Carbon Intensity
Looking to reduce our carbon
footprint even further while
providing a greener choice for
customers, our newly formed Green
Development Steering Committee
is also researching the carbon
footprint of a typical gas appliance.
The study takes the entire life-cycle
of the appliance into consideration
from the acquisition, processing
and use of raw materials to
manufacturing, storage, transport
and distribution. It also takes the
actual usage of the product into
account as well as its final disposal
and recycling possibilities.
“Over the past two years, our Carbon Reduction Project Competition
on the mainland has brought in a total of 85 submissions reducing
carbon emissions by a total of 23,000 tonnes annually. In addition
to the cost-savings, this translates into the CO
2
absorbed by 995,000
trees every year.”
Environmental Performance Reducing Our Carbon Footprint & Conserving Resources
In view of the success of our Carbon Reduction Project Competition held by our
mainland businesses in 2010, the exercise was repeated once again in 2011. The
results have been equally positive. A total of 47 submissions were received, reducing
carbon emissions by 10,000 tonnes during the year, equivalent to the amount of CO
2
absorbed by 430,000 trees annually. The winning proposal, which came from the
Suzhou Water Company with the simple suggestion to prevent rainwater from entering
the wastewater system, reduced the amount of wastewater to be processed by an
impressive 3 million tonnes in one year alone, saving over RMB3 million in costs and
885 tonnes of CO
2
emissions annually.
