Environmental
Responsibility
Environmental sustainability
is a guiding principle for the
Qantas Group.
We are committed to reducing our energy
use, cutting emissions from our ights
and property, and making a positive
contribution to the environment through
our own actions and partnership with
environmental groups.
Fuel efciency is a priority, given that jet
fuel is the Qantas Group’s single largest
cost and is responsible for 95 per cent
of our emissions. Our average aircraft
age is now 7.9 years, the lowest since
privatisation, as we renew our eet
with more efcient aircraft. Qantas and
Jetstar are also leading the way in the
development of cockpit technology that
can help reduce fuel burn.
Looking to the future, we are investigating
the next generation of sustainable
aviation fuels. In collaboration with the
Federal Government and Shell, weare
conducting a feasibility study into the
prospects for aviation biofuel in Australia.
On the ground, a highlight of 2012/2013
was the launch of a trigeneration
plant to power our Sydney ofce
andoperationscomplex.
Qantas’ environment strategy was
recognised in 2012 with a prestigious
Banksia Award in the corporate
leadership category, and we are
represented on a range of international
sustainability indices.
Trigeneration in Sydney
»Trigeneration is a low-carbon form
of energy production that is more
than twice as efcient as traditional
coal-red generation.
»An engine powered by natural gas
generates electricity, and the excess
heat from the process — which would
otherwise be lost — is captured and
redirected to provide hot water,
refrigeration and air conditioning.
»Qantas’ Sydney facility is expected to
help cut carbon emissions by around
14,000 tonnes per year — the equivalent
of taking 3,500 cars off the road.
»More than 4,000 employees work in
the buildings that will be powered by
the facility — Qantas’ corporate ofce
buildings, catering centre, jet base
and domestic terminal.
»The facility is Australia’s largest
commercial trigeneration plan and is
expected to help increase the green
energy rating of Qantas’ Sydney
headquarters from one-and-a-half
to ve stars.
Qantas is researching
the potential for aviation
biofuels to cut carbon
emissions.
