support, power aggregation, and 24/7 carbon-free power (*2) supply, as a one-stop partner for companies achieving GX. Its parent company, JERA Co., Inc., aims to achieve virtually zero CO2 emissions from its operations by 2050 through renewable energy and zero-emission thermal power, under its 'JERA Zero Emission 2050' vision.

[Appendix]
(*1) Basis for calculation of 'Estimated reduction amount: approximately 159 t-CO₂/year': Estimated power generation 375,386 kWh × National average emission factor (FY2024) 0.000423 t-CO₂/kWh
(*2) '24/7 (twenty-four seven) carbon-free power' refers to electricity that emits no CO2 24 hours a day, 7 days a week, i.e., 365 days a year. In accordance with the Ministry of Economy, Trade and Industry's 'Guidelines on Retail Electricity Sales,' it means providing 100% of demand power with a power source composition of CO2 zero-emission power sources (meaning renewable energy generation facilities, hydrogen generation facilities, etc.) and environmental value through the use of non-fossil certificates. It does not mean that CO2 is not emitted throughout the entire lifecycle, including fuel production and transportation.
