Environmental Performance Reducing Our Carbon Footprint & Conserving Resources
Conserving Resources
The 5Rs principle – to Replace, Reduce,
Reuse, Recover and Recycle – form the basis
of our conservation programmes. We thus
make every effort to save energy, cut down
the use of resources, recycle equipment and
materials as well as reduce the generation
of waste.

Saving Electricity
Though our headquarters in Hong Kong achieved its classification as an Energy-
efficient Building under Hong Kong’s Energy-efficiency Registration Scheme, we are
continuing the improvement of its energy efficiencies. In 2010, the building gained
its BEAM (Building Environmental Assessment Method) certification, Platinum Grade
(version 5/04) and in 2011, we conducted a further gap analysis study to achieve BEAM
Plus certification. BEAM is Hong Kong's top tool for the assessment of a building’s
environmental performance from a full life-cycle perspective.
