Qantas is worst major airline for fuel efficiency and emissions in the Pacific: study

Qantas has been ranked in a new study as the worst major airline for fuel efficiency and carbon emissions when flying across the Pacific.

The International Council on Clean Transportation (ICCT) has analysed the fuel emissions of 20 major airlines conducting trans-Pacific flights, ABC reports.

It ranked Qantas the worst in 2016, finding it burned on average 64 per cent more fuel per passenger-kilometre than the top ranked airlines, China-based Hainan and Japan’s ANA.

A “passenger-kilometre” is defined as how many people you can fly 1 kilometre on 1 litre of fuel.

The other major Australian carrier, Virgin Australia, was ranked sixth in the study — only 6 per cent below the top performers.

The study suggested Qantas’s fuel efficiency was poor on its Pacific flights because it used four-engine planes on those routes, such as the Boeing 747 and Airbus A380, which consume more fuel than twin-engine planes.

The carrier also did not pack the planes to capacity, with passenger numbers averaging 74 per cent of available seats, and its freight taking up a much smaller proportion of weight than better-performing airlines.

Qantas said the study was not an accurate representation of its fuel efficiency across the Pacific, and it had a number of fuel-efficiency programs in place.

The study has been published by the ICCT, which is the same group that exposed the Volkswagen emissions scandal.

Co-author and aviation expert Dr Dan Rutherford said the council conducted the study because they wanted environment-conscious consumers to be able to make informed decisions when choosing an airline.

“The average flyer has very little information about the carbon footprint or the environmental performance of airlines,” he said.

“There’s a big gap in fuel efficiency on trans-Pacific flights, this leads to excess carbon emissions and we really hope that people start to think about this as they make their travel decisions.”

Greenhouse gas emissions by the global aviation industry makes up about 2.5 per cent of the world’s carbon pollution.
