Sustainability Management

Sustainability Management Promotion Framework

Twice a year (in May and November), we hold a CSR Council where our President serves as a chairperson, as part of an organizational framework that was set up to discuss and develop plans for addressing the social responsibility issues that Yokohama Rubber Group is currently facing.
Organizations including the CSR Council, the Corporate Compliance Committee, the Environment Council, the Central Labor Relations Committee, the Central Safety and Health Committee, and the Risk Management Committee have been established, with the responsible officers serving as chairpersons to deliberate on various issues.
Matters with a material impact on management are submitted to the Management Meeting for approval.
We have three task forces, two sub-councils, and four committees that promote environmental activities as sub-bodies within the Environmental Council. The Environmental Council engages in business activities as a product development framework and continues to provide environmentally friendly products.
In addition, with the aim of implementing high quality and homogeneous sustainability management at all of our bases around the world, we are promoting area management of internal controls, including the environment and compliance, under the control of the regional management company.
In fiscal year 2023, we implemented training on the grievance handling system in Indonesia starting in November.

Enforcement of
Environmental Training and Education

CSR and Environmental Training

We have incorporated CSR and environmental training as one of the subjects to be studied by recent graduate hires and mid-career hires. In addition, a career development course, "CSR and Environmental Knowledge," was held for employees in their second to third year of employment in personnel training for career-track positions.
In addition to learning about the environment in general, education on biodiversity conservation including a river monitoring experience was provided. In fiscal year 2023, training sessions were primarily conducted in person, with some online participation offered in the second half of the year to accommodate employees working in remote locations. A total of 65 employees participated in these sessions across both semesters. Additionally, we offered a "CSR (Intermediate Level)" career development course for employees with approximately 10 years of experience. This online course covered topics such as SDGs, ESG investing, and CSR challenges related to the environment, safety and health, disaster preparedness, and business continuity planning (BCP). Forty employees participated in this course. These career development courses are mandatory for promotion. To date, 928 employees have participated in CSR training, representing 17% of Yokohama Rubber's workforce.
In addition, in order to ensure that our managerial and supervisor level employees thoroughly understand ISO14001, we are conducting training classes for environmental internal auditors. Including 92 personnel who have completed this course to get certified in fiscal 2023, currently a total of 2,460 personnel have been registered and are already active as our internal auditors. (47% are qualified internal auditors in the scope of the integrated certification.)

Enhancement of Education Activities

As part of our environmental education activities, we conduct improvement activities by getting involved with all our personnel by sending our President’s message to all our employees in the Energy Saving Month in February and the Environment Month in June every year. For our Environment Month from June 1 to 30, we accept suggestions for environmental month slogans and posters from all Yokohama Rubber Group employees and family members up to elementary school student age.
In fiscal year 2023, we received 6,266 eco-declarations and 114 posters from domestic participants, while international participants submitted 5,402 eco-declarations and 640 posters.

Environmental Slogan Best Work

I will learn the names of wild birds. Birdwatching will help me increase my awareness of environmental protection.
Mr. Yoshikatsu Tase, Product Planning Group, OHT Business Planning Department

To combat fast fashion and reduce textile waste, I pledge the following:
1. I will always think before I buy clothes. I will never buy anything I plan to wear only once and then discard.
2. Instead of throwing away clothes I no longer wear, I will pass them on to family members or friends.
While my individual actions may not seem like much, every small step towards reducing textile waste makes a difference. By making these changes, I am contributing to a more sustainable future.
