Carbon calculator: taking one flight emits as much as many people do in a year

Flying consumes around 2-3 litres of fuel/100km so it's about twice as efficient as driving the distance alone in a car. Problem is that too many people want to (and can) go to the other end of the world too often.

It's not really that linear because taking off and landing both consume significant "flat" amounts of fuel.

Also, fuel consumption is exponential with distance, for reasons similar to the rocket requestion.

Wikipedia has a cool graph:

That graph is not 0-based, so it is very misleading.

Indeed. 7500nm generates only about 10% more CO2 than 2500nm. Not exactly what I was expecting from 'exponential'.

If you're looking for fuel efficiency, a more apt comparison would be with trains rather than cars.
