Environmental conservation costs: Compared to the previous fiscal year, in FY2018 investments for environmental conservation increased significantly and expenses decreased.
The reason for the increase in investment amount is the introduction of a smoke exhaust system at some overseas works, based on the strengthening of local laws.

Economic Benefits: Economic benefits for FY2018 increased from the previous fiscal year. This was the result of an increase in sales revenue of waste with value at overseas works, the effect of reuse of production equipment, and the effect of the sale of electric power generated by photovoltaic power generation systems.

Environmental Conservation Benefits (Reduction of waste): As for environmental conservation benefits, although industrial waste discharge per unit of production value decreased as a result of its environmental improvement activities, but the CO2 emissions per unit of production value , the amount of landfill waste and the amount of generated environmental hazardous substances all worsened.

Actual results of Power Generation at photovoltaic power systems

Photovoltaic power systems owned by SMK and subsidiaries generated 1.26 million kWh of electricity in FY2018. The CO2 reduction effect was 400 t-CO2.
