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.
