Everyone knows that flying is not good for the environment. But often there is no other way to get to our target destination. Now I ask myself how environmentally unfriendly flying really is.
Air traffic is responsible for 2.5% of total Co2 emissions. This does not sound like much, but if it were a country, it would be the 5th largest emitter in the world.
The route from Munich to Frankfurt by plane causes CO2 emissions of 140 kilos, whereas the same route by train only causes emissions of 17 kilos.

Flight radar before and during Corona:

It is clear that there was a decrease in flights due to Corona. In March 2020, there was a clear decrease of 75% in air traffic compared to the previous year (2019).
At times, Swiss parked almost its entire fleet of aircraft at the airport Dubendorf to save costs.

Here you can see where my partners live. They live in the romanian city Buzau.
