Norwegian airline green, British Airways less clean: study

British Airways' fleet, including this  747 landing at Heathrow Airport on February 18, 2015, is among the least fuel-efficient

A Norwegian low-cost airline has been dubbed a champion of fuel efficiency in a new study released Tuesday, in marked contrast to British Airways and Lufthansa which have been labelled as among the worst.

The study by the International Council for Clean Transportation (ICCT) found that three of the least fuel efficient carriers were BA, Lufthansa and Scandinavian airline SAS, who between them account for some 20 percent of the transatlantic air travel market.

Top of the heap in the study of 20 major non-stop transatlantic carriers was Norwegian Air Shuttle which burned 51 percent less fuel per passenger kilometre than BA.

Air Berlin and Ireland's Aer Lingus came in second and third in the study, which the ICCT said was intended to provide greater insight into the fuel efficiency, and therefore carbon intensity, of international flights.

The study, which comes ahead of a Paris conference on climate change due to start November 30, showed Norwegian Air Shuttle, the world's seventh-largest low-cost airline, averaged 40 passenger kilometres per litre of fuel.

By comparison, Germany's second-largest airline Air Berlin had a fuel efficiency of 35 passenger kilometres per litre.

It was the US-based ICCT which helped to uncover the pollution cheating scandal at German auto giant Volkswagen in September after it tested actual emissions figures for diesel cars and found some Volkswagen models to be above permitted limits.

Noting the fuel efficiency disparities between the carriers, ICCT said seat configuration was a key factor in the results and that the average fuel burn of the aircraft used was also significant.

It also noted that first class and business class seats accounted for around a third of carbon emissions but only 14 percent of overall seats.

"The very high of Norwegian Air Shuttle demonstrates the central role of technology in reducing CO2 emissions from the aviation sector," the ICCT concluded.

"Airlines that invest in new, advanced aircraft are more fuel-efficient than airlines that use older, less efficient aircraft."
