Speaking about stastistics on the link above. Here's one that doesn't add up to me:
Shortening routes can indeed significantly reduce CO2 emissions. In fact, every minute of flying time knocked off a journey saves 62 litres of fuel and 160kg of CO2 emissions. And everyone arrives sooner!
This was taken from the FAQ 'most direct route'.
Surely a saving of 62 litres of fuel couldn't possibly result in a saving of 160kg of CO2. Wouldn't 62 litres of fuel weigh about 50kg pre-combustion?
