Qantas Airways has been ranked by the International Council on Clean Transportation as the least fuel-efficient airline on transpacific operations in 2016, burning an average of 64% more fuel per passenger-kilometer than the most efficient operators, Hainan Airlines and All Nippon Airways (ANA). With an average fuel efficiency of 22 passenger-kilometers per liter of fuel (pax-km/L) – that is, one litre of fuel carries one passenger 22 km - Qantas was 41% below the industry average.
The ICCT report compares the fuel efficiency of 20 airlines operating nonstop flights between the mainland United States and East Asia and Oceania.
According to the report, Hainan’s efficiency rating mostly reflected its very advanced fleet, as 81% of its available seat kilometers were aboard Boeing 787 Dreamliner aircraft. ANA, in contrast, operated aircraft with higher fuel burn but carried more payload, especially cargo. ANA carried about three times as much belly freight per passenger as Hainan, equaling 48% of total payload carried.
Qantas recorded poor fuel efficiency because it operated the most fuel-intensive aircraft at very low load factors for both passengers and freight.
Aviation fuel efficiency and industry emissions are reported on every three years by the the UN body for aviation, the International Civil Aviation Authority (ICAO). The most recent Environmental Report – On Board, a sustainable future – outlines developments in the adoption of the global Aeroplane Carbon Dioxide (CO2) Emissions Certification Standard, and provides an overview of industry progress towards the stated goal of achieving carbon-neutral growth from 2020. This target was essentially dependent on the uptake of sustainable alternative fuels and, to a lesser extent, aircraft design and construction.
The analysis showed that in 2020, a reduction of 1.3 per cent of international aviation CO2 emissions could be possible from the use of sustainable alternative fuels. By 2050, 100 per cent of international aviation jet fuel demand could be met with alternative fuels.
