Harmony with nature, Biodiversity

Thorough management of chemical substances and reduction of substances of concern

The regulations to administrate the usage and discharge of substances of concern which have adverse impact on ecosystems and human health are being strengthened. Additionally, companies are required to implement measures to thoroughly manage and reduce the substances of concern throughout the entire product lifecycle, from production to disposal, and comply with various related regulations.
As a MONOZUKURI (manufacturing) company, it is a social responsibility to reduce the substances of concern. JTEKT not only reduces the amount of substances used and discharged during production, but also identifies and thoroughly manages the substances of concern contained in its products.

Biodiversity conservation

The diversity of living things on Earth is rapidly disappearing due to the shrinking of habitats from the expanded destruction of nature, and "preventing the loss of biodiversity" is one of the SDGs goals. Corporate activities depend on the benefits we receive from the natural world, and at the same time, they have a significant impact on biodiversity. This is why it is important that companies are proactively involved in biodiversity conservation activities such as protecting the natural habitat. In JTEKT's Biodiversity Conservation Action Guidelines (formulated in March 2011), JTEKT positions biodiversity conservation as an important social issue supporting lives and livelihoods, and is expanding the circle of activities related to biodiversity by promoting initiatives at each plant that make the most of local characteristics.

Reforming the Product and Environment Committee

The Product and Environment Committee was established to strengthen the management of chemical substances contained in products. It works in collaboration with seven working groups with different roles, and conducts activities on a global basis, including the collection of regulatory information on substances of concern, policy development, determination of alternatives, switching of products, and internal and external education and auditing.

Product and Environment Committee

Major FY2022 results

Major initiatives in the Education and Audit WG

The Education and Audit WG promoted the following activities on a global basis with the aim of fostering awareness and a climate.

  • The contents of the check sheet have been reviewed with the aim of strengthening internal audits, and the expansion of the coverage is under consideration for the next fiscal year.
  • In addition to in-house lectures, e-learning education is launched during Environment Month, which is held every June.
  • Subject extraction and countermeasures have started by analyzing the results of in-house lectures and environmental month e-learning comprehension tests and questionnaires.
  • Sharing what was learned in the external lectures with members participating in the Product and Environment Committee
  • Roles and rules for the preparation of past troubles collection are reviewed and published on a regular basis.
  • Regular publication of Basic Learning
  • A three-minute video on the importance of managing chemical substances in products was created and published on the company website

We will continue to change the way our Product and Environment Committee works and promote various reforms so that we can steadily do what we can't do now, based on the criteria of "for the earth, for the world, for our customers and for the next generation."

Reduction of substances of concern in production activities

In FY2022, JTEKT's emissions and transfers of substances regulated by PRTR was approximately 31.1 t, reduced by approximately 1.1t compared to the previous year.
Of the substances regulated by PRTR, VOC emissions were approximately 27.6 t, and xylene 1, 2, 4-trimethylbenzene used in the painting process accounted for the majority. To further pursue reduction in use, we will work to completely eliminate the use of kerosene in the production process in accordance with the Environmental Action Plan 2025.

Initiative to completely eliminate the use of kerosene for purposes other than fuel use

JTEKT is working to completely eliminate the use of kerosene for purposes other than fuel use by FY2025 in order to reduce hazardous substances and risks pertaining to safety and fire prevention.
In FY2022, JTEKT started long-term operational tests on production lines using alternative oils and it has already been partially switched over .We will continue the initiative for the complete elimination.

Proper storage and control of PCB devices

PCB (polychlorinated biphenyl), which were widely used in insulating oils, must be stored, disposed of, and reported according to the Act on Special Measures concerning Promotion of Proper Treatment of PCB Wastes. At JTEKT, PCB is notified to the authorities, properly stored, and disposed of in accordance with this act.
In FY2022, JTEKT disposed of equipment that had been stored as low-concentration PCB waste. In FY2023, we are continuing to identify equipment that may contain low concentration PCB and carry out appropriate treatment after PCB analysis.

Initiatives for soil and groundwater

JTEKT continues to implement ongoing measures at two plants in response to the groundwater pollution caused by trichloroethylene contained in detergents and other materials.
The Kariya Plant is implementing the "prevention of external leaks", and the Okazaki Plant is implementing "complete purification" in addition to the "prevention of external leaks".
To prevent leaks outside the plant premises, we have continually been using the pumping and aeration system (*1) since 1998.
As part of a complete purification, nutrients were injected into the ground in 2020 to enhance the activity of microorganisms that decompose chloroethylene. We are continuing to monitor its progress, as a certain degree of effectiveness was seen from this measure.
JTEKT regularly reports the assessment results of groundwater measurements to government agencies and provides local residents with explanations at community meetings.

*1 Pumping and aeration system: A system of pumping groundwater up and sprayeding, and blowing air from below to aerate and separate organic solvents to be removed by adhering to activated carbon.

Measured trichloroethylene value (maximum)

FY2021 FY2022 Current status
Kariya Plant 0.629mg/L 0.313mg/L Purifying
Okazaki Plant 0.004mg/L 0.008mg/L Purifying

(Environmental standard: 0.01 mg/L)

Initiatives to replace CFC devices

Production of HCFC refrigerants has been discontinued since 2020 in accordance with the Montreal Protocol and Ozone Layer Protection Act. JTEKT is gradually updating our R22 air conditioners. By 2025, JTEKT will discontinue use of air conditioners using R22 to contribute to ozone layer protection and CO2 reduction.

Initiatives for biodiversity

JTEKT's aspiration

JTEKT's biodiversity conservation activities focus on the three main initiatives of 1) protecting the rare living species that inhabit or grow at each plant, 2) enhancing the local natural environments surrounding each plant and 3) developing environmentally-minded professionals in order to achieve conservation of biodiversity on an ongoing basis. We engage in activities to protect the rare living species at each plant based on objective evaluations incorporating the viewpoints of experts and academics.

Biodiversity risks and opportunities in business activities

JTEKT's business activities and natural capital are influenced by each other. In the life cycle of our business activities, which begins with the procurement of raw materials, we see the use of resources such as water and energy, as well as emissions into the air and water as risks. We also see these as opportunities for biodiversity, such as mitigating climate change by reducing CO2 emissions through the provision of products that improve the environmental performance of vehicles, etc., and maintaining the function of recharging water sources through forest conservation activities, which leads to a reduction in the risk of flood damage at the site of our business.

Impact on biodiversity

We conducted pressure assessments on biodiversity using the WWF Biodiversity Risk Filter (BRF)* targeting all JTEKT Group sites and the sites of 40 major Japan suppliers (equivalent to 70% of the procurement amount). As a result, none of the sites were rated as high risk (4.5 or higher on a scale of 1 to 5).
We will continue to promote activities to the maximum extent possible so that our business activities do not have an impact on biodiversity due to emissions into the air and waters or soil pollution.

Major initiatives

Iga Proving Ground Arbor Day

In July 2017, the Iga Proving Ground signed the "Forest for Social Contribution" (* 1) agreement with the Mie Forest Management Office. The "JTEKT Iga Proving Ground Natural Symbiosis Forest" covers approximately 25.4 hectares in the national forest surrounding the proving ground.
Arbor Day was held again in FY2022. Under the guidance of a local NPO, the Nishiyama Hometown Preservation Society, members of the Iga Proving Ground and the Kameyama Plant planted cherry, maple and other trees. We plan to continue our tree-planting activities in the future and develop the forest so that the local community can enjoy walking and other activities.
