  • [1]GHG emissions are reported for the calendar year. The methodologies and emission factors applied for the development of a GHG emissions inventory were in accordance with the ‘Guidelines to Account for and Report on Greenhouse Gas Emissions and Removals for Buildings (Commercial, Residential or Institutional Purposes) in Hong Kong, 2010 Edition’ issued by Electrical and Mechanical Services Department and Environmental Protection Department. AAHK follows the operational control approach in defining its organisational boundary which covers buildings and facilities that AAHK has control over. The inventory covered seven types of GHG, namely carbon dioxide (CO₂), methane (CH₄), nitrous oxide (N₂O), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), sulphur hexafluoride (SF₆) and chlorodifluoromethane (HCFC-22). The inventory of GHG emissions has been verified by TÜV Rheinland Hong Kong Ltd.
  • [2]Scope 3 emissions are the GHG generated from paper disposal at landfill and electricity consumption for processing fresh water and sewage.

  • [1]AAHK adopts a "triple water system" to improve the efficiency of our three major water sources: freshwater, seawater and treated wastewater, details of which are available on our website.
  • [2]The volume of wastewater discharge is estimated by subtracting the volume of wastewater recycled from our municipal water consumption. Under the Water Pollution Control Ordinance (Chapter 358, The Laws of Hong Kong), AAHK holds a number of licences which require the monitoring of water quality using the following parameters: flow rate (m³/day), total residue chlorine, amines, temperature, antifoulant, suspended solids, chemical oxygen demand, oil and grease, surfactants (total), biochemical oxygen demand, total phosphorus and formaldehyde. In 2016/17, all discharges were in compliance with licence discharge limits.
  • *The 2015/16 figure has been restated following an internal database review.
