• Our Sustainability Approach

    Emissions Management

    Changi Airport Group has committed to Zero Carbon Growth until 2030, with absolute emissions to be capped at 2018 levels even as we continue to grow our business. We actively explore ways to improve the building energy efficiency of our terminals, as well as increase the share of renewables in our energy mix.

    We also work closely with our airport partners to support their decarbonisation efforts both in the air and on the ground, through initiatives such as supporting the uplift of Sustainable Aviation Fuel and enabling the electrification of ground support equipment.

    Waste Management

    At CAG, we optimise 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 our resources more efficiently.

    We also promote circularity in our operations, such as recycling concrete in the rehabilitation of aircraft parking stands and composting horticultural waste.

    Water Management

    We adopt a water optimisation strategy to reduce water consumption and increase water usage efficiency. We reduce our use of potable and non-potable water across all areas, ranging from toilets and building cooling systems to irrigation and cleaning.

    For example, our toilets are retrofitted with water-efficient fittings. We have leakage reporting and repair management systems to ensure timely fault reporting. At our airport nurseries, rainwater is also harvested for irrigation purposes. 

    Climate Resilience

    Changi Airport is a critical component of Singapore’s infrastructure. We ensure long-term resilience against climate change through early planning, so as to minimise potential vulnerabilities and operational continuity risks.

    We have developed risk thresholds and mitigation measures in the following five focus areas:-

    • Increasing rainfall intensity
    • Rising sea levels
    • Higher ambient temperatures
    • Increasing lightning frequency
    • Wind speed and direction
