What is the greenest airline

These airlines are the most damaging to the climate

Flying is the most damaging form of locomotion. According to a survey by the German climate protection organization Atmosfair, only one in ten airlines worldwide keeps its CO2 emissions constant despite growth. The "Atmosfair Airline Index 2018" (AAI) compared the more than 190 largest airlines worldwide and assessed their CO2 efficiency.

In a ranking, the “Atmosfair Airline Index 2018”, which the German climate protection organization Atmosfair presented recently, each airline can receive between 0 and 100 efficiency points, separated into short, medium and long-haul flights. Low-cost airlines are rated in their own class in the AAI. The index is based on the CO2 emissions of an airline per kilometer and passenger on all flown routes, as stated in the Atmosfair press release.

The 10 losers in the "Atmosfair Airline Index 2018"

The following ten airlines performed worst in the overall ranking in the "Atmosfair Airline Index 2018":

  1. South African Airlink (South Africa) with 2.3 efficiency points in efficiency class G (125th place)
  2. Egyptair Express (Egypt) with 25.4 efficiency points in efficiency class F (124th place)
  3. Kenya Airways (Kenya) with 27.6 efficiency points in efficiency class F (123rd place)
  4. Envoy (USA) with 28.2 efficiency points in efficiency class F (122nd place)
  5. Delta Connection (USA) with 28.5 efficiency points in efficiency class F (121st place)
  6. TAP Express (Portugal) with 30.6 efficiency points in efficiency class F (120th place)
  7. United Express (USA) with 31.1 efficiency points in efficiency class F (119th place)
  8. Mahan Air (Iran) with 33.9 efficiency points in efficiency class F (118th place)
  9. Air Astana (Kazakhstan) with 34.8 efficiency points in efficiency class F (117th place)
  10. Virgin Australia Regional (Australia) with 36.0 efficiency points in efficiency class F (116th place)

Measures for the climate change in air traffic required

According to Atmosfair, one in ten airlines worldwide is keeping its CO2 emissions constant despite growth. These few airlines almost compensate for the increase in the number of kilometers flown by increasing their CO2 efficiency. According to Atmosfair, this is a first step on the way to the goals of the Paris Climate Agreement, which calls for rapid and far-reaching CO2 reductions worldwide. In terms of absolute climate efficiency, however, these airlines are only in the upper mid-range.

The few growing airlines with constant CO2 emissions include Thai Airways (67 out of 100 points, efficiency class C), Finnair (64 points, class D), American Airlines (59 points, class D) and All Nippon Airlines (58 points, class D). "Our results show that the efficiency increases of the airlines worldwide do not lead to the 1.5 degree or 2 degree target alone at the moment," says Dietrich Brockhagen, Managing Director of Atmosfair. "We need new, synthetically and CO2-neutrally produced fuels and further measures for the climate change in air traffic."

Higher CO2 efficiency through modern aircraft

The Atmosfair Airline Index shows that new aircraft such as the Boeing 787-9, Airbus A350-900 or A320neo can achieve values ​​of less than 3.5 liters of kerosene per passenger and 100 kilometers on long-haul flights. According to Atmosfair, these new aircraft are currently setting the bar significantly higher for achievable CO2 efficiency. As a result, airlines that had an unchanged fleet or could have improved only a little with new aircraft did worse in the current ranking. However, since, according to Atmosfair, no such new aircraft dominated the fleet of any airline, no airline achieved the best efficiency class A and only two achieved efficiency class B.

Holiday fliers are ahead in the ranking

As in the previous year, the British TUI Airways (formerly Thomson Airways) is in first place in the Atmosfair ranking with almost 80 percent of CO2 emissions. Fourth place goes to the German sister Tuifly (78 out of 100 efficiency points). With Condor, another German holiday airline made it into the top 10 (72 out of 100 efficiency points).

Here are all ten winners of the "Atmosfair Airline Index 2018":

    • 1st place: TUI Airways (UK) with 79.3 efficiency points in efficiency class B.
    • 2nd place: LATAM Airlines Brasil (Brazil) with 78.8 efficiency points in efficiency class B.
    • 3rd place: China West Air (China) with 77.8 efficiency points in efficiency class C.
    • 4th place: TUIfly (Germany) with 77.6 efficiency points in efficiency class C.
    • 5th place: Transavia.com France (France) with 76.3 efficiency points in efficiency class C.
    • 6th place: SunExpress (Turkey) with 74.9 efficiency points in efficiency class C.
    • 7th place: Thomas Cook Airlines (UK) with 74.7 efficiency points in efficiency class C.
    • 8th place: Air Europa Express (Spain) 73.4 with efficiency points in efficiency class C.
    • 9th place: Condor Flugdienst (Germany) with 71.8 efficiency points in efficiency class C.
    • 10th place: Juneyao Airlines (China) 70.9 efficiency points in efficiency class C.

The best values ​​are achieved by airlines that use modern aircraft adapted to the length of the route, accommodate many seats in them and make good use of both seats and cargo space, as the press release from the climate protection organization Atmosfair continues.
