'But what would

happen if people across the world suddenly stopped flying completely? A

world of no flights would present some serious logistical challenges,

but could also open up the door to huge changes to other, lower-carbon

forms of transport. We are unlikely to ever cut out aviation completely,

and we likely wouldn't want to. But posing this hypothetical question

opens up the door to what we could be doing far more of to reduce

aviation's heavy impact on the climate.'
