Within the framework of sustainable life, environmental criteria are defined for purchasing operations based on suppliers and the materials purchased; and compliance of the suppliers with the determined criteria are controlled.

Environmental compliance of the purchased materials is assured by regularly following industrial developments and integrating legal directives and regulations such as RoHS, WEEE and REACH into purchasing operations.

Environmental performance of the suppliers is evaluated by inspections and audits. The suppliers are encouraged to cooperate with R&D for the supply of materials and components needed for less resource consuming, more environment-friendly and innovative products, and the suppliers are expected to support design projects.
