Airbus and Paris-based TotalEnergies are to collaborate on research and innovation to develop 100% sustainable aviation fuels for use in current and future generation aircraft as well as address the composition of SAF on the reduction of CO2 emissions and non-CO2 effects, including contrails. TotalEnergies also will supply more than half of the SAF required by Airbus in Europe, extending a partnership which started in 2016 when the energy company began supplying SAF to help power Airbus aircraft deliveries. During the recent Singapore Airshow, Airbus signed an MoU with the Singapore Economic Development Board to facilitate formation of a Sustainable Aviation Hub to focus on technology, research and innovation to progress cleaner aviation, including focus on SAF supply chains and hydrogen-based technologies. Also at the air show Airbus flew an A350-1000 demonstrator jet, the fuel for which included 35% blended SAF.

Milestones in the Airbus and TotalEnergies partnership include provision in May 2021 of French-produced SAF for a Paris-Montreal flight by an Airbus A350, followed in November that year of the first flight of a H225 helicopter, powered by 100% SAF, and the first A321 neo flight with 100% SAF in March last year.

“Accelerating the deployment of sustainable aviation fuels is essential if we are to meet our targets for reducing carbon emissions from aviation by 2030,” explained Airbus CEO Guillaume Faury. “This partnership between Airbus and TotalEnergies demonstrates the willingness of aerospace manufacturers and major energy producers and suppliers to work together to meet this challenge.”

TotalEnergies CEO Patrick Pouyanné said SAF development “is at the heart of our company’s transition strategy. Our company has set itself a target of 1.5 million tonnes of annual SAF production by 2030. We are happy to form a strategic alliance with Airbus to play our part in meeting the challenge of aviation decarbonisation together.”

Airbus has also signed an MoU with the Singapore Economic Development Board to facilitate formation of a Sustainable Aviation Hub to unite aerospace professionals, researchers and innovators in progressing “a robust and environmentally sustainable aviation ecosystem”, extending a partnership between the organisations which started almost two decades ago.

The key focus areas include research and analysis of SAF supply chain and hydrogen-based technologies, projects aimed at modernising and streamlining air traffic management, including the emerging generation of autonomous aircraft, and using new technologies and best practices to advance maintenance, services and operations in the aerospace industry.

A priority for the Hub is to work in close collaboration with local enterprises, universities and research institutions to facilitate knowledge exchange, talent development and joint research initiatives, said Airbus.

“Singapore is home to Airbus’ Asia-Pacific headquarters, given its strategic location, pro-innovation policies, highly skilled workforce and strong research capabilities,” said the airframer’s Chief Technology Officer, Sabine Klauke. “It is therefore an ideal choice to spearhead such an initiative here.”

Jacqueline Poh, Managing Director of the Singapore Economic Development Board, added: “Singapore is partnering with leading aerospace companies to drive technology, research and innovation, and talent development to support the sustainable growth of the aviation industry. The Airbus Sustainable Aviation Hub represents another milestone in Singapore’s longstanding partnership with Airbus.”

Further commitments have been announced by major airlines in Europe and the US for sustainable aviation fuel, collectively totalling around 550 million gallons. Air France-KLM has signed an MoU with its long-term fuel supplier TotalEnergies for up to 800,000 tonnes of SAF, or 264 million gallons, for its group of airlines, while low-cost European carrier Ryanair has partnered with Shell for another 360,000 tonnes, or 120 million gallons, and US operator JetBlue will take at least 92 million gallons of blended product from Fidelis New Energy. The three deals add to other significant offtake agreements this year by each of the airline groups as they ramp up their decarbonisation activities. Meanwhile, Virgin Atlantic is to purchase 70 million gallons of SAF over seven years as part of a new agreement with joint venture partner Delta Air Lines. The fuel, which will be produced by Gevo, will be used on flights from the US West Coast.

The Air France-KLM agreement with TotalEnergies, a strategic partner since 2014, specifies the supply of 800,000 tonnes of SAF over 10 years, with deliveries commencing in 2023. The fuel will be used by Air France, KLM and Transavia largely for flights departing from French airports, in line with national SAF blending requirements, as well as from the Netherlands. The fuel will also comply with the airline group’s policy that any SAF it procures must not compete with human food or animal feed, that it not be derived from palm oil and that it be certified as compliant.

As of earlier this year, KLM flights from Amsterdam Schiphol have been operating with a minimum of 0.5% SAF in their jet fuel and the French government has introduced a 1% SAF mandate on flights from French airports, a level that is expected to rise to 2% in 2025 and 5% in 2030 in line with proposed EU regulation. Crop-based fuels have been excluded from use in the French mandate.

“Air France-KLM is fully committed to advancing SAF production in Europe and around the world,” said CEO Benjamin Smith. “This MoU with TotalEnergies is another building block to further the development of a French SAF industry that can meet the airlines’ needs. This therefore marks a fundamental milestone in the successful decarbonisation of our business. We are continuing to step up our efforts to reduce the impact of our operations as quickly as possible.” 

TotalEnergies is targeting 1.5 million tonnes of SAF production by 2030 using waste and residues including used cooking oil, animal fats and synthetic fuels. “This new partnership with Air France-KLM exemplifies the excellence of industry and French aerospace in committing to a more sustainable aviation sector,” said its CEO Patrick Pouyanné, adding biofuel development was a company priority. “By directly reducing the carbon intensity of the energy products used by our air transport customers, we are actively working with them to achieve net zero emissions by 2050, together with society.”

In recent initiatives, Air France-KLM group airlines have operated a range of flights using between 16% and 30% SAF sourced from TotalEnergies.

The latest SAF deal coincides with confirmation that under the group’s scope 1 and 3 emissions reduction targets, Air France Group and KLM have been assessed and validated under the Science Based Targets initiative (SBTi) as aligning with the ‘well-below 2 degrees Celsius’ objective determined as part of the 2015 Paris Agreement on climate. The strategy is primarily centred on reducing direct and indirect CO2 emissions by 30% per passenger/km by 2030 compared to 2019.

In another European partnership, low-cost carrier Ryanair has signed an MoU with global energy company Shell for the supply of SAF to more than 200 airports across Europe, in particular the airline’s biggest bases in Dublin and London Stansted.

Through this deal, the airline expects to access up to 360,000 tonnes, or 120 million gallons, of SAF between 2025 and 2030, with the fuels produced via multiple technology pathways and using a range of sustainable feedstocks. It estimates that using this amount of SAF would reduce CO2 emissions from its flights by more than 900,000 tonnes, equivalent to the output of over 70,000 Dublin-Milan services.

“SAF plays a key role in our Pathway to Net Zero strategy, and also our commitment to a target of 12.5% SAF by 2030,” said Thomas Fowler, Ryanair’s Sustainability Director. The agreement with Shell would enable the airline to procure around 20% of the SAF needed to meet this target, he said, while progressing its aggressive growth strategy, which estimates that passenger volumes will reach 168 million in FY2023, en-route to a target of 225 million per year by FY2026. 

Jan Toschka, President of Shell Aviation, said their agreement demonstrated that both companies viewed SAF as the key to net zero aviation emissions. “It is fantastic to build on our existing relationship with Ryanair to now look at what we can achieve together on sustainability,” he said. “Leadership and bold actions are needed to accelerate the decarbonisation of flight.”

In the US, JetBlue and Fidelis New Energy (FNE) have signed an MoU on SAF, through which the airline will source at least 92 million gallons of blended product over a five-year term from 2025. The fuel will be designed to achieve negative lifecycle carbon intensity by integrating carbon capture and sequestration (CCS) and biomass energy with CCS (BECCS). The SAF will be produced at FNE’s Gron Fuels GigaSystem at the Port of Baton Rouge, Louisiana, which the company estimates will produce 1 billion gallons per year of SAF, renewable diesel and other low carbon products. The new plant will also use waste process heat to generate power, producing biogas from by-products and using flexible processing methods to produce carbon-negative SAF from existing and emerging feedstocks.

Although JetBlue is already a regular user of SAF, it accounts for less than 1% of the airline’s total fuel usage. “We need significantly more supply to reach our 2040 net zero target,” said Sara Bogdan, JetBlue’s Director of Sustainability and ESG. “With partners like Fidelis and their carbon negative Gron Fuels Gigasystem, we are not only supplying our own growing SAF needs, we’re sending a powerful signal that significant demand for SAF exists. By introducing negative carbon intensity SAF to our network, we are also taking steps towards reaching true carbon neutrality as an airline.”

In addition to producing carbon negative SAF, Fidelis Co-founder and COO Bengt Jarlsjo said his company’s high-capacity carbon sink was expected to permanently sequester some 5 million tons of biogenic CO2 per year from the Louisiana facility.

JetBlue has also had a science-based, Paris-aligned climate target to reduce jet fuel emissions approved by the SBTi. The airline commits to reducing well-to-wake scope 1 and 3 GHG emissions by 50% per revenue tonne kilometre (RTK) by 2035 from a 2019 base year, with a goal of reaching net zero carbon emissions by 2040, 10 years ahead of the sector’s target. The airline said SAF is expected to be the key contributor to large-scale lifecycle emissions reduction, although it is highly dependent on availability and costs of supply.

Virgin Atlantic Airways has announced a 70 million gallon commitment to SAF with its 49% shareholder Delta Air Lines, and to be produced by Gevo. The fuel will be supplied by Delta to Virgin Atlantic at a rate of 10 million US gallons per year over seven years at either Los Angeles or San Francisco airports. It will represent 20% of Virgin Atlantic’s commitment to 10% SAF use by 2030 and equate to around 500 trans-Atlantic flights from Los Angeles.

The parties have not disclosed a start date for deliveries of SAF, which will come from one of Gevo’s future production facilities. Gevo separates sugars and proteins from sustainably farmed non-edible industrial corn, with the sugars then used to produce SAF and the proteins fed to livestock, whose manure can then be processed to develop renewable natural gas and agricultural fertiliser.

“We know that SAF has a fundamental role to play in aviation decarbonisation,” said Holly Boyd Boland, VP Corporate Development at Virgin Atlantic. “The demand from airlines is clear and Virgin Atlantic is committed to supporting the scale up of SAF production at pace. We cannot meet our collective ambition of Net Zero 2050 without it.”

In March this year, Delta signed an agreement with Gevo valued at around $2.8 billion to purchase 75 million gallons per year over seven years, subject to Gevo developing, financing and constructing one or more production facilities to fulfil the quantity.

To coincide with the European Commission’s ‘Connecting Europe by Air: the Green Transformation’, event held in Lyon, France, ten flights operated by six European airlines departed Lyon Saint Exupéry Airport fuelled with a 30% blend of sustainable aviation fuel produced and supplied by TotalEnergies. A number of incoming flights to Lyon followed unrestricted, fully-optimised routings to demonstrate fuel and emissions savings as part of the European SESAR’s ALBATROSS project. As well as the flights, the airlines showcased other sustainability measures including reduced single-use plastics, crew uniforms made from recycled plastic bottles, sustainable catering and offsetting of emissions through certified climate projects, while trade body Airlines for Europe (A4E) promoted the industry’s Destination 2050 roadmap to net zero emissions. Lyon Airport has a goal to become the first commercial airport in France to reach net zero carbon emissions by 2026 within the scope of its business. During a high-level debate at the event, Transport Commissioner Adina Vălean reiterated the EU’s strong support for ICAO’s CORSIA carbon offsetting scheme.

“Despite the current challenges our sector is facing, operationally in the wake of the global pandemic, geopolitically and with rising costs – airlines’ commitment to sustainable air transport is stronger than ever,” said Thomas Reynaert, Managing Director of A4E.

Commenting on the Lyon flights, he added: “Under real operational conditions, we’ve demonstrated that increased SAF uptake and more efficient air traffic management in Europe can reduce CO2 emissions by more than 30% per flight.”

The SAF for the flights was produced from used cooking oil (UCO) at TotalEnergies’ La Mède biorefinery in southern France and, claims the company, reduces lifecycle emissions by 91.2% over its fossil-based equivalent. Briefing reporters at the event, Strategy & Sustainability Development Manager Stéphane Thion said worldwide feedstock supply for SAF was limited and production was reliant on imported UCO, mainly from Asia, and other wastes and fat residues. The transportation of feedstocks from abroad was taken into account when calculating lifecycle emissions reduction, he added.

Thion said SAF production would total around 100,000 tonnes in 2022, with a target of reaching 300 million tonnes, or 65% of total jet fuel consumption, by 2050. A big jump, he admitted, but could be achieved through the twin levers of legislation and incentives to reduce the four to five times price gap, together with the appetite and need by airlines to decarbonise their activities.

Fatima da Gloria, VP Sustainability at Air France-KLM, two of those airlines taking part in the SAF uptake at Lyon, said worldwide SAF supply was very low, given the problem of economic viability and a lack of availability of high-quality feedstocks that were not in competition with food. She thought that in time, bio-based SAF will come closer to price parity with conventional jet fuel but would be restricted by the availability of biomass, whereas advanced non-bio fuels will still be four to five times more expensive by 2030.

“We will need prioritisation of feedstocks for the hard-to-abate aviation sector as it is important to remember that every industry is going through decarbonisation,” she said, echoing the call for government and investor support to boost SAF production and narrow the price gap. She also expressed concerns over EU policies leading to carbon leakage and competitive distortions with airlines outside Europe, but welcomed moves to introduce SAF allowances, which could be granted to airlines through the EU ETS in return for uplifting SAF.

Other airlines taking part in the Connecting Europe industry showcase included Lufthansa, Transavia, Vueling and easyJet. Three of easyJet’s flights departing from Lyon uplifted SAF-blended fuel, with an incoming flight from Lisbon following a specifically designed, optimised flight plan to demonstrate the potential for significant CO2 savings if the Single European Sky was implemented. The flight used airspace normally reserved for military purposes to achieve a direct routing.

The SESAR ALBATROSS project is conducting hundreds of gate-to-gate flight trials across Europe to demonstrate how optimised ATM operations could reduce average CO2 emissions per flight by 5-10% (0.8-1.6 tonnes) by 2035 through enhanced cooperation. Although the Commission has pushed for a Single European Sky, a number of EU member states remain opposed to the move, largely on sovereignty grounds.

“Our airline has committed to net zero by 2050 when we joined Race to Zero last year. We also recently published our ‘35% by 2035’ interim target,” said Thomas Haagensen, Director Group Markets and Marketing at easyJet, who also oversees sustainability at the airline’s board level. “In order to reach this, different elements will play a role and some were showcased on our Lyon flights: we need airspace modernisation –  our SESAR-optimised flight showed what is possible – and we require affordable SAF at scale.

“Full decarbonisation cannot happen without government support, finally implementing the Single European Sky and incentivising new technologies.”

Speaking to GreenAir on the sidelines of the Lyon event, Haagensen said easyJet was supportive of SAF use in helping to reach its net zero target. “But we are quite different from other airlines, in particular the traditional and long-haul carriers,” he added. “For them, SAF is a long-term solution whereas for us, it is an interim solution. We know that by 2035 there will be net zero technology that we can transition to, which is the end game for decarbonisation. With hydrogen and electric for short-haul, we will have that as a feasible option.”

The low-cost carrier is working with a number of industry partners, including Airbus, Rolls-Royce, GKN Aerospace, Cranfield Aerospace Solutions and Wright Electric, to accelerate the development of zero carbon emission aircraft technology and the required infrastructure.

“These technologies are becoming much more tangible. We know they will come and we now need to prepare the supply chain and the infrastructure to make this happen, including the production of green hydrogen,” said Haagensen.

“We are not technology providers – our aim is to acknowledge our impact on the climate, support measures like the EU ETS and stimulate the industry, as we have with startups like Wright Electric. What we can provide is commercial expertise so that they focus on the right segments as well as providing, for example, the flying knowhow of our pilots and helping them to attract more investor funding. We don’t invest our own money but we do invest a lot of our time with them. That’s what our partners ask us for.”

Speaking in a high-level panel debate, EU Transport Commissioner Adina Vălean described the aviation sector as progressive and cutting edge. “There is a clear path to net zero that everyone involved is supporting and I’m sure the industry will achieve it,” she said. “While we will have to wait until 2035 for the disruptive technologies to arrive, sustainable aviation fuels will provide the low-hanging fruit, although we will have to work hard to create a market for them and for the prices to drop. We will also need a more efficient and optimised air traffic system.”

On global aviation issues, Vălean said it was difficult to convince international institutions like ICAO to be progressive. “What is important from my perspective right now, however, is that we must apply CORSIA because this is what we agreed at an international level. If everyone applies it, then it will be a success and we will see a reduction in global CO2. We are also engaged in supporting the international deployment of SAF, even though there are different interpretations of SAF around the world.”

In regard to reaching an agreement on a long-term decarbonisation goal at the ICAO Assembly in the autumn, Vălean said: “We will do our best to convince our international partners to raise the level of ambition. However, we have seen that even if commitments are not being signed, things are happening, for example around SAF, so we have to understand the different approaches on the international stage. We will step up our diplomacy at ICAO though to get a higher ambition agreed and supported.”

The SkyTeam airline alliance has just completed its first Sustainable Flight Challenge, in which member airlines demonstrated or tested initiatives in the air and on the ground to help reduce their carbon emissions, with the results to be shared across the industry. The challenge, which required participants to maximise decarbonisation measures on specific flights between May 1 and 14, attracted 16 of the alliance’s 18 members, and delivered outcomes including services part-powered by large volumes of sustainable aviation fuel and weight-saving operational measures such as the use of new, lightweight aircraft tyres. The concept of the Sustainable Flight Challenge was developed by The Bold Moves, a group of employees within SkyTeam member airline KLM, who were inspired by a 1934 air race between London and Melbourne, designed to demonstrate the possibilities of long-range commercial flights. SkyTeam adopted the KLM idea and expanded it to encourage all its member airlines and partners to participate, reports Tony Harrington. Meanwhile, SkyTeam member Saudia has undertaken what it claims is the world’s longest net positive flight through a carbon offsetting partnership with CarbonClick and aviation consultancy SimpliFlying.

“The climate crisis is the greatest challenge facing our industry, and there’s no time to lose,” commented SkyTeam on the Sustainable Flight initiative. “As airlines, we need to reshape the future of air travel for generations to come. Together, we are committed to further reducing our carbon footprint by finding new ways to cut emissions, make our fleets more efficient and better care for the world we connect. We’re challenging ourselves to innovate, reaching for new heights to find as-yet undiscovered solutions that we can put into practice across our industry.”

As originator of the Sustainable Flight Challenge, KLM operated two flights from Amsterdam as part of the project, one a Boeing 787-10 widebody service to Edmonton, Canada, the other an Embraer E190 regional jet to Porto, Portugal, each incorporating more than 50 efficiency measures, including a 39% blend of sustainable aviation fuel. Weight-saving initiatives included the use of artificial intelligence modelling to predict the amount of water needed for each flight, lightweight cargo pallets and nets, and optimised aircraft loading to ensure the best centre of gravity, to improve flight aerodynamics and reduce fuel burn by 1.5-2%. Pilots also collaborated with air traffic controllers to identify the most efficient air routes, while on the ground, business class passengers were asked to pre-select meals in order to minimise uplift of catering which would not be used, while transport companies delivering freight were asked to use vehicles powered by electricity or biodiesel fuel.

Air France also operated two flights part-powered by SAF, and performed with new, more fuel-efficient jets – an Airbus A350 from Paris to Montreal, using a 16% SAF blend produced by TotalEnergies, and an Airbus A220 from Paris to Lisbon with a 30% SAF mix, both well above the mandatory 1% blend required on all flights from France, and aligned with the airline’s target of 30% less CO2 emissions per passenger kilometre by 2030, compared to 2019. The airline said both flights were also supported by initiatives including single-engine taxiing and optimised routes, each achieving CO2 reductions of close to 45% compared to routine services. It foreshadowed greater use of AI to optimise flight paths, and use of autonomous tractors to help decarbonise baggage transport at airports.

In the US, Delta Air Lines used a Boeing 737-900ER – the most fuel-efficient aircraft type in its fleet – to operate a sustainable flight from its Atlanta home base to Salt Lake City. The plane was part-powered by 400 gallons of SAF, provided by Gevo, and the largest volume of sustainable fuel uplifted on a flight from Atlanta. The aircraft was also equipped with new main landing gear tyres which reduced weight by 100 pounds (45kgs), while at both ends of the journey the flight was serviced by 100% electric ground equipment used to transport baggage and fuel. Delta has pledged that 25% of its ground service vehicle fleet will be electrically powered by the end of 2022, up from 20% now, and rising to 50% by the end of 2025. Other features of its sustainable flight included recyclable packaging for beverages and no disposable plastic.

Another SkyTeam member, Saudi Arabian Airlines (Saudia), as part of the Sustainable Flight Challenge, has claimed the world’s longest net positive flight through a carbon offsetting partnership with New Zealand-based CarbonClick and aviation consultancy SimpliFlying. The airline said 346 tonnes of carbon emissions were offset from a six-hour, Boeing 787-9 flight between Jeddah and Madrid. The flight also incorporated the first in-flight ‘sustainability lab’, in which passengers contributed suggestions on how to reduce the environmental impact of flying.  To offset the flight’s emissions, CarbonClick will apply the airline’s contributions to the generation of wind-powered electricity in India, enabling wind turbines to be powered for 26 days, and delivering sustainable electricity to communities in Bhuj, in the western state of Gujurat.

SkyTeam said the pressures presented by Covid-19 meant that not all of the alliance’s member airlines could participate in the inaugural Sustainable Flight Challenge but expressed confidence that more would join in future years, with outcomes shared not only across the alliance, but further afield. “The industry as a whole will benefit from the challenge,” said SkyTeam. “That’s because everything we learn we will share open source. It’s our commitment to finding new ways to reduce our industry’s footprint and bring the future of sustainable air travel forward. What’s more, we hope to broaden participation in years to come.”

Two new European-Japanese industrial partnerships have been formed to progress the transition of Japan’s air transport sector to sustainable fuels. Paris-based TotalEnergies has joined with Tokyo-based ENEOS Corporation to conduct a feasibility study into the production of sustainable aviation fuel at the latter’s Negishi Refinery by 2025, while aircraft manufacturer Airbus has signed a memorandum of understanding (MoU) with Japanese industrial group Kawasaki Heavy Industries to collaborate on the production of hydrogen fuel, its delivery to airports and its supply to aircraft. The announcements coincided with the release of a new study by global business consultancy McKinsey which highlighted increased global concern by air passengers about aircraft carbon emissions, and growing evidence that travellers were prepared to pay higher fares to help cut aircraft emissions, though only 2% in Japan were willing to do so, reports Tony Harrington.

Energy companies TotalEnergies and ENEOS said they were considering a joint venture to produce up to 300,000 tons of SAF per year from waste cooking oil or animal fats, and had commenced a study of feedstock procurement for the project, which aligns with a target set by Japan’s Ministry of Land, Infrastructure, Transport and Tourism for 10% SAF use by 2030. The partnership would leverage the experience of TotalEnergies in feedstock procurement and SAF production technology, and the production, loading and unloading facilities at the ENEOS Negishi Refinery, which is close to Tokyo’s Narita and Haneda airports, which together comprise Japan’s largest market for aviation fuel.

A joint statement to announce the collaboration said TotalEnergies was “pursuing its strategy of building a multi-energy company with the ambition to get to net zero by 2050”, while ENEOS Group’s long-term vision to 2040 “is contributing to the development of a decarbonised, recycling-oriented society”, through which the company “aims to provide a stable supply of the various forms of energy required to meet the needs of the times.”

The MoU signed by Airbus and Kawasaki is focused on preparation of a hydrogen-fuelled ecosystem, from production to plane. The companies will address challenges and develop an advocacy plan to support aviation’s hydrogen requirements, with specific focus on the establishment of airport hydrogen hubs.

Stephane Ginoux, Head of North Asia Region for Airbus and President of Airbus Japan, said the partnership with Kawasaki would “accelerate and promote” the ambitions of the Japanese government to decarbonise aircraft operations by 2050, adding: “We strongly believe that the use of hydrogen, both in synthetic fuels and as a primary power source for commercial aircraft, has the potential to significantly reduce aviation’s climate impact.”   

Dr Motohiko Nishimura, Executive Officer and Deputy General Manager of Hydrogen Strategy Division, Kawasaki, said: “We have specialised in the development of infrastructure for liquefaction, transportation, storage and transport to receiving terminals, contributing to the construction and expansion of supply chains for the hydrogen market.” He expressed confidence that Kawasaki’s technology would connect hydrogen production and consumption areas, via a new ‘Hydrogen Road’.

As it has in similar collaborations in New Zealand, South Korea and Singapore, Airbus, a leading advocate of hydrogen propulsion, said it would provide aircraft characteristics, fleet energy usage and insight on hydrogen-powered aircraft for ground operations, while Kawasaki has committed to provide supply chain technology and infrastructure deployment scenarios to supply targeted airports.

Meanwhile, global business consultancy McKinsey has released details of new research that indicates greater awareness by air passengers of aviation’s impact on the environment, but vastly varying levels of commitment to help reduce emissions. McKinsey said that in 11 of the 13 countries in which air travellers were surveyed, “emissions are now the top concern of respondents”, well up on a 2019 survey in which those concerns were highest in just four markets.  

However, it also found that the attitudes and preferences of air travellers varied significantly between markets, with just 2% of respondents in Japan indicating they were willing to pay to help achieve carbon neutral flights, contrasting with some 60% of Spanish respondents and 9% in India supporting the idea.

At a global level, McKinsey’s survey revealed that almost 40% of air travellers globally were now willing to pay at least 2% more for “carbon-neutral tickets”, or $20 for a $1,000 roundtrip, while 36% of survey respondents indicated they would take fewer flights to help reduce their own impact on the environment. But while the survey revealed greater awareness of aviation’s impact on the environment, it found travellers still prioritise price and connections over sustainability in booking decisions.
