Promotion System

Our group has established a Central Environmental Committee (with regular meetings twice a year and extraordinary meetings as necessary), chaired by an officer appointed by the Chief Environmental Officer (President), to ensure compliance with environmental laws and regulations and to promote environmental protection. The Central Environmental Committee checks the progress of Eco Vision 2030 and our group's environment-related issues in order to ensure continuous improvement. Important decisions made by the committee are reported to the Board of Directors through the Management Meeting.

In FY2025, the Central Environmental Committee held two meetings to report on and discuss the progress of Eco Vision 2030, Promoting Group Governance, information on environmental accidents, and the progress and future plans of the roadmap for addressing climate change.
In order to achieve Eco Vision 2030, Each internal company is expected to manage its own targets on items relevant to business activities. Meanwhile, we take the initiatives to such activities as compliance of regulations, raising environmental awareness, and communication with local society mainly on the regional basis in accordance with action plans. In addition, various working groups are set up as the cross-functional team across the internal company to address specialized issues such as carbon neutrality, energy conservation and chemical substances.

Initiatives for Environmental Risk

Our group identifies risks in its business activities, such as environmental incidents and pollution, and endeavors to reduce and prevent them. We promote voluntary initiatives that go beyond mere legal compliance. In cases where regulatory limits exist under laws, regulations, and agreements with local municipalities regarding air quality, water quality, noise and vibration, we have established voluntary standards that are stricter than these limits and regularly monitor and manage them. In the event of any deviation from these standards, we promptly act and strive to ensure thorough recurrence prevention.

Dust Dispersion Prevention Measures

In the manufacturing process, local exhaust ventilation systems are installed at dust generation sources to ensure reliable suction and collection. Collected dust is passed through high-performance dust collection equipment to minimize emissions into the atmosphere. Furthermore, to ensure these systems always function properly, we conduct thorough periodic filter replacements, inspections, and cleaning, striving to preserve the surrounding environment.

Management of Wastewater Discharge

Regarding factory wastewater, it is discharged after being treated by the wastewater treatment facilities at each site. We manage this process using voluntary standards that are stricter than legal regulatory limits to prevent the release of pollutants into the environment.

Noise and Vibration Countermeasures

We install soundproof covers and other equipment on noise-generating facilities to ensure that noise does not diffuse.

Drills for Emergency Situations

Soil and groundwater investigation and response

Our group conducts necessary surveys in accordance with the Soil Contamination Countermeasures Law. In addition, as part of its environmental management, our group has been conducting voluntary surveys of groundwater contamination at its plant site boundaries on a regular basis since FY2022. In the event that hazardous substances exceeding the standards of the Soil Contamination Countermeasures Law are detected, we promptly report the matter to the administrative authorities and implement appropriate measures in accordance with their guidance.
Information is also disclosed on the news site of our website.

PCB Control

Within our Group in Japan, we properly manage and systematically dispose of PCB-containing equipment and waste in accordance with the Act on Special Measures concerning Promotion of Proper Treatment of Polychlorinated Biphenyl Wastes (PCB Special Measures Act). For high-concentration PCBs, we identified target equipment through surveys conducted in the past and completed the disposal of all such equipment by the statutory deadlines stipulated by laws and regulations. For low-concentration PCBs, equipment identified in past surveys has also been disposed of sequentially according to plan. Even if equipment containing low-concentration PCBs is newly detected due to equipment decommissioning or replacement, we have established and maintain an internal system and operational workflow to complete its disposal within the fiscal year in which it is discovered.

Compliance with Environmental Laws Regulations, and Other Requirements

Handling Violations and Complaints in Fiscal 2025

In FY2025, there were two violations (one of which exceeded the limit set in the agreement with the city), no accident and one complaint. We promptly took action to address the violations and complaints to prevent recurrence.
