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.
Although our waste temporarily increased from the previous year due to renovation work on the investigational drug-related facilities carried out at the Joto Plant, the environmental efficiency indicator improved by 45.0 points due to the increase in sales in FY2017.
We will remain committed to reducing our environmental impact and improving the environmental efficiency indicator.

● Environmental Costs and Effects in FY2017

The environmental investment at our production and research sites during FY2017 was for global warming countermeasures and other environmental measures.
