Exclusive | Operate a quieter plane, get more flight slots at night: Hong Kong encourages airlines to fix noise pollution
Trial scheme focuses on non-environmentally friendly and noisy planes – instead of just restricting flights at night

Airlines in Hong Kong are being encouraged to use cleaner and quieter aircraft in return for the chance to operate more flights at night.
A trial is under way for airlines flying out of Hong Kong International Airport to phase out older planes, as such flights contribute to noise pollution – a serious issue at night for nearby residents.
As an incentive, compliance will be rewarded with opportunities to operate more late evening, overnight and early morning flights. The scheme looks to focus on the cause of pollution problems rather than restricting aircraft movements, aviation authorities say.
“The overarching objective of the quota count scheme is to encourage airlines to use more environmentally friendly aircraft at Hong Kong’s airport,” a spokeswoman for the Civil Aviation Department said.
