Environmental Efficiency / Environmental Accounting

We assess the environmental efficiency of our production and research sites to evaluate their environmental efforts in a quantitative form. In addition, we have disclosed environmental accounting data in reference to the Environmental Accounting Guidelines (2005 edition) issued by the Ministry of the Environment of Japan.


● Assessment of Environmental Efficiency

We disclose an indicator that shows the efficiency of our environmental conservation activities in reducing environmental impact. To calculate this indicator, we classify the company’s environmental impacts into five categories: chemical substances, global warming, waste, water quality, and air quality. We then select a typical environmental factor for each of the categories and divide their amount of environmental impact by the net sales in the relevant fiscal year. The resulting figure is then used to assess the level of reduction in environmental impact achieved through environmental conservation activities.
The environmental efficiency indicator for FY2016 improved by 33.2 points compared to FY2005. This was due to sales growth although CO2 emissions, BOD load, and NOx emissions recorded a year-on-year increase.
We will remain committed to reducing our environmental impact and improving the environmental efficiency indicator.

● Environmental Costs and Effects in FY2016

The environmental investment at our main production and research sites during FY2016 was for global warming countermeasures and other environmental measures.
