The operation and development of HKIA gives rise to a range of environmental impacts. Many of these are directly measurable and, taken together, represent the ‘environmental footprint’ of HKIA. We collaborate with our business partners and the aviation industry, and adopt a systematic ‘airport-wide’ approach to manage, reduce and mitigate the airport’s environmental footprint, with particular focus on the management of solid waste, carbon and energy management, and biodiversity.
