To strengthen the resilience of HKIA to the emerging impacts of climate change, the Airport Authority (AA) commenced a Climate Resilience Study in February 2020, which will examine HKIA’s capacity to operate despite these impacts. The study will cover the AA’s infrastructure, assets and operations, essential utilities and transport links as well as business partners’ operations. The study aims to adopt a scenario-based approach based on climate data from Hong Kong Observatory and a review of ACI Policy Brief and best practices from airports and local organisations to evaluate the risks and opportunities at HKIA associated with climate change, facilitating decision-making and future planning to strengthen the resilience of the airport.
