Management of substances that have impacts on the atmosphere and hydrosphere

Toshiba Group is working to grasp the extent of emissions of sulfur oxides (SOx) and nitrogen oxides (NOx), both of which are major causes of air pollution, as well as the level of chemical oxygen demand (COD), an indicator of water pollutants, and emissions of total nitrogen and suspended matter to ensure appropriate management of such emissions. In addition, each business and production site voluntarily sets the maximum permissible levels of concentrations for these substances and complies with these prescribed standards. Moreover, in recent years, the Group has been working to improve productivity in reducing environmental impacts. Besides harnessing existing processing facilities' reserve capabilities, the Group is also conducting pioneering efforts such as increasing performance depending on loads and using waste liquids to treat wastewater.

Impacts on the atmosphere
Amount of impact = Concentration of each substance × Amount of substance emitted (based on the Air Pollution Control Act)

Impacts on the hydrosphere
Amount of impact = Concentration of each substance × Amount of substance discharged (based on the Water Pollution Control Act)
