Remarks:
  1. Conversion factors used to standardise the units to gigajoules (GJ): diesel (0.036GJ/L), gasoline (0.033GJ/L), electricity (3.6GJ/MWh).
  2. The emission factor of greenhouse gas emissions due to electricity consumption is obtained from the CLP Sustainability Report 2019: 0.50 kg CO2 e/ kWh.
  3. Diesel used for the emergency generator was included, while diesel used for the vehicle fleet was excluded.
  4. Water consumption was calculated based on water bills issued by the Water Supplies Department.
  5. Treated water was discharged from PolyU’s pre-treatment facilities.
  6. Made reference to the Guidelines to Account for and Report on Greenhouse Gas Emissions and Removals for Buildings of Commercial, Residential or Institutional Purposes in Hong Kong (by the Environmental Protection Department and the EMSD).
  7. CO2, CH4, N2O were included in these calculations.
  8. Figures of 27,979 students and staff members (22,723 FTE students and 5,256 full-time staff) were used to calculate the per capita intensity.
  9. Due to enhancement of data collection mechanism, 2019/20’s paper consumption only included those consumed by PolyU main campus, whereas 2014/15’s paper consumption included those consumed by all PolyU entities.
  10. A4 paper with recycled content was excluded.
  11. Electrical and electronic equipment covered monitors, notebook computers, desktop computers, tablets, printers, scanners and servers.
  12. Collection service for reuse of electrical and electronic equipment was suspended since March 2019.
