Environmental Approach

The Tsubaki Group utilizes environmental accounting to quantify the economic and ecological benefits obtained through its environmental conservation activities as well as the cost of these activities. We use this information to analyze the progress of environmental conservation activities and implement continuous improvements. Here we provide a summary of our main environmental accounting data.

FYE 2017 Environmental Accounting

Environmental accounting

In FYE 2017, we made various energy-saving investments including adoption of a high-efficiency heat treatment furnace and increased adoption of other energy-saving equipment. In addition, expenses related to restructuring utility equipment operation and activities for improving productivity were on par with the previous fiscal year. The Tsubaki Group utilizes its environmental accounting system to analyze the cost of environmental conservation activities and the economic and ecological outcomes of these activities, as well as to reflect these findings in future activities. This system is also used to disclose information.
