Promotion System

Our group has a matrix-type structure including the internal company and respective regions, promoting environmental activities while having individual roles clarified. Each internal company is expected to manage its own targets on items relevant to business activities. Meanwhile, we take the initiatives to such activities as compliance of regulations, raising environmental awareness, and communication with local society mainly on the regional basis in accordance with action plans. Various working groups are set up as the cross-functional team across the internal company for promoting activities.
The activities will be confirmed with respect to the progress toward the target, and task in the Central Environmental Committee at which President, directors, company presidents, regional environmental administrators, and heads of the working group are present for continuous improvement.

Compliance with Environmental Laws and Regulations

To ensure compliance with environmental laws and regulations as well as agreements with local municipalities, we set stringent voluntary standards to prevent violations and complaints.
In fiscal 2020, there were two violations and two complaints. Against a violation or complaint that occurred, we take measures immediately, including those to prevent recurrence.
