Project/Year 2021 2022 2023

Water intake (use) (million liters) 50,648 52,475 52,141

Water consumption (million liters) 13,962 16,320 16,456

Water intake (use) intensity (million liters/NT$ 100 million) 4.89 4.49 5.56

Note:
1. The denominator of electricity consumption and water intensity is the total turnover of Central Taiwan Science Park
in the current year. (The turnover in 2021 was NT$ 1,035.232 billion, NT$ 1,169.8 billion in 2022 and NT$ 938.4 billion in
2023).
2. Every kilowatt hour =1kWh=3,600 kilojoules.
3. Water consumption = water intake-water discharge.
4. The water consumption does not include Zhongxing Park.

Since 2007, CTSP has conducted water-saving counseling for 48 times so far, with a
3
cumulative water-saving potential of 11.98 million M /year, which can equate to save
7.54 water of Shigangba Reservoir every year (the effective capacity of Shigangba is
3
1.605 million M ) and reduce the emission of 1,870 metric tons of CO 2 e/ year. In 2023,
CTSP conducted water-saving counseling for 3 times, with a total water-saving potential
of 153,333. In addition, according to the CO 2 e of 1-degree water announced by Taiwan
Water Corporation in 2023, the benefits of "energy saving and carbon reduction"

3
measures can be converted. For every M of tap water saved, the CO 2 e emission can
equate to be reduced by about 0.156 kg, and the CO 2 e can be reduced by 23.92 metric

tons per year.
