Dubai International Airport

Hong Kong International Airport (HKG) officially opened its long-awaited Terminal 2 on May 27, marking a major milestone in the airport’s HK$141.5 billion (US$14.5 billion) expansion project aimed at strengthening its position against regional rivals Singapore Changi Airport (SIN) and Dubai International Airport (DXB).

A new policy brief from ODI Global has placed Dubai International Airport (DXB) and London Heathrow Airport (LHR) at the top of the world’s highest-emitting airports, with the 20 largest contributing 27.3% of total aviation CO2 emissions in 2023.
