World’s greenest airlines unveiled11 March 2011
The study of airline efficiency was conducted by Atmosfair, a carbon offsetting company, and looked into factors such as how efficient an airline’s fleet was and how full its planes normally fly.
Monarch was judged the world’s most efficient airline, with Atmosfair praising its efficient aircraft and high seating density.
German carrier Condor, owned by holiday giant Thomas Cook, won second place thanks to its high occupancy and Canadian Air Transat was ranked third, making it the most efficient long-haul carrier.
Some of the world’s better-known airlines fared less well, with Emirates in 30th place, Delta in 33rd, Air France in 37th, Lufthansa 52nd, British Airways in 61st, American Airlines in 63rd and Virgin Atlantic in 99th place.
