Does low cost mean low emissions? Without going so far as to present low-cost airlines as paragons of sustainable transport, aviation consultant Cirium gives low-cost airlines the thumbs up in its Flight Emissions Review study. This recently published report ranks airlines according to the carbon emissions of passengers per seat-kilometre flown. Its Top 20 most efficient carriers in this respect include the following in the top three places Hungary's Wizz Air, American Frontier Airlines and Turkey's Pegasus<\/strong>. Just behind them are Mexico's Volaris and India's IndiGo. Transavia is also at number 13e<\/sub> as well as Canadian carrier Air Transat (15e<\/sup>) and the Greek scheduled airline Aegean (16e<\/sup>). And, of course, Ryanair rounds off the top 20.<\/p>\n\n\n\n

This study is based on data from its EmeraldSky solution, launched by Cirium last year in partnership with the start-up RouteZero. offer companies precise measurements<\/strong> on the impact of their business travel by air, this platform uses a methodology that takes into account the weight of flights, the time spent taxiing and in flight, and the fuel model to determine the consumption of a flight and its emissions per passenger. But it does not include the incorporation of sustainable aviation fuel - SAF - in this analysis.<\/p>\n\n\n\n

The report also highlights the performance of airlines by type of flight, whether intra-regional or long-haul. For intra-European flights, Wizz Air, Aegean, Transavia and Ryanair are logically the best ranked, but the top 10 also includes scheduled airlines such as TAP Air Portugal, Finnair and SAS<\/strong>. As for intercontinental flights, those crossing the Atlantic saw a French airline come out on top: French Bee. Air Tahiti Nui came in at number 6.e<\/sup> position, just behind TAP Air Portugal, but ahead of Aer Lingus, JetBlue, Air Canada and LOT. Transpacific flights, behind low-cost carrier Zipair Tokyo, airlines such as LATAM, Air Canada, Delta, Aeromexico and Hainan Airlines.<\/p>\n\n\n\n
