OSLO – Singapore’s Changi Airport Group (CAG) recently released its latest Sustainability Report, “Forging a Sustainable Changi”, outlining the CAG’s sustainability vision, approach, and outcomes, from the financial year ending March 31st, 2022.

The Report & FY2021/2022

The report itself, covers Changi Airport Group’s (CAG) activities across Singapore Changi’s (SIN) four passenger terminals, the aircraft operating areas, and the Changi Airfreight center, in its drive to build a more sustainable Singapore Changi Airport (SIN), with the community and airport partners.

In the FY2021/2022 Sustainability Report, the highlights are as follows:

  • Environment

Changi Airport Group (CAG) is committed to cutting carbon emissions while, in the meantime, improving resource efficiency.

Changi Airport Group is to cap all carbon emissions at 2018 levels until the year 2030, even with the high number of passengers Singapore Changi (SIN) is set to serve in the coming years.

The Changi Airport Group is hard at work towards a “Net Zero” aspiration by 2050, through new technologies and increased adoption of renewable energy.

  • Mapped climate impacts up to 2050

Changi Airport Group is performing a detailed assessment of the impacts of the ever-evolving climate factor. Some of these are greater rainfall intensity and rising ambient temperatures.

The climate risks have been mapped up to 2050 for airport-wide adaptation. With this, solutions are under development to address them.

As an example, as a response to increased rainfall, Changi Airport Group expanded Changi’s (SIN) drainage systems as well as installed sensors for better flood risk management.

  • Decrease in water consumption

Changi Airport Group continues to save on water. Changi Airport reduced the use of non-potable and potable water, such as in toilets or building cooling systems for cleaning and irrigation.

  • More waste diverted from incineration

Changi Airport Group is hard at work in encouraging good recycling practices, as well as implementing more effective waste collection systems.

Changi Airport Group has been able to identify opportunities to use resources efficiently, through collaborations with airport partners, licensed contractors, and cleaners.

These are just some of the many highlights in the FY21/22 report.

The new terminal

As well as renewing its commitment to a much more sustainable airport, Singapore’s Changi International Airport (SIN), recently revealed its design for the long-awaited T5, which is set to handle over 50 million passengers per annum, and strengthen the aviation competitiveness of Singapore.

The new Terminal 5 is set to be the hallmark of a sustainable building, as it is set to be certified by the Building and Construction Authority as a “Green Mark Platinum Super Low Energy Building”.

For more sustainability, rooftop solar panels are to be installed, meaning the terminal will use less energy substituted by reusable energy, with direct cooling and a smart system to control the thermal energy.

Terminal 5 is also set to be able to carry Sustainable Aviation Fuel (SAF), as well as provide fixed ground power for stationary aircraft parked at the gate.


Changi Airport Group’s renewal in the commitment to a sustainable Changi is an important step in reaching the goals they want to achieve.

As we can see, they are already hard at work, and with positive results in hand, things are looking to go in the right direction.
