SUSTAINABILITY & ENVIRONMENT
Most recently, in late April, airports throughout the region received
their certificates at the ACI Asia-Pacific Regional Assembly in Doha,
Qatar. Hyderabad and Sunshine Coast both received their neu-
trality certificates. Qatar ’s Hamad International Airport, Thailand’s
Suvarnabhumi Airport and Australia’s Sydney Airport all climbed
to the Level Three Optimisation rank. Japan’s Kansai International
and Osaka International both reached Level Two Reduction status,
while Beijing Capital Airport, Australia’s Gold Coast Airport, Oman’s
Muscat International Airport and Fiji’s Nadi International Airport
achieved Level One Mapping accreditation.
At ACI’s regional assembly, Asia-Pacific regional director Patti
Chau said: “Airports in our region have made remarkable progress
in their journey towards carbon neutrality. Last September, we wel-
comed our very first carbon neutral airport and in just a few months
we welcomed another two carbon neutral airports.” Chau added:
“Going forward, we will continue to encourage airports to establish
targets on carbon emissions reduction and work with our members
to achieve sustainable growth.”
Airports throughout the region — including numerous airports in
Australia, Cambodia, China, India, Japan, Korea and Thailand — are
already participating in the programme and moving up the ranks.
The latest to achieve carbon neutrality are Australia’s Sunshine
Coast and India’s Bangalore international airports.
Sunshine Coast Airport has spent the last five years working
towards carbon neutrality, setting a target of 2018 to reach carbon
neutrality. The airport implemented an “innovative and holistic ap-
proach”, which included rainwater harvesting, waste composting,
recycling programmes, water usage reduction and low energy
lighting and air conditioning.
The airport implemented energy management systems that allow
the business to respond immediately to customer demand. This
includes automating the air conditioning system to be responsive
to flight schedules and varying set temperature points through the
day based on demand and loads. Large-scale, energy-efficient fans
were also installed through the building to create air movement and
reduce air conditioning requirements, while air curtains and skylight
shading reduced the heat load. Lights in signage, car park floodlights
and general user areas were replaced with LEDs.
In the area of waste, the airport installed Australia’s first solar-pow-
ered on-site composting apparatus, which is an automated, aerobic
composting system capable of handling up to 945 litres of waste
per week. A three-way bin system was introduced and the airport
worked with its tenants to reduce waste.
Water usage was reduced through rainwater harvesting and ef-
ficiency upgrades, including an urban sensitive land design which
reduced the irrigation requirement, rainwater tanks on the terminal
roof for use in amenities and landscaping and the installation of
water efficient taps and appliances.
As a result of these programmes, the airport has achieved a 24
percent reduction in scope one and two carbon emissions; an 11
percent reduction in waste to landfill per passenger; a 50 percent
reduction in lighting energy requirements; a 9 percent reduction in
electricity consumption per passenger; and a 15 percent reduction
in water consumption.
Likewise, Bangalore International Airport (BIAL) embarked on its
green journey a number of years ago. “BIAL’s approach to sustaina-
bility incorporates understanding and learning from experience, and
we have progressively developed capabilities to respond to industry
best practices,” says Sanjay Reddy, managing director. He adds:
“As one of the early adopters to become airport carbon accredited
when the programme first launched in Asia-Pacific six years ago,
our journey to carbon neutrality has been steadily well-documented
as we rose through the four levels of Airport Carbon Accreditation.
BIAL continues to work in collaboration with its partners within
the eco-system to improve and reduce energy, constantly working
towards carbon neutrality.”
Elsewhere in the region, Bangkok’s Suvarnabhumi Airport and
Australia’s Adelaide and Sydney airports have all moved up to level
three optimisation. Fiji’s Nadi International Airport,
meanwhile, has embarked on its carbon accredita-
tion journey, reaching level one mapping, while be-
coming the first airport from an island nation under
threat from climate change to join the programme.
Sydney Airport has wide-ranging environmental
initiatives in conjunction with its airport business partners which
are delivering results. “Sydney Airport has already delivered a 25.6
percent reduction in carbon emissions per passenger since 2010, well
ahead of our target date,” says Kerrie Mather, managing director and
chief executive officer. “ We’ve also achieved an absolute reduction
of 8 percent — a great result given the growth of our business since
2010,” Mather adds.
The airport’s ongoing environmental initiatives include a A$5
million investment in environmentally friendly ground transport,
including Australia’s first electric airport buses. Late last year a fleet
of six electric buses entered service at the airport, replacing a fleet
of diesel-powered buses, servicing the shuttle route between the
Terminal 2 and 3 precinct and car park. They can carry 70 passen-
gers, have purpose-designed storage racks and have a range of
400km on a single charge.
“ These state-of-the-art electric buses can make up to 100 transfer
journeys on a single charge, providing a clean and sustainable trans-
port option for the one million travellers, visitors and airport workers
who use the shuttle service every year,” says Mather.
The fleet is delivering carbon emission reductions of approximate-
ly 160 tonnes per year and are improving local air quality through
zero tailpipe emissions.
Airports in our region have made remarkable progress
in their journey towards carbon neutrality.
