In the past year, we have begun tracking indoor air
quality at our shopping centres in order to maintain a good air quality
standard and make improvements if necessary. We are working with other
government departments to improve the air quality of our public transport
interchanges where necessary and have designed those in new developments
based on Environmental Protection Department's (EPD) guidelines.

In recent years, we have taken many steps to eliminate
chlorofluorocarbon (CFC) and hydrochlorofluorocarbon (HCFC) gases
from our premises and operations. Our latest initiative is that since
October 2001, we require all our contractors to use CFC/HCFC-free
materials in all new and re-roofing works.

| Through our recent surveys, we know that radon levels
in occupied flats do not pose a risk to our residents' health. However,
just as a precaution, we recommend residents maintain good ventilation
in their flats. |

Retrofitting Chillers
We have decided to replace our two remaining chillers that contain
ozone-depleting gas with water cooled systems. This will bring about
energy savings and will avoid using chemical coolant. We expect the
replacement works to be completed by mid 2004. |
