Environmental Data Energy consumption and CO2 emissions
The OKI Group is actively working to improve the efficiency of energy use and reduce CO2 emissions in its business activities at its sites.
Achievements in Fiscal 2023
The OKI Group's business sites are promoting decarbonization efforts by improving efficiency (energy saving) and introducing renewable energy.
As specific examples of our efforts, over the years we have promoted energy conservation by improving the efficiency of facilities such as air conditioners and lighting (facilities attached to buildings) and production facilities, improving the operation of these facilities, and improving the efficiency of operations.
In recent years, we have also been advancing the introduction of renewable energy. In July 2022, we began full-scale operations at our Honjo Plant, which received Japan's first "ZEB"* certification.
Starting in fiscal year 2023, we purchased non-fossil fuel certificates, and in April 2024, we installed solar panels at OKI Nextech's Komoro Plant. In fiscal year 2023, we exceeded our CO2 reduction targets. Moving forward, we will continue to enhance our renewable energy initiatives and promote decarbonization alongside our existing energy-saving measures.
In addition, OKI Engineering, which develops reliability assessment and environmental conservation technical services in the OKI Group, began introducing renewable energy in fiscal 2022 with the aim of realizing a "Carbon Neutral Laboratory" by reducing CO2 emissions from the use of electricity at all 5 sites in fiscal 2025. As a result, they aim to reduce CO2 emissions generated by their contracted test and evaluation services to 0, thereby contributing to the reduction of CO2 emissions in their customers' supply chains.
- *ZEB (Net Zero Energy Building) : A building that aims to achieve a net zero balance of primary energy consumption through the use of renewable energy sources and energy conservation measures, such as highly insulated structures and sensors, while maintaining a comfortable indoor environment. Energy consumption from production facilities, office equipment, etc., is excluded from the ZEB calculation.
