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 2015 Environmental Accounting

Environmental accounting

In the previous fiscal year, we made large-scale environmental investments such as those in photovoltaic power generation (Saitama Plant) and GHP* (Tsubaki E&M), but such investments were reduced in FYE 2015. However, CO2 emission reductions greater than or equal to those of an average year were obtained through initiatives such as improvements to productivity and the operation of utility equipment. 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.
*GHP = Gas Heat Pump. A heating and cooling system that uses a gas engine to operate an air compressor.
