Target amount of year 2016: Reducing 1,653 tons of CO2 emission by the end of December. We ve reduced 1,698tons of CO2 emission by reducing consumption of electricity and fuel on our production management. Conservation of Resources Reduction of gold consumption. Target amount of year 2016: Reducing 729g of gold usage amount by the end of December. We ve reduced 729g of gold consumption by switching bonding wire material from gold to copper. Environmental Improvement Activities for All of Us. Arbitrarily set according to the target Environmental Mass Balance Each dept. consults on 22 activities that they extract from their duties. Main activity: Promoting improvement activities of energy saving and resource saving. Intensifying the number of operations chief of organic solvents work. Controlling material stock amount. Training of Chemical receiving spill. Reducing industrial water. Each dept. virtually achieved their target. Assessment Standards of the Achievement level :110% or more. :From 95% to less than 110% :From 80% to less than 95% :From 65% to less than 80% :Less than 65% To produce semiconductors, it needs large amount of energy and chemicals. ASE Japan measures the environmental load of its operations accurately and utilizes the data in order to reduce it.
