The Swiss Aviation Infrastructure Sectoral Plan (PSIA) sets a binding framework for air traffic in the form of a “noise framework” which includes:
Genève Aéroport has committed to reducing the area exposed to aircraft noise by 20% by 2030.
We encourage airlines, through financial incentives, to favour next-generation aircraft.
These aircraft have a lower carbon footprint. For example, Airbus A320neo aircraft are on average:
We continuously monitor noise emissions from the airport 24/7 through our SIMBA network, consisting of five monitoring stations installed in neighbouring municipalities.
Connected to radar and operational data, it enables us to:
All data are publicly available and can be accessed online.

We introduced a noise quota system on 1 January 2025 to encourage airlines to reduce late departures after 10 p.m. Once quotas are exhausted, night departures are subject to a highly dissuasive fee.
The system was tested in 2024. The results were positive: the number of departures after 10 p.m. decreased by 36.2% compared with 2023. In 2025, the formal implementation of the system led to a further 24.6% reduction in departures.
Since 2016, engine run-ups for large aircraft are no longer carried out outdoors but in a noise buffer facility. Smaller aircraft carry out their engine tests in another hangar built in 1985.
We launched a building soundproofing programme in 2003 for properties located near the airport.
Since 2004, 4,483 homes (719 buildings) have been soundproofed, for a total investment of CHF 67.93 million.
