Aircraft use petroleum-based fuels to generate the energy needed to fly.

In addition to the not insignificant noise pollution, the pollutants emitted by their engines also pollute our environment and living space. The areas around airports are particularly exposed to these pollutants.

In addition, their fuel consumption is much higher than that of other means of transport in general, in relation to the volume of passengers carried.

The high CO2 and water emissions from aircraft are a major contributor to the greenhouse effect.

The various nitrogen oxide compounds emitted by aircraft engines contribute to the thinning of the ozone layer, which filters out harmful radiation from the sun.
