The environmental assessment was mainly for the manufacture process change applying of TSMC, which will increase the water and power consumption. And according to the Taiwan’s regulations, it has to conduct a environmental assessment to confirm the difference of changes.

TSMC said the production of 5-nanometer process will increase of 43% of power consumption and 37% of water consumption relative to the 28-nanometer. And the 5-nanometer process is expected to start next year after obtaining the permission.

And due to process change, Tainan Science Park of Taiwan need to increase 50,000 tons of water and 700,000 kilowatts of electricity consumption per day.
