Moreover, HKUST is striving to lessen its contribution to the demand for fossil fuels and the corresponsing emissions by responding and addressing energy usage from non-renewable sources. Due to the gradual return to normal operations and the construction of 3 new buildings, Global Graduate Tower, Water Sport Centre, and Shaw Auditorium on campus, HKUST’s energy consumption in the 2021-2022 academic year increased by 2% from the level in the previous year. Electricity is the main source of energy in HKUST (94% of total energy comes from electricity), it serves well as an indicator of how well we are preforming in terms of greenhouse gas emissions and air pollution. Over the past year, there was a 2% increase in electricity consumption, which became the major driver of the overall energy consumption. Town gas, which is mainly used for cooking at canteens and domestic hot water in residence halls and staff quarters, accounts for 5% of the total energy usage. The remainder of campus energy comes from liquid fuels for standby generators (stationery diesel) and transportation vehicles such as diesel and unleaded petrol.
