Indoor Air Quality (IAQ)

EMSD has pioneered periodic IAQ measurement for its clients since the mid-1990s. Over the past several years, EMSD has been actively involved in formulating the IAQ management programme and assisting in the preparation of Guidance Notes for participation and certification in the programme. In 2001, we  surveyed 72 buildings in a pilot scheme. The experience gained in this pilot scheme has been fed back to the Environmental Protection Department and other concerned bureaux/departments to help mapping out the way forward.

  LPG Vehicles

As Hong Kong's Authority on Gas Safety, we are closely involved in regulating all the safety aspects of the LPG schemes. These include mandatory safety controls and approvals of  LPG vehicles, LPG filling stations, LPG vehicle workshops and competently trained LPG mechanics. In addition, our active involvement in coordinating the construction of all LPG filling stations has helped to accelerate the development of an improved auto-LPG filling station network and speed up the replacement of diesel taxis with LPG models. As at the end of 2001, there were a total of 19 LPG filling stations in operation and over 14,100 LPG taxis on the road. We expect another 26 LPG filling stations to become operative by the end of this year. We will continue to work with other Government departments towards the eventual replacement of all the 18,000 diesel taxis in Hong Kong with LPG models by the end of 2005.
