At Hong Kong International Airport (HKIA), we are committed to complying with statutory air quality criteria, understanding and managing our own air emissions, and minimising them wherever we can.

For many years, the Airport Authority (AA) has been implementing a number of initiatives aimed at reducing air emissions from airport activities and operations. In May 2007 HKIA strengthened its commitment to improving air quality by signing the Clean Air Charter, and since then the airport has achieved many of the Charter commitments.

We will continue to minimise air pollutants through the following initiatives:

  • Provide a liquefied petroleum gas (LPG) fuelling point for airside vehicles and ground support equipment
  • Provide charging stations for airside and landside electric vehicles
  • Increase the use of fixed ground power and pre-conditioned air systems by aircraft and prohibit aircraft with idling engines at parking stands from 2014 to reduce aviation fuel burn and associated emissions
  • Require all new airside vehicles to be fuel-efficient, and make it a prerequisite for the licensing process
  • Provide the cleanest diesel and gasoline at the airfield as required by the government
  • Ban all idling engines on the airside since 1 June 2008, except for certain vehicles and equipment that are exempted due to safety and operational considerations
  • Replace our entire vehicle fleet with electric or fuel-efficient / hybrid vehicles in phases. By 2017 all saloon vehicles on the airside will be electric
  • Promote increased use of electric vehicles (EVs) and ground service equipment (GSE) at HKIA by working closely with our business partners to ensure that charging infrastructure is provided and / or upgraded on the airside
  • Require all of the AA's diesel vehicles to use biodiesel (B5). Click here for details.
All airside saloon vehicles will be replaced with electric powered vehicles by 2017

Air quality monitoring

HKIA continuously tracks outdoor air quality through two airport monitoring stations and a third station on Sha Chau, an island several kilometres to the north of HKIA. The wealth of data we collect helps us monitor regional air quality and keep track of the progress of our pollution reduction initiatives.

In addition, the Institute for the Environment of the Hong Kong University of Science and Technology has conducted an Airport Operational Air Quality Study. Click here for details.

Indoor air quality

We endeavour to maintain a healthy environment for our passengers and staff by monitoring indoor air quality. The SkyPier, North Satellite Concourse, Terminal 1 (T1) and Terminal 2 (T2) have all received a Good Class certificate for good indoor air quality from the Environmental Protection Department.
