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 2022, an environmental conference was held in the China area, and education on the introduction of a complaint handling system was conducted in Thailand and other countries.

Management System

Enforcement of Global Environmental Management Based on ISO14001

We aim to maintain high-quality environmental management under the same standard both in domestic and overseas group companies; thereby we have positioned ISO14001, which is the international Environmental Management System standard, as the basis of our management.
We are trying to get all our operation sites to obtain ISO14001; so far, a total of 16 operation sites in Japan, comprising eight from Yokohama Rubber and eight from our group for domestic operations have obtained it, whereas overseas a total of 30 operation sites of 16 group companies have been certified. (The ISO 14001 certification rate for production sites is 100%.)
It should be noted that during fiscal 2012, ISO14001 integrated certification was acquired for the integrated environmental management of Yokohama Rubber’s ten production bases and the head office, and a total of 16 Yokohama Rubber and Group company offices acquired ISO14001:2015 integrated certification in 2018. This reflects the high level of homogenization.
In addition, our non-manufacturing sites are promoting environment management in accordance with the ‘CSR Environmental Management Guidelines’ and our approach to the environment.
The Yokohama Rubber head office and systems company in Japan and Group distribution subsidiaries in Australia and Taiwan have acquired ISO14001 certification, under which they are further advancing their environmental management.
Our tire production facility in Thailand has also acquired ISO 50001 certification for its energy management system.

As of March 2023

Execution of Comprehensive Environmental Audit

We are conducting audits as to continual progression for improvement on the management system of environmental management, improvement on the environmental performance, and minimizing environmental risks per operation unit by conducting internal audits of business locations as a first-party audit, integrated internal audits by the Environmental Protection Promotion Department, and an external audit as a third-party audit every year (all audits are based on ISO14001).
Also, our Environmental Protection Promotion Department is checking and verifying the score of self-evaluation at each business site in accordance with CSR Environmental Management Guidelines for domestic distribution companies within our group.
There were no indications of any violation of environmental legislation among all the auditing items in fiscal 2022.

Internal Audit

Overseas production sites have acquired and implemented ISO14001 certification.
Through our internal audit, we work to continually improve the level of our environmental management system. We conducted our audit not just to operate and maintain our environmental management system, but also by setting our common themes as whether our system is duly functioning for our purposes, whether each member of our group is walking the talk by reviewing and setting up the guidelines, purposes, and target by shifting more focus on the reduction of environmental burden in an even more proactive manner during their normal business activities.

Integrated internal audit

Integrated certification has been acquired for production sites in Japan. In order to make overall improvements to environmental management and work towards the cross deployment of key issues, internal audits are also conducted by members from each site.
In fiscal 2022, we conducted internal audits based on the positioning for fiscal 2015, and we worked to improve the level of chemical substance control and response to environmental risks, focusing in particular on our production and development sites.
Also, we focused on the promotion of various activities to contribute to society from the perspective of CSR and the level of communication with stakeholders, including local residents, in the audit.

External Audit

During fiscal 2022, an integrated EMS certification registration audit was continued by an ISO audit registration organization that covered all of the group’s Japanese production bases and its Headquarters, and as a result we successfully completed a periodic review ISO14001:2015.
While no nonconforming items were found in the audit, we strove to make continuous improvements.

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 the first half of FY2022, the course was held on video-on-demand (monitoring experience was also provided only for viewing) due to the expansion of COVID-19 infection.
In the second half of the fiscal year, the seminar was held online and monitoring was conducted via a live broadcast from the river. A total of 78 participants took the course in the first and second semesters.
Furthermore, we held a career development course, "CSR (Intermediate Level)," for employees who have been with the company for about 10 years.
A total of 128 participants took the course, which covered knowledge on SDGs, ESG investment, and other CSR issues such as the environment, health and safety, Disaster Prevention and BCP.
These career development courses are positioned as mandatory training for promotion.
823 employees have participated in CSR training so far, or 16% of the Yokohama Rubber non-consolidated total.
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 98 personnel who have completed this course to get certified in fiscal 2022, currently a total of 2,548 personnel have been registered and are already active as our internal auditors. (45% are qualified internal auditors in the scope of the integrated certification.)
We conduct skill improvement seminars to further improve the levels of employees with internal auditor qualifications. This time, due to the Corona disaster, it was not conducted.

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 2022, we resumed the campaign and received 5,902 entries for eco declarations and 110 entries for posters in Japan, and 6,629 entries for eco declarations and 403 entries for posters overseas.
Of these, the following were selected as excellent works.
