Large variation found in airlines' CO2 emissions

Lufthansa and BA two thirds as fuel efficient as Norwegian Air Shuttle, says report by group that exposed VW emissions-rigging scandal

There is huge variation in fuel efficiency between transatlantic airlines, with British Airways and Lufthansa emitting 51% more carbon dioxide than the cleanest flyers, according to a report by the organisation that revealed the VW test-rigging scandal.

Pollution from a non-stop transatlantic round trip averages around one tonne of CO2 per passenger, the International Council on Clean Transportation (ICCT) research found - the same as would be clocked up in a year by commuting 22 miles to work daily in a Toyota Prius.
