setting optimum speeds for
climb, cruise and descent of
the fl ight;
enhancing engine wash to
improve fuel effi ciency;
better managing water uplift to
reduce aircraft weight and
fuel uplift;
introducing lightweight meal
carts and serviceware;
using more energy effi cient
lightings, refl ectors and motion
sensors at the workplace to
reduce energy use;
adopting zonal control to turn
off lightings;
using more energy effi cient
variable speed motors for Air
Handling Units;
• using environmentally-friendly
refrigerant for air-conditioning
chiller plants, and emulsion
paints with less VOC emissions;
and
• using recycled materials
for new ceiling boards and
partitions for offi ces.
These initiatives would lead to an
estimated reduction of 550,000
tonnes of carbon emissions.

environmental efforts are available

by air transport over the last three
decades to improve fuel effi ciency
by 70%, the industry remains
under tremendous pressure to
reduce its carbon footprint and is
expected to accomplish more.
The Airline strives to lead by
example, by showing that business
can be competitive, yet act in
an environmentally responsible
manner. It continues to engage
engine-makers and other suppliers
to make their products cleaner,
greener and quieter.
During the year in review,
Singapore Airlines took delivery
of 12 new aircraft – three A380s,
ve B777-300ERs and four A330-
300s. These new aircraft are
quieter, boast substantially lower
fuel burn per-seat-kilometre, and
have lower carbon emissions.
The Airline also retired six
Boeing 747-400s, which were
comparatively less fuel-effi cient and,
therefore, produce higher emissions.
During the year, environmentally-
friendly initiatives both in the
air and on the ground were
introduced. These include:
• partnering with airport
authorities to develop shorter
and more direct fl ight routings;
selecting alternate airports that
are closer to destination cities,
thereby reducing fuel uplift,
aircraft weight and fuel burn;
