The ad read: 'Because we operate Europe's most modern fleet, our planes emit 30% fewer emissions per passenger mile than traditional airlines.' The ASA ruled it was likely to mislead, as easyJet could not prove newer planes had 30% fewer emissions per passenger mile. Instead, the claim was based on the airline being able to carry more passengers per plane than traditional rivals.
EasyJet was told not to repeat the claim. The firm said the ad was a one-off.
