The most emissions-efficient U.S. airline, according to Cirium: Frontier
Frontier Airlines is the most efficient carrier in North America and the second most efficient in the world, according to a new emissions calculation methodology developed by the airline industry data company Cirium. Frontier, with carbon dioxide emissions of 54.4 grams per available seat kilometer in 2024, was beat out only by Hungarian discount carrier Wizz Air, which emitted 53.9 grams of CO2 per seat kilometer last year, according to the Cirium analysis. As a point of comparison, lifecycle emissions of a simple cup of black coffee are 21 grams of carbon, according to CarbonClick, with emissions sometimes ballooning to many times more than that depending upon cultivation techniques, the type of cup used and whether the coffee is consumed with cream or other additives. Among the world's 10 largest airlines, as measured by total seat miles offered, Ryanair was the top emissions performer, emitting 63 grams of CO2 per available seat kilometer. The four U.S. carriers among the top 10 largest airlines ranked second through fifth respectively, with Southwest leading the way, followed by Delta, American and United. Southwest was the clear efficiency winner among those U.S. behemoths, with emissions of 68.9 grams per available seat kilometer. The other three were bunched closely together, emitting between 74.4 and 75.4 grams of CO2 per seat kilometer. How the ranking is calculated Cirium joins several entities that have developed methodologies for measuring aviation and airline carbon emissions, including Google, IATA, the International Civil Aviation Organization (ICAO), the U.K.'s environmental department DEFRA and Cirium's competitor, OAG. But Cirium says its platform, called Emerald Sky, is the first to use real-time flight tracking data for its calculations instead of relying on projected or standard routes or forecasted route averages. To achieve its emissions estimates, the platform also considers actual air time and atmospheric conditions of a flight; aircraft and engine types; aircraft age; seating configurations; passenger loads; cargo loads; and taxi times. An airline's usage of sustainable aviation fuel (SAF) is not yet considered in the Emerald Sky formula because SAF accounts for only a tiny fraction of total jet fuel. Cirium chief strategy officer Kevin O'Toole said the company will include SAF in the algorithm once its accounts for 1% of global fuel consumption, which is about double its current contribution. Cirim said the methodology had been independently reviewed and validated by PricewaterhouseCoopers and by the Rocky Mountain Institute, a Boulder, Colo.-based environmental nonprofit. Why low-cost carriers are more CO2-efficient Overall, the Cirium Flight Emissions Review showed that dense seat configurations and modern fleets are airlines' primary levers for efficiency. All the 10 most efficient carriers have a low-cost model. Frontier achieved its second place ranking largely through its combination of densely configured cabins and a fleet that averages just four-and-a-half years of age. The other U.S. airline in the top 10 is low-cost carrier Spirit, with a fleet-age average of 6.3 years of age. Full-service airlines, which offer first and business class cabins, tend to have higher emission on an available seat kilometer basis. "Seat density and fleet age matter more than almost any other factor airlines can control," chief Cirium marketing officer Mike Malik wrote. "While industry leaders are succeeding through these operational strategies, it also highlights how limited the levers for emissions reductions really are compared to the scale of the challenge." The airline industry has pledged to achieve net-zero emissions by 2050.

What Makes an Airline 'Emissions-Efficient'? See the Top 10 Rankings
Some airlines are becoming more efficient, but overall emissions are still growing as the sector grows. The bigger picture is how fast aviation is expanding, and what that means for the climate. Wizz Air has been named the most emissions-efficient airline in a new climate ranking from aviation analytics firm Cirium. The Hungarian low-cost carrier emits around 54 grams of CO₂ per seat per kilometer, according to the review, which was verified by PwC and is the first of its kind in the industry. That efficiency measure is driven by several key factors, starting with Wizz Air's relatively young fleet. The airline's planes average around four years old, and many are up to 25% more fuel-efficient than older aircraft. Seat configuration plays a role too. Low-cost carriers typically cram more seats into each plane, which reduces emissions per passenger. One often-overlooked detail: how long a plane spends taxiing on the ground. That process can at times account for as much as 20% of a flight's total emissions. Cirium's ranking lists airlines that are moving to newer generation aircraft. Total Greenhouse Gas Emissions Not Accounted For However, the ranking does not account for total greenhouse gas emissions or the use of sustainable aviation fuel (SAF), which the industry says could cut a flight's carbon footprint by up to 80%. Wizz Air, for example, is still one of Europe's most polluting airlines. It's also among the fastest-growing, with over 70 new planes on order. Since 2019, Wizz Air's total emissions have nearly doubled, from 3,734,556 tonnes in 2019 to 7,962,308 tonnes in 2024, according to a report from Transport and Environment and the airline's own sustainability data. Yvonne Moynihan, the group's ESG officer, previously told Skift that the rise in emissions is linked to the airline's rapid growth under its 'WIZZ500' strategy, which aims to double the fleet by 2033. 'This growth contributes to higher overall emissions,' she said. 'But we emphasize carbon intensity per passenger-kilometer as a more relevant metric for assessing environmental impact.' Moynihan acknowledged that reducing emissions while expanding is a significant challenge and that deeper cuts will depend on scaling up SAF, which is still barely used across the industry. 'We are actively pursuing fleet renewal and operational efficiency,' she said. 'But broader reforms are needed across the industry to ensure success.' Cirium excluded SAF from its 2024 analysis because it currently makes up just 0.53% of global aviation fuel use. 'SAF still emits CO₂,' said Jeremy Bowen, CEO of Cirium. 'But today it makes up a very small fraction of fuel use. In the future, if SAF use ramps up, it will be taken into account.' How Airlines Ranked Cirium ranked airlines by CO₂ emissions per seat per kilometer in grams. Here are the top performers: Wizz Air: 53.9 grams of CO₂ per seat per kilometer Frontier Airlines: 54.4 Pegasus: 57.1 Volaris: 57.9 IndiGo: 58.2 Jetstar: 58.4 Spirit Airlines: 58.4 Scoot: 58.7 SunExpress: 59.4 Air India Express: 60.5 Another Cirium list looked at the largest airlines in the world by passengers. It then ranked them by emissions-efficiency. Ryanair: 63 grams of CO₂ per seat per kilometer Southwest Airlines: 68.9 Delta Air Lines: 74.4 American Airlines: 74.6 United Airlines: 75.4 Turkish Airlines: 76.9 China Southern: 78.2 Qatar Airways: 79.7 Air China: 83.3 Emirates: 84.9 Cirium told Skift that while the ranking allows for fair comparison between airlines of different sizes and fleet types, it doesn't capture the full picture, such as the total emissions growth of airlines or the climate impact of individual companies.
