Environmental Management

Basic approach

The Toyota Boshoku group implements environmental management activities on an on-going basis that include convening sessions for the safety, health and environmental committee in the respective regions worldwide to confirm progress on environmental initiatives, verifying cases of improvement via genchi-genbutsu (Go, see & study) and actively implementing cross-organizational deployment best practices. In addition, we are providing education to people inside and outside the organization focused on environmental protection.

Promotion system

In January 2022, we established the Carbon Neutral Environment Center directly under the President in order to further promote our carbon neutral initiatives.

Carbon Neutral Environment Promotion Committee

This is a committee for implementing the Toyota Boshoku group’s carbon neutral initiatives, setting targets and conducting follow-ups, aiming for net zero emissions.

Safety, Health and Environmental Affairs Committee (Toyota Boshoku)

This committee makes on-going efforts aimed at strengthening production environmental activities and checks the environmental activities being undertaken at each plant via genchi-genbutsu with a view to achieving the goals of the 2020 Environmental Action Plan.
As a result, all of the targets under the 2020 Environmental Action Plan were achieved.
From fiscal 2022, we are pushing forward with activities to achieve the 2025 Environmental Action Plan.

Status of activities by committee

Committees in each region promote environmental activities with the following four areas marked as priorities.

  1. Activities to ensure zero abnormalities and complaints*
  2. Activities to reduce environmental impact
  3. Activities for the management of chemical substances at plants
  4. Activities related to ISO 14001 certification

Although the environmental issues being dealt with at the state and regional level differ, the Toyota Boshoku group has set high standards for all of its activities, which can be managed and implemented by each committee.

  • Abnormalities: In case oil, etc., has leaked into a public waterway at a level that exceeds legal, by law and agreement standard values
    Complaints: In case of contact from a local citizen, government, etc., alleging physical damage or psychological effects on account of the company

Initiatives for Legal Compliance / Environmental abnormality

In order to prevent environmental accidents and pollution, we conduct environmental risk management based on voluntary standards that are stricter than regulations require. In addition, we conduct risk management with value placed on the perspective of local people. Our environmental risk map is used in this regard. An environmental risk map is a tool to visualize risk around a plant and on premises, strengthen inspection standards and enable environmental patrols.Responsible persons at each plant carefully visualize risk and conduct patrols so that the latest information is always incorporated into the risk map.
In fiscal 2021, there was one incident of a drainage abnormality*. In response, we completed the necessary countermeasures and implemented those countermeasures throughout our company in order to prevent recurrence.

  • In case oil, etc., has leaked into a public waterway at a level that exceeds legal, bylaw and agreement standard values.


All business entities in Japan completed the transition to ISO 14001:2015, the new version of the standard, in fiscal 2019. Business entities in regions outside Japan made the shift to complete the process in fiscal 2021.

ISO 14001:2015 certification activities

  • Toyota Boshoku:100%
  • Japan affiliate’s production sites:100%
  • Sites outside Japan:100%

External audits

Audits were carried out by a certification body in each country and region in a systematic manner in fiscal 2021 as well, with all plants subject to the audit evaluated as having zero non-conformance items and operating all required ISO 14001 items appropriately.

Activities to reduce emissions of chemical substances

Regarding substances which are designated as VOC*1 and PRTR,*2 the Toyota Boshoku group has reduced emissions by switching to water-based paint and by starting to transition to release agents made from components with low amounts of VOC and PRTR. Moving forward, we will continue to promote activities aimed at reducing the amount of chemical substances used and the amount of emissions from our plant.
Furthermore, the Group prohibits the use of CFCs, which are ozone-depleting substances, and does not use them.

Soil and groundwater purification at the Kariya Plant

At the Toyota Boshoku Kariya Plant, based on the “Provisional Guidelines for Soil and Groundwater” issued in 1994 by Japan’s Ministry of the Environment, we have been conducting annual inspections for soil and groundwater contamination and are working to purify these resources since 1995. Purification of soil contamination started in 1996 and was completed in 1998. Purification of groundwater contamination continues with levels maintained below standard values.

PCB treatment status

Polychlorinated biphenyls (PCBs) are now designated as prohibited substances. PCB wastes now being stored must be treated at designated treatment facilities no later than the end of March 2027.
There was no disposal of PCB wastes in fiscal 2021. In fiscal 2022, we plan to dispose of four ballasts, thereby completing the treatment of PCB waste.

Strengthening Environmental Education to Pass Environmental Conservation Activities on to Future Generations

Environmental education

In fiscal 2020, the seventh year of the project, Toyota Boshoku provided an opportunity to have fun learning about the environment by conducting on-site education at a local elementary school. On the day of the education, we introduced our environmental efforts and conducted experiments on wastewater treatment. Through group work, children deepened their understanding on the three themes of conserving energy, reducing trash, and valuing water.
(Held seven times up until fiscal 2020; not held in fiscal 2021 due to the coronavirus pandemic)

Initiatives in the local community

Toyota Boshoku holds eco-tours of our Sanage Plant sponsored by Toyota City. Parents and children living in the city of Toyota tour facilities such as wastewater treatment plants.
During the tour, we introduce the current state of worldwide water shortages worldwide. Participants also take part in experiments introducing the wastewater treatment process and water quality analysis method at Toyota Boshoku. It is an outstanding opportunity for conveying the importance of water.
We will continue to deepen our understanding of the environment and aim for a sustainable global environment together with members of the local community.
(Held twice up until fiscal 2020; not held in fiscal 2021 due to the coronavirus pandemic)
