HKUST Sustainability 23 Environment Social and Governance Report 2021-22 Water Consumption Overview in 2021/22 Water Consumption Breakdown 2021/22 Water consumption in the 2021-2022 academic year increased by 10.5% from the level in the previous year. In this academic year, HKUST consumed approximately 375 million litres of water, which is equivalent to nearly 150 Olympic-sized swimming pools. Of all buildings in HKUST, the main academic buildings, canteen and commercial buildings, and student housings have the most water consumption proportion, which is 31%, 22%, and 14%, respectively. Compared to the prior academic year, the water consumption in main academic buildings increased by 43%. This notable increase happened due to the face-to-face course resumption and operation of cooling towers on the library rooftop. Also, compared to the prior academic year, HKUST experienced a 17% increase in water consumption per capita, which was approximately 20 m3 of water consumption equivalent to 40,000 bottles of water. 500K 450K 400K 350K 300K 250K 200K 150K 100K 50K 0K Cublic Meter Canteen & Comm...

While water is a fundamental source of energy that living organisms need for survival, there is an ongoing water crisis in economies and societies. To cope with this issue, we understand the significance of providing sufficient water availability to the community and transforming our water management systems to reduce total water consumption.
