Remarks:
  1. These calculations involved conversion factors as provided in the GRI G3 Guidelines Indicator Protocols and on Towngas bills.
  2. Diesel used for the emergency generator was included, while diesel used for the vehicle fleet was excluded.
  3. Water consumption was calculated based on water bills issued by the Water Supplies Department. Except for three water accounts that have not received water bills since 29 April 2019, water consumption data covered the whole reporting year.
  4. Treated water was discharged from PolyU’s pre-treatment facilities.
  5. Increase in treated wastewater discharge was recorded in the reporting year as large-scale laboratories cleaning was carried out in August 2018.
  6. CO2, CH4, N2O and HFCs were included in these calculations.
  7. Figures of 27,621 students and staff members (22,281 FTE students and 5,340 full-time staff) were used to calculate the per capita intensity.
  8. Due to enhancement of data collection mechanism, 2018/19’s paper consumption only included those consumed by PolyU Main Campus, whereas 2014/15’s paper consumption included those consumed by all PolyU entities.
  9. A4 paper with recycled content was excluded.
  10. Electrical and electronic equipment covered monitors, notebook computers, desktop computers, tablets, printers, scanners and servers.
  11. Collection service for reuse of electrical and electronic equipment was suspended since March 2019.
  12. This estimate is based on a weight of 57 kg per 240 L collection bin.
