Background to Identification as Materiality

Significance for TDK

By facilitating the sharing of information about procurement conditions and issues throughout the Group, “enhance global procurement capabilities and mechanisms,” which is one of the themes, will lead to increased work efficiency and cost reduction. Promotion of the other two themes, “ensure responsible procurement” and “ensure societal and environmental consideration in the supply chain,” will enable the building of a competitive supply chain.
Specifically, the establishment of a pleasant working environment contributes to improving the health and productivity of employees and, moreover, leads to the attraction and retention of talented human resources. In addition, today, when consideration of social issues, such as human rights, and the environment has become an essential condition of business, such initiatives clearly have an influence on relations with business partners and investment decisions by shareholders and investors.
Since these activities generally improve quality, delivery, and cost throughout processes and exert a positive impact on the environment, human rights, and other issues, they can be expected to lead to the enhancement of customer satisfaction, the gaining of trust from employees and investors, and in turn the growth of the TDK Group.

Significance for Society

TDK has numerous manufacturing sites and about 4,500 suppliers around the world. The promotion of societal and environmental consideration at these sites and suppliers is highly significant not only for TDK but also for society at large.
Furthermore, we recognize that stakeholders have expectations for not only response and compliance with legislation and international industrial standards in the supply chain but also the execution of social responsibilities, such as support for suppliers, and the minimization of social impact caused by corporate (business) activities, such as the problem of conflict minerals.

Responsible Theme

  • Ensure societal and environmental consideration in the supply chain

TDK, which aims to achieve both a sustainable society and corporate growth, has numerous manufacturing sites around the world, so efforts to reduce societal and environmental risks at sites are an important activity with significant impact. Utilizing RBA* standards, we regularly check by means of multiple methods, including third-party perspectives, whether manufacturing sites have a suitable working environment, whether workers are treated with respect, whether substances that are harmful to human beings and the environment are being managed and processed properly, and so on.
We started these activities about 10 years ago, and we have moved forward while making repeated improvements. At all times, the important thing is to identify what social issues will arise and attract attention going forward and to respond to those issues as quickly as possible. Manufacturing sites are required to steadily correct findings pointed out in audits and CSR assessments, to maintain these corrected conditions, and to predict risks that might occur due to the same reason and deal with them beforehand.
To realize the ideal that we are aiming for, we will promote activities based on the understanding and cooperation of everyone at manufacturing sites, the CSR and Safety and Environment Group at Regional HQs, business divisions, and the Global HQ divisions.

* RBA stands for the Responsible Business Alliance, the world’s largest coalition of companies in the electronics, retail, auto, and toy industries. The RBA stipulates a code of conduct for the improvement of occupational safety and health, the protection of human rights, consideration for the environment, and ethical responsibility in the supply chain and urges member companies and their suppliers to practice the code.
