Analysis of information sources in references of the Wikipedia article "مسافرت هوایی" in Persian language version.
Almost eight times as many passenger miles are traveled by car as by plane, but passenger car travel only accounts for 3 to 4 times as much greenhouse gas emission.
A large passenger jet may consume five gallons of fuel per mile traveled. Is it possible, then, that planes are more efficient than cars?
if we focus just on the impact over the next five years, then planes currently account for more global warming than all the cars on the world's roads – a stark reversal of the usual comparison. Per passenger mile, things are even more marked: flying turns out to be on average 50 times worse than driving in terms of a five-year warming impact.
