Environmental Burdens from Business Activities

Knowing what impacts our business activities have on the environment is the first step in carrying out environmental preservation activities. We will work to reduce our environmental burden by grasping the amounts of our inputs (such as the raw materials and energy used by our Group) and the amounts of our outputs (such as the products shipped, CO₂ emissions and the wastes emitted outside the Group as the result of our business activities).
The material balance showing INPUT and OUTPUT is described below.
