Our Group has introduced an Environmental Management System to systematically and effectively promote environmental conservation activities. Through this system, we ensure continuous improvement of environmental performance and compliance with laws and regulations, addressing specific environmental challenges, including the transition to a decarbonized society and a circular economy.

Environmental Management Organization

Our Group has obtained third-party certification for Environmental Management Systems (ISO 14001) globally. Through this, we comply with environmental laws and regulations in each country and aim for continuous improvement of environmental performance. In Japan, we have obtained certification using the multi-site method (Taira Forging Co., Ltd. has obtained certification independently), and under the top management of the Executive Officer in charge, all business sites work together to achieve environmental targets.
In addition, the Company-wide Environmental Management Committee meets quarterly to confirm the progress of our environmental policies and targets, and to discuss improvement measures.

ISO 14001 Certification and Registration

In principle, our business sites acquire certification for Environmental Management Systems (ISO 14001) within three years of operation, and all existing business sites globally have acquired certification. New business sites will gradually acquire certification in accordance with the above principle. In Japan, we acquire certification using the multi-site method (Taira Forging Co., Ltd. has obtained certification independently). Overseas, certification is acquired at each business site.

Global Response to Environmental Laws and Regulations

The NTN Group considers compliance with environmental laws and regulations in each country and region as a corporate responsibility, and we are taking reliable measures. In addition to the standards set by laws and regulations, we are also advancing initiatives from our own unique perspective, and the following are examples of these efforts.

■Regional Approaches to Environmental Laws and Regulations

Region	Initiative
Japan	Based on domestic environmental laws and regulations, we conduct regular audits and reporting, and strive to reduce environmental impact.
Europe	We comply with European environmental regulations, strictly adhering to regulations particularly regarding chemical substance management and waste treatment.
Americas	We respond to environmental laws and regulations in the United States, Canada, and Latin America, promoting both effective resource utilization and emission reduction.
Asia-Oceania	Even in Asia’s emerging markets, we comply with local environmental laws and regulations and strengthen cooperation with local communities.

Our Group conducts environmental education according to hierarchy and function with the aim of improving environmental awareness among all employees. Furthermore, we work on solving environmental issues and improving regional environmental value through the utilization of IT and collaboration with local communities.

■Educational and Activity Initiatives for Raising Environmental Awareness

Education Category	Target and Content	Implementation Method and Features
Education by Job Level	New employees: Basic education in induction training and practical education after assignment Newly promoted managers: Learn environmental issue responses from a risk and benefit management perspective in promotion training	Group training and on-the-job training (OJT) format
Training by Job Functions	Sales departments and dealerships: Handle investigation responses regarding environmentally hazardous substances in products and understand related law Environmental management departments: Internal auditor training	Specialized training and compliance training
All Employees	Disseminate important measures during Environment Month (June) and host events	Internal events, poster displays, etc.
IT Utilization	Introduction of online training and e-learning	Used in combination with group training to provide flexible learning environments
Regional Cooperation	Promoting participation in regional environmental events and volunteer activities	Environmental conservation through co-creation with local communities

Raising Environmental Awareness

The domestic Group distributes “Environmental Policy Cards” to all employees (including personnel working at business sites such as resident contractors, temporary staff, and subcontractors) to raise environmental awareness. Additionally, during Environment Month in June each year, we: (1) conduct environmental education, (2) conduct environmental patrols, (3) publish environmental news, and (4) display the Environment Month poster issued by the Ministry of the Environment. As an example, OKAYAMA WORKS published an “Environment Monthly News” to deepen understanding of the importance of waste treatment.

The NTN Group has established a company-wide emergency response system to ensure rapid and appropriate responses during emergencies. At each business site, we work to improve employee response capabilities through regular drills and education, and implement measures to minimize environmental impact.

Emergency Response Drill

Oil Leakage Response Drills at NTN FUKUROI CORP.

At NTN FUKUROI CORP. (Fukuroi City, Shizuoka Prefecture), a total of six emergency response drills, including drills involving the use of portable water pumps and the startup of emergency generators, were conducted in FY2025 to improve the site’s ability to respond to environmental risks such as oil leaks.
During the drills, in addition to preparing, operating, and discharging water using portable pumps, starting up the emergency power generator, and checking the drainage system and the risk of external outflow, participants practiced responding to oil leakage using oil fences, oil-absorbent mats, and water-filled containment barriers, confirming initial response procedures aimed at preventing the spread of any spill.
In addition, through the drills, participants worked to master equipment operating procedures and provide education to first-time participants, while also improving their ability to respond to oil leakage incidents.
The NTN Group will continue to work on improving its ability to respond to environmental risks and reducing environmental impact through ongoing drills and education at each business site.

Horizontal Expansion Within the Group	We share lessons learned from incidents throughout the Group to prevent similar incidents.

In order to efficiently promote environmental conservation, the NTN Group in Japan quantifies the costs and economic benefits of environmental conservation by classifying them based on guidelines drawn up by the Ministry of the Environment. Environmental conservation costs for FY2025 were approximately 3.16 billion yen, including research and development of eco-friendly products, and the economic benefits of environmental conservation measures were approximately 2.111 billion yen.
