20. The case for traveling by air, after all
The narrative about aviation's impact on the climate is muddled by a desire to use moral ammunition. Trains can never substitute airplanes on long distances, air traffic is crucial for global integration and there is no point in knocking out aviation anyway — its share of the world’s CO2 emissions is too small. If all the billions that are invested in trains instead were to be invested in clean aviation, we would soon have it. The railway boom is a side track. This essay was originally published on Medium.
