Meanwhile, the HKIA’s “Renewable Diesel Pilot Project” got the top award in ACI’s Green Airports Recognition 2025, in the category of over 38 million passengers per annum. Organized by the ACI Asia-Pacific & Middle East, the award recognizes airports with outstanding performance in environmental protection.

The Hong Kong airport became the first airport in Asia to use renewable diesel on ground services equipment through the “Renewable Diesel Pilot Project”, which was launched by Airport Authority Hong Kong (AAHK).

The renewable diesel used in the pilot is hydrotreated vegetable oil, which is fully compatible with diesel engines in equipment such as baggage tractors, rubber removal vehicles, airfield sweepers and mobile generators.

Speaking about the recognition, AAHK Chief Executive Officer Vivian Cheung Kar-fay said, “These remarkable achievements are a testament to the tireless efforts of all airport staff, who enable HKIA to maintain world-class service standards and continuously expand our extensive air network and intermodal connectivity."

The awards reinforce Hong Kong’s position as an international aviation hub while fulfilling its social responsibility to protect the environment, she added.
