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 these where practicable.

A number of initiatives aimed at reducing air emissions from our activities and operations have been underway for many years. To strengthen our commitment to improving air quality, HKIA signed the Clean Air Charter in May 2007 and we have now achieved many of the Charter commitments. We will continue to minimise air pollutants by:

  • Providing an LPG fueling point for airside vehicles and ground support equipment;
  • Increasing the use of Fixed Ground Power and Pre-conditioned Air by aircraft at frontal gates;
  • Requiring all new airside vehicles to be fuel efficient as a pre-condition for the licensing process;
  • Providing the cleanest diesel and gasoline in our airfield area;
  • Enforcing our vehicle idling engine shutdown mandate in place since 1 June 2008;
  • Replacing by phases of our entire vehicle fleet with electric or fuel efficient/ hybrid vehicles;
  • Promoting increased use of electric vehicles (EVs) and ground service equipment (GSE) at HKIA by working closely with our business partners to ensure charging infrastructure is provided / upgraded in the airport restricted area and by increasing the take up of EVs and GSE at HKIA;
  • Requiring all diesel vehicles of the Airport Authority to use biodiesel (B5).
  • Facilitating the provision of biodiesel (B5) in the airport restricted area in 2010.

Air quality monitoring

HKIA continuously tracks outdoor air quality through two airport monitoring stations and a third station on Lung Kwu Chau, an island several kilometers to the north of HKIA. The wealth of data collected helps us monitor regional air quality and keep track on the progress of our pollution reduction initiatives. An Airport Operational Air Quality Study was conducted recently by Institute for the Environment, The Hong Kong University of Science & Technology.

Indoor air quality

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