Changi Airport Group (CAG) has released its latest Sustainability Report, ‘Forging A Sustainable Changi’, which outlines CAG’s 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 in its drive to build a sustainable Changi Airport with airport partners and the community.
Highlights of the FY2021/2022 Sustainability Report include:
Zero carbon growth until 2030, capping absolute carbon emissions at 2018 levels
CAG is committed to cutting carbon emissions while improving resource efficiency. CAG will 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. CAG strives towards a Net Zero aspiration by 2050 through the use of new technologies and the increased adoption of renewable energy.
CAG’s inaugural climate resilience study mapped climate impacts up to 2050
CAG 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.
5.9% decrease in overall water consumption
Apart from improving chiller condensate and wastewater recycling capabilities, CAG continues to save water. Changi has reduced the use of potable and non-potable water, ranging from toilets and building cooling systems to irrigation and cleaning.
11% of waste diverted from incineration
CAG optimises waste management by reducing waste at source, encouraging good recycling practices and implementing effective waste collection systems. Close collaboration and communication with licensed contractors, airport partners and cleaners have enabled CAG to identify opportunities to use resources more efficiently. Projects embarked on over the past year included the upcycling of building materials and composting of horticultural waste.
