compared with FY2014. We had also
managed to reduce Scope 2 emissions
per production output by 3.6% and
natural gas usage by 5.8%. For the
coming year, VTech will continue to
replace the diesel with natural gas
at the manufacturing sites, and only
maintain a small amount of diesel usage
for our back up electricity generators.

Energy Recycling in Burn-in
Process
“Burn-in” process is a stress test on
the electronic components of our
products during the quality assurance
stage in our manufacturing process. As
this specific process requires intensive
energy consumption, our RECT has
introduced an energy recycling system
in the burn-in process so that a large
amount of excessive energy can
be retrieved and reused during the
process, which has helped us to reduce
75% of the in-process energy after
installing the system.

Carbon Emissions
The operation of VTech results in both
direct (Scope 1) and indirect (Scope
2) emissions from the use of energy.
Our energy conservation programmes
and activities are driven by our desire
to reduce the energy consumption
and thus the carbon emissions. As
illustrated in the following charts, as
direct emissions (Scope 1) only account
for less than 5% of our total carbon
emissions in the manufacturing sites,
the dominance of electricity (Scope 2)
is more noticeable in our operations.
This is why most of our energy saving
activities are focused on reducing
electricity consumption.
In FY2015, our total Scope 1 and
Scope 2 emissions were 108,757
tonnes CO

e. Due to the gradual
phase-out in the use of diesel at the
canteens of our manufacturing sites,
our total diesel usage had decreased
by 47.8% which resulted in a reduction
of Scope 1 emissions by 21.8%

Energy Consumption
In FY2015, the total energy
consumption increased by 3.0%
which was mainly attributable to the
increase in production output. With
our continuous efforts on improving
the energy efficiency in our production
chain, the electricity consumption per
production output in our manufacturing
facilities reduced by 5.4% compared
with FY2014.
On the other hand, our continuous
improvement programmes in the
living areas, including the upgrade of
the air conditioning systems at the
dormitories and canteens, increased
the total electricity usage in the non-
manufacturing areas of our factories in
FY2015 compared with the previous
year. We will continue to promote
resources conservation programmes
in the living areas of our factories, but
without compromising the provision
of a comfortable and pleasant living
environment for our employees.
