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 2014 Environmental Accounting

Environmental accounting

The new assembly factory at the Saitama Plant began operations in FYE 2014. It includes a great number of energy-saving measures such as photovoltaic power generation, LED lighting throughout the building, GHP (Gas Heat Pump) air conditioning, green roofs, and the use of insulating glass. In addition, this was a fiscal year that saw major energy savings obtained through investments, with one such example being the installation of gas-powered equipment for air conditioning and boilers at group company Tsubaki E&M. For the entire group, CO2 emission reductions were at least twice as high as a normal year (approximately 1,100 tons/year).
*GHP = Gas Heat Pump. A heating and cooling system that uses a gas engine to operate an air compressor.
