Environmental Management

Basic Approach

The KOITO Group declares in the KOITO Group Corporate Behavior Charter, our basic policy of the corporate activities, that “guided by the theme of 'Eco-friendly Manufacturing for People and the Earth,' we will proactively engage in global environment conservation through our business activities.”
 Based on this policy, KOITO has established an Environmental Policy that sets out the framework for its environmental activities and implements that policy in the environmental management of all fields: development, design, production, procurement, logistics, and others.
 Moreover, our domestic and overseas subsidiaries also have established "Environmental Policy" as well as built environmental management systems. We are promoting environmental conservation activities throughout the KOITO Group.

Management Structure for Environmental Activities

KOITO convenes the monthly Safe and Environmental Committee chaired by the Representative Director to supervise environmental activities of the entire Group and to discuss and make decisions on important environmental issues and environmental conservation measures to be implemented under environmental laws and regulations.
 Subcommittees and working groups, such as the Energy and CO2 Reduction Subcommittee, Environmental Impact Substance Reduction Working Group, and Recycle Promotion Working Group, which were established to address specific environmental issues, are implementing specific activities.
 These activities are reported to the Safe and Environmental Committee, which follows up on progress and discussing various actions.

Establishment of Environmental Management System

The KOITO Group is building the environmental management system for the entire Group. We are working to acquire ISO 14001 and other environmental certificates primarily at our manufacturing sites. As of the end of March 2022, a total of 24 companies out of 25 eligible for certification have acquired environmental certificates: 12 in Japan, including KOITO MANUFACTURING, and 12 overseas.
 The KOITO Group also recommends major suppliers to acquire certificates, such as ISO 14001 and Eco-Action 21, in order to reinforce environmental management and conservation through the entire supply chain.

In addition, environmental impact arising from the product life cycle are also applied to the management.

Environmental Targets and Performance

To implement “Eco-friendly Manufacturing for People and the Earth” and promote environmental conservation activities effectively, KOITO has set quantitative medium-term targets and short-term targets every year for various indicators. The progress of activities is managed and the degree of achievement of targets is evaluated by the Safe and Environmental Committee and other bodies.
Environmental Management Plan and Results

Material Balance

Energy and resource inputs and emissions (outputs) of greenhouse gas (GHG) and environmental impact substances such as VOC (Volatile Organic Compounds) in KOITO's business activities are as follows.
 KOITO keeps track of the material balance in its business activities to verify and evaluate activities to reduce the environmental load and to use the data for the establishment of future measures.

Environmental Audits

KOITO conducts annual external environmental audits and internal environmental audits to check the operational status of the environmental management system. Improvement proposals are prepared and implemented to respond to the aspects identified through those audits to maintain and operate the proper management system.
External Environmental Audits
A registered external accreditation firm checks whether the environmental management system has been properly established and operated based on ISO 14001.
Internal Environmental Audits
To ensure the independence of internal environmental audits, an audit team composed of internal auditors other than the department being audited is organized, and audits are conducted based on ISO 14001. The internal auditors are also conducting audits at their departments for continuous improvements and enhance environmental awareness.

Environmental Education

KOITO has established an education system and periodically provides environmental education to promote training for human resources to achieve our environmental targets as stated in the Environmental Policy and help every employee gain a deep understanding of the environment.
 In addition to education for specific job ranks, such as new employees, managers, and supervisors, KOITO provides special education for internal auditors and promote our employees' acquisition of official licenses and qualifications. Meanwhile, June and July of every year are designated as KOITO Environmental Months during which employees participate in local clean-up activities and practice intensive environmental inspection to enhance the awareness of every employee.
 KOITO provides education on preventing contamination and spillage to workers on the premises of KOITO, such as contractors, to enhance their awareness and prevent environmental accidents.

Efforts throughout Supply Chain

KOITO is committed to promote measures to reduce environmental load based on the comprehensive perspective of the product life cycle to coexist with global environment and local communities and to engage in environmental activities through all business activities, including green procurement of raw materials, parts and equipments.
 Aiming to materialize a sustainable society, KOITO is working to strengthen supply chain management. We hold annual procurement policy briefing session and monthly information liaison meetings for suppliers to encourage them to acquire environmental certifications, such as ISO 14001 and Eco-Action 21, and request compliance with environmental laws and regulations on environmentally hazardous substances.
 In FY 2022, KOITO held a supplier meeting on May 17, 2021 and 204 suppliers attended it.
