Approach by Businesses Toward Environmental Conservation Cross-departmental environmental management activities tailored to site characteristics
The OKI Group promotes activities from comprehensive and individual perspectives.
Decarbonization Initiatives at Business Sites
The OKI Group's business sites are promoting decarbonization efforts by improving efficiency (energy saving) and introducing renewable energy.
Improving efficiency (energy saving)
Our main focus is to improve the operation of on-site facilities and upgrade facilities to higher efficiency, with a target of 1% or more per unit of energy consumption.

Introduction of Renewable Energy
The OKI Group is promoting a balanced approach to introducing renewable energy, such as adopting solar power generation at business sites and purchasing renewable energy certificates. In fiscal year 2023, we exceeded our CO2 reduction targets. Moving forward, we will continue to enhance our strategies for implementing renewable energy and drive decarbonization alongside our traditional energy-saving measures.
| Renewable energy cases | In July 2022, the Honjo Plant, which received Japan’s first ZEB(*) certification, began full-scale operations. In fiscal year 2023, non-fossil certificates were purchased, and in April 2024, solar panels were installed at OKI Nextech’s Komoro Plant. |

| OKI Engineering, which provides reliability evaluation and environmental protection technology services within the OKI Group, aims to achieve zero CO2 emissions from electricity usage at all five of its sites by fiscal year 2025, realizing a "Carbon Neutral Test Lab." Since fiscal year 2022, OKI Engineering has been advancing the implementation of renewable energy. This initiative aims to eliminate CO2 emissions generated by its contracted testing and evaluation services, contributing to reducing CO2 emissions in the customer supply chain. |
- *ZEB (Net Zero Energy Building): A building that aims to reduce the balance of primary energy consumed by the building to zero by creating energy from renewable energy sources and conserving energy through the use of highly insulated structures and sensors, while also realizing a comfortable indoor environment. (Energy consumption by production facilities, office equipment, etc. is excluded from the calculation of ZEB.)
Environmental Measures According to Site Characteristics
Environmental measures at each site are promoted according to their characteristics. For example, decarbonization activities are classified into processing plants mainly for painting and plating, assembly plants for component packaging, large-scale offices, and small-scale offices, and measures are promoted according to their characteristics.
As an example, processing plants are characterized by continuous operation of production facilities and air conditioning equipment. For these we are primarily working to achieve a fixed reduction in energy consumption. The assembly plant has the characteristic of a low fixed load and energy consumption that fluctuate according to production volume. Based on the fact that high-mix low-volume production is increasing, efficiency is being promoted through measures such as cell production, unit production, and change in layout. In our large offices, we are promoting improvements through the introduction of energy-efficient air conditioning equipment and lighting fixtures, and in smaller offices we are making improvements centered on energy conservation activities and other operational aspects.
The OKI Group aims for optimization across the entire Group by implementing such measures and setting targets according to site characteristics, conducting trials for common issues, and horizontally developing effective cases to other sites.
