Energy Efficiency

Energy conservation and efficiency are critical issues requiring attention as energy consumption is a major cause of environmental degradation. Given that the planet’s energy supplies of oil, coal and gas are finite, we need to find cost effective ways to reduce energy consumption and environmental damage by developing sustainable energy consumption practices for the future.

Airports use electricity for lighting in the buildings and outdoor areas, as well as for cooling and ventilation of internal spaces. Together with the fuel used in airport vehicles and aircraft support equipment, these constitute some of the major energy usage at airports. Most energy sources produce carbon emissions and can be notable contributors to an airport operator’s greenhouse gas(GHG) inventory.

Water Management

Water is essential for life. Although 70% of the Earth’s surface is covered in water, our planet’s freshwater reserves are scarce, representing only 3 percent of the Earth’s total volume of water. The effects of global warming such as droughts and melting ice caps will further reduce the availability of drinking water.

Water usage also contributes to climate change through the energy consumption that is required to process and treat drinking water.

Waste Management

Waste Management has become one of the most pressing environmental issues. Reducing, reusing and recycling can help reduce the environmental impact by cutting down on the quantity of primary raw material used. Managing waste in a sustainable manner means a diversion away from landfill and incineration to more environmentally preferable options.

Waste produced on Changi Airport grounds is generated mainly from terminal and flight operations, handling maintenance, as well as construction and provision of infrastructure.

Noise Management

Aircraft noise management is an important challenge for airport operators worldwide. The extent to which the community is affected by noise is determined by a wide range of factors including aircraft type, timing of operations, air space management and proximity of noise generating activities.

Noise occurs as a result of airline operations, ground support activities (engine maintenance, re-fueling, baggage loading / unloading and re-provisioning of aircraft), airfield maintenance and site development activities.
