Going green


We take a closer look at a handful of sustainability initiatives at HKG, AMM and SIN airports.


Airport Authority Hong Kong (AAHK) has announced the launch of a renewable diesel pilot project at Hong Kong International Airport (HKG) as part of its ambition to make it the world’s greenest airport.

Hong Kong claims to be the first airport in Asia to use renewable diesel, which can reduce greenhouse gas emission by 87% compared to petroleum diesel, on ground services equipment.

The pilot project is launched in collaboration with Hong Kong Air Cargo Terminals Limited (HACTL) and Shell Hong Kong Limited.

The renewable diesel to be piloted, known as hydrotreated vegetable oil (HVO), is a drop-in fuel fully compatible with diesel engines of equipment such as tractors, rubber removal machines, apron sweeper and mobile generators.

AAHK’s chief operating officer, Vivian Cheung, enthused: “The pilot project marks a significant milestone on our pathway to developing into the world’s greenest airport, achieving our net-zero carbon commitment by 2050 and our midpoint target of 50% reduction in 2035”.


Airport International Group (AIG) and Jordan Water Company (Miyahuna) have formed a strategic partnership to enhance the water infrastructure of Queen Alia International Airport.

The agreement paves the way for a new water pipeline spanning over 11 kilometres from Miyahuna’s Al Qastal substation to the airport, of which 4.6km are outside airport premises and 6.7km are within.

AIG will fund the infrastructure development and Miyahuna will oversee the maintenance and operational management of the pipeline segment situated beyond Queen Alia’s premises.

AIG CEO, Nicolas Deviller, says: “At AIG we are dedicated not only to responsible resource management and environmental stewardship, but also to the success that can be achieved through effective partnerships between public and private entities.”


A new solar photovoltaic (PV) system is to be installed on the rooftop areas of Singapore Changi’s terminal buildings, terminal auxiliary structures, airfield and cargo buildings.

When up and running, the solar PV system will have a combined generation capacity of 43 Mega-Watt peak (MWp), of which 38MWp will be installed on rooftops, making this Singapore’s largest single-site rooftop solar PV system.

The remaining 5 MWp of solar generation capacity will come from a solar PV system installed at a 40,000sqm turf area within Changi Airport’s airfield outside of aircraft operational areas.

This will be the first time a solar PV system is installed in Changi’s airfield – marking the first step towards maximising solar potential at Changi Airport beyond conventional rooftop spaces.

Combined, the rooftop and airfield solar PV systems are expected to generate sufficient solar energy equal to what is needed to power more than 10,000 four-room HDB flats yearly.

With the system, CAG will reduce its carbon emissions by approximately 20,000 tonnes each year, or about 10% of its consumption in 2019.
