New report outlines Changi’s sustainability vision and targets

Changi Airport Group (CAG) has released its latest sustainability report, ‘Forging A Sustainable Changi’, which outlines its sustainability vision, approach and outcomes from the financial year ending 31 March 2022.

The report covers CAG’s activities across Changi Airport’s four passenger terminal buildings, the Changi Airfreight Centre and the aircraft operating areas on the airport site to build a sustainable Changi Airport with airport partners and the community.

Environmental highlights of the FY2021/2022 Sustainability Report include:

Committing to cutting carbon emissions while improving resource efficiency. It has pledged to cap absolute carbon emissions at 2018 levels until 2030, even with the growing number of passengers that Changi Airport is expected to serve in the years ahead.

It notes that it strives towards a Net Zero aspiration by 2050 through the use of new technologies and the increased adoption of renewable energy.

The airport operator has also embarked on a detailed assessment of the impacts of evolving climate factors, such as rising ambient temperatures and greater rainfall intensity.

Climate risks are mapped up to 2050 for airport-wide adaptation and solutions are being developed to address them. For instance, in response to increased rainfall, CAG has expanded Changi’s drainage network and installed sensors linked to a real-time data dashboard for better flood risk management.

Apart from improving chiller condensate and waste water recycling capabilities, CAG continues to save water and has reduced the airport’s overall water consumption by 5.9%. The airport has, for example, reduced the use of potable and non-potable water, ranging from toilets and building cooling systems to irrigation and cleaning.

And CAG claims to have optimised waste management by reducing waste at source, encouraging good recycling practices and implementing effective waste collection systems.

Indeed, close collaboration and communication with licensed contractors, airport partners and cleaners have enabled CAG to identify opportunities to use resources more efficiently.

It notes that projects embarked on over the past year included the up-cycling of building materials and composting of horticultural waste.
