If you think about it, airports are perhaps some of the biggest users of electricity. After all, these are open 24/7, and it takes a TON of electricity to power the terminals and other amenities within an airport.
Here in Singapore, we’re super excited about the newly-opened Jewel Changi (and, of course, Shake Shack and A&W, which are both located within the terminal).
Like the rest of Changi airport, Jewel was built with sustainability in mind, and there are several strategies and tactics that Changi Airport relies on to conserve energy in this terminal and the rest of the airport.
In this blog post, we’ll explore how the world’s top 3 airports (as voted for in Skytrax’s 2018-2019 World Airport Survey) are practising energy conservation, and doing their part to save the environment.
Changi Airport tops Skytrax’s list, and coming in hot on its heels are Japan’s Tokyo Haneda Airport and Seoul’s Incheon Airport. Read on to find out more!
Airport #1: Singapore’s Changi Airport
First up is our very own Changi Airport, which connects customers to over 200 destinations worldwide. In 2018, nearly 66 million passengers flew through the airport, and this number continues to increase. There are plenty of things that Changi Airport does in order to conserve resources and minimise greenhouse gas emissions.
In 2017, for instance, Changi Airport installed 26 common-use charging points to encourage the adoption of electric baggage tractors. Today, Changi Airport’s ground handling partners have largely switched to using electric baggage tractors (as opposed to diesel-powered baggage tractors), and this has saved the airport 627 tonnes of carbon dioxide emissions to date.
On top of that, Changi Airport also utilizes food waste digester systems to convert food waste into liquid using microbes!
These digester systems process an average of 1,100 kg of food waste at Changi Airport daily, and because the airport doesn’t have to send its food waste to incineration plants, this helps it reduce its carbon footprint.
Airport #2: Japan’s Tokyo Haneda Airport
Another airport that’s world-renowned is Japan’s Tokyo International Airport (Haneda). On top of placing second in Skytrax’s list of best airports, this airport also clinched the title of World’s Best Domestic Airport and World’s Cleanest Airport from the same ranking site.
Tokyo Haneda Airport is the third-busiest airport in Asia and the fourth-busiest in the world, and following its expansion back in 2010, it’s now able to handle an impressive 90 million passengers per year.
Now, the airport relies on various tactics to help it reduce its carbon footprint; it even bills itself as an “eco-airport”, which is defined as an airport that “implements measures to conserve the environment and to produce a healthy environment in and around the airport”.
For one thing, air conditioning within the airport is provided only at zones occupied by people. On top of that, the airport recycles its water by using water discharged from kitchens, wastewater generated from terminals and rainwater to power its toilet flushes. The airport also utilizes LED lamps instead of fluorescent lamps, so as to reduce power consumption and CO2 emissions.
Airport #3: Seoul’s Incheon Airport
Last but not least, there’s Seoul’s Incheon Airport, which came in third in Skytrax’s list of best airports in the world, and also won the award for World’s Best Transit Airport.
Incheon Airport opened back in 2001 to replace the older Gimpo International Airport, and has many awards and accolades under its belt. While the airport is currently ranked third by Skytrax, it’s actually been awarded the Best Airport Worldwide for 11 consecutive years by the Airports Council International (ACI)’s Airport Service Quality Award.
To supply power to aircrafts that are parked on the ground, Incheon Airport utilizes Aircraft Ground Power Supply (AC-GPS) instead of the more traditional Auxiliary Power Unit (APU) or Ground Power Unit (GPU).
The AC-GPS method creates 98% less greenhouse emissions as compared to the APU method, and 90% less of the same as compared to the GPU method.
On top of that, Incheon Airport also created an “eco-friendly transportation system” for their employees and other airport users. Amongst other things, this includes an 18.4km bicycle track that connects Incheon Airport and the new city area. The idea is to encourage employees and other airport users to cycle to the airport, instead of taking other forms of transport.
