Sustainability Management

Sustainability Management Promotion Framework

The CSR Council, chaired by our Chairman & CEO and membered by all of the internal directors (including Audit and Supervisory Committee members), meets twice a year (in May and November) to discuss sustainability issues (environment, occupational health and safety, disaster prevention, quality, human capital, human rights, and social contribution, etc.) and plan actions to be taken by the Yokohama Rubber Group.
In addition, in the case that it is necessary to make decisions
on important matters or make early decisions, or make reports or conduct deliberations, an Executive Committee will make reports and conduct deliberations, and submit the details of such reports and deliberations to the Board of Directors according to their importance.
For individual sustainability issues, we have established bodies such as the Environment Council, the Central Safety and Health Committee, and the Central Meeting for Disaster Prevention to formulate and implement more detailed plans and measures.
Progress on sustainability issues is reported monthly to the Chairman & CEO, President & COO, members of the board in charge of CSR Division, and internal directors serving as Audit and Supervisory Committee members.
In addition, at biannual meetings where all Group executives, including those overseas, gather to discuss business strategies and other matters, initiatives on carbon neutrality and the circular economy are discussed as ongoing themes. For serious and urgent sustainability issues, we respond in cooperation with the “Risk Management Committee.”
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 2024, we completed the implementation of the “Global Whistleblowing System” in Indonesia.

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 2024, 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 69 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). 67 employees participated in this course. These career development courses are mandatory for promotion.
To date, 1,064 employees have participated in CSR training, representing 19% 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 70 personnel who have completed this course to get certified in fiscal 2024, currently a total of 2,741 personnel have been registered and are already active as our internal auditors. (47.6% 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 2024, we received 5,533 eco-declarations and 123 posters from domestic participants, while international participants submitted 4,831 eco-declarations and 749 posters.
