In addition to the climate goals of aviation, there are other directly environmentally relevant topics. For example, the immediate vicinity of the airport is affected to a greater extent by aircraft noise. More than 1,400 take-offs and landings per day were counted in 2019 in Frankfurt am Main. This creates noise as a local immission that affects the environment. For this reason, studies on topics like “technical possibilities for reducing noise on aircraft” are carried out.
Airplanes also emit aerosols. There is still a great need for research, as their sources, transport, and effects have not yet been fully investigated.
The sustainable operation of the airport also plays a special role: emission-free ground traffic, energy efficiency, waste management. Together with partners, strategies are being developed to make airports climate-neutral and sustainable for the future. An essential element of sustainable mobility is the area of intermodality of flight, rail and road at the airport transport hub.
