> My 55-minute flight from Geneva to Zurich didn't land on its first attempt.
I know this is not the point of the article but why would you take a flight from Geneva to Zurich? It's less than 3h by train, which if you count the time it takes to get to Geneva airport and go through security, probably becomes a much smaller difference.
And for that, you're emitting ~100kg of CO2 [1]
