Airports are an important link for national and international transportation infrastructure. Airport infrastructure can include a variety of facilities and operations, including runways and taxiways, aprons for boarding and deboarding passengers and loading and unloading cargo, ground handling and terminal buildings, air traffic control, airport security and fire-fighting services, airline and freight companies, aircraft maintenance, fuel storage and distribution facilities, facilities for heat and power supply, wastewater and storm water management facilities, and waste collection and storage. Improved economic, social and environmental sustainability is becoming a critical factor in a country’s airport expansion and operation plans. Airport operations can result in environmental negative impacts, including noise and vibrations, storm water and wastewater, fuel and hazardous materials management, solid waste, air emissions, and energy and water consumption. Significant efforts have been made to improve air transportation operations and make them environmentally sustainable. This helps reduce environmental impacts, maintain high and stable levels of economic growth, and promote development consistent with the needs and values of the local community. Examples include incorporating environmental sustainability in airport master planning, improvements in noise and air emission reduction and control, alternative materials for chemical de-icing, improved storm water management design and water reuse, and enhancing wildlife protection.
