Chemical substance
Harmony with nature,
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.
In FY2020, due to the impact of COVID-19, the conservation activities were carried out only to the extent possible in order to prevent the spread of infection.

Control and reduction of substances
of concern contained in products

Establishment of the Product and Environment Committee

The Product and Environment Committee has been established among the related departments as part of JTEKT’s initiatives to recognize and manage the substances of concern contained in our products. This committee promotes the activities by working groups which are in charge of collecting information, managing data, and holding in-house training programs and so on, by arranging Section Meetings.

Major FY2020 results

Initiatives of the Product and Environment Committee’s Supplier Working Group

JTEKT has established the seven working groups under the control of the Product and Environment Committee. These working groups engage in activities aiming at accurate data management from obtaining to reporting processes.
In FY2020, the Supplier Working Group conducted the survey for the purpose of grasping the management systems for chemical substances contained in products from all the suppliers. Moreover, in FY2020, in order to understand the management systems for rubber resin, electrical components and other products for which the management of chemical substances is important, JTEKT conducted remote audits of the management systems of 12 companies and provided continued guidance for their issues to promote further improvement.

Reduction of substances of concern
in production activities

Reduction of substances regulated by PRTR

JTEKT is taking actions to manage and reduce the chemical substances released into the environment from production activities.
JTEKT made an amended report retroactively due to an error that was discovered in the report of emissions and transfers of substances regulated by PRTR for FY2019 in the administrative report in FY2020. The error was caused by calculations based on incorrect component information for some of the chemical substances. From now on, to properly manage the substances regulated by PRTR, JTEKT will strive to improve management accuracy by regularly reviewing the component information of registered products for errors or changes.
In FY2020, JTEKT’s emissions and transfers of substances regulated by PRTR was approximately 33.5 t, reduced by approximately 8.8 t compared to the previous year. Of the substances regulated by PRTR, VOC emissions were approximately 30.3 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.

Proper storage and control of PCB devices

The Act on Special Measures concerning Promotion of Proper Treatment of PCB Wastes requires the storage, disposal, and notification of PCB (polychlorinated biphenyl), widely used as insulating oil. At JTEKT, PCB is reported, properly stored, and disposed of in accordance with this act. Since the disposal deadline was reached at the end of March 2021 for regions carrying out disposals at JESCO Kitakyushu, in FY2020, JTEKT conducted a re-investigation to find out if there were any remaining PCB equipment not only at production sites but also sales sites, welfare facilities, and all other buildings liable to have remaining PCB equipment.
As a result, a total of 1,019 lighting ballasts were discovered and disposed of by the end of March 2021.
From FY2008 to FY2021, JTEKT disposed of 256 high-concentration PCB transformers and capacitors and 6,406 high-concentration PCB lighting ballasts, completing disposal of all high-concentration PCB-emitting wastes owned by JTEKT.
From now on, in accordance with the act, JTEKT will report, properly store, and dispose of wastes that are also found to contain small amounts of PCB.

Measures for soil and groundwater

Since 1998, JTEKT’s Kariya and Okazaki plants have been implementing ongoing measures to prevent external leaks and to purify groundwater of trichloroethylene, a substance previously used in detergents and other materials. We do this by using a pumping and aeration system (*1).
In 2020, the Okazaki Plant implemented an effective microbial purification system (*2) in which nutrients are injected as part of the measures for achieving complete purification. From FY2021, JTEKT will continue to monitor progress and strive for complete purification.
JTEKT reports the assessment results about groundwater to government agencies and provides local residents with explanations at community meetings.

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

*2 Microbial purification system: A method of restoring contaminated environments by utilizing microbial function. The purification capability of microbes living in the environment is enhanced by injection of nutrients, etc.

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. To update air conditioners using R22 , which is an HCFC refrigerant, JTEKT confirmed the use of air conditioners using R22 in FY2020. By 2025, JTEKT will discontinue use of air conditioners using R22 to contribute to ozone layer protection and CO2 reduction.

Initiatives for biodiversity

Biodiversity Conservation Action Guideline

In order to reduce the environmental burden created by our business activities and bemindful of biodiversity, JTEKT established the Biodiversity Conservation Action Guidelines in March 2011 based on the Environmental Action Plan 2015 of our JTEKT Group Environmental Vision.
Biodiversity Conservation Action Guideline

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 surround- ing each plant and 3) developing environmentally-minded profes- sionals in order to achieving 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

In the life cycle of business activities that begins with the procurement of raw materials, JTEKT and biodiversity are mutually affected as JTEKT faces risks including water and energy resource consumption and emissions into the atmosphere and water areas. JTEKT also has opportunities to mitigate climate change by providing products such as vehicles with improved environmental performance to reduce CO2 emissions and reduce flood risks at business locations by conserving water resources through forest conservation activities.

Impact on biodiversity

The environment on which we continue to live in abundance is based on the maintenance of biodiversity. To conserve biodiversity and protect sustainable use, in the business activity life cycle that starts with the procurement of raw materials, JTEKT endeavors to understand the direct and indirect impact on biodiversity, such as use of resources including water and energy, release into the atmosphere and bodies of water, and reduction of CO2 emissions through the provision of products and promotes activities that have a positive impact on natural capital.

Map of JTEKT biodiversity conservation activities

Business locations in both Japan and overseas of JTEKT and the JTEKT group endeavor to promote biodiversity conservation initiatives by connecting the activities of individual plants.
Each business location has established activity themes as it carries out the activities.
JTEKT will continue to promote the initiatives in order to expand the circle of activities.

Appreciation Letter from Tokushima Prefecture
In Tokushima prefecture, where the JTEKT Shikoku Plant is located, to demonstrate the public interest function of forests, such as securing high-quality water resources and absorbing carbon dioxide and to pass on the rich forest of Tokushima to the next generation, the Tokushima Collaborative Forest-Building Project has been carried out since 2009, and in 2011, JTEKT entered into a partnership agreement with Tokushima prefecture and the National Land Afforestation Promotion Organization in Tokushima to carry out forest-planting activities. This project is a model implementation of the carbon offset mechanism that compensates for the portion of CO2 emitted from companies and ordinary households that cannot be reduced by itself by absorption through forest maintenance such as thinning and tree planting. For its many years of contribution, JTEKT received a letter of appreciation from Tokushima prefecture. Through these activities for symbiosis with nature, JTEKT will continue to contribute to the achievement of a sustainable society together with the local community.

Major initiatives – Overseas case

Greening Activity through Tree-Planting
