5Rs Principle
Looking to reduce our carbon footprint even
further while providing a greener choice for
customers, we completed our study on the carbon
footprint of a typical gas appliance during the year.
The study took the entire life-cycle of the appliance
into consideration from the acquisition, processing
and use of rawmaterials to its manufacturing,
storage, transport and distribution, as well as its
actual usage, disposal and recycling possibilities.
Assuming the whole product life span of a gas
cooking appliance is 10 year, the study results
showed that it is the appliance’s usage phase
that makes the largest contribution (more than
90%) to its carbon footprint. Factors affecting the
emission include the quality of feedstock and fuels
used during gas production process, efficiencies
of production process and cooking appliances, as
well as users’ habits. With regard to the areas which
lie under our operational control, we continue to
look for opportunities and technologies to improve
performances. At the same time, we are continuing
the product carbon footprint study looking into
possible methods which can help customers to
save energy during cooking process. Our aim is to
provide our customers with useful and practical
gas saving tips based on scientific figures.
Conserving Resources
With the 5Rs principle – to Replace, Reduce, Reuse,
Recover and Recycle – forming the basis of our
conservation programmes, we make every effort to
save energy, cut down the use of resources, recycle
equipment and materials as well as reduce the
generation of waste.
