Carriers meeting at the annual Airlines for Europe (A4E) Summit in Brussels called on policymakers to “supercharge” the production of sustainable aviation fuels across Europe through the introduction of competitive tax credits and the funding and support for nascent, emerging and established SAF projects or fuel producers. It is crucial that Europe supports affordable and reliable domestic production, they said in a “call to action”, particularly in the face of significant market pressure from global players outside of Europe. Meanwhile, A4E member Lufthansa Group has reported more than one million passengers have opted for its Green Fares tickets, which includes a provision for SAF offsetting, one year after their launch. European renewable fuels producer Neste has started supplies of blended SAF at Schiphol under an agreement with Emirates, while Sasol and Topsoe have launched their new joint venture Zaffra, located in Amsterdam, that will focus on SAF development and delivery.

At the forefront of A4E’s “call to action” is what it describes as “competitive decarbonisation” in a global market, to ensure Europe is a world leader in aviation’s net zero transformation.

“The next few years provide a real opportunity for change and we are setting out how we want to future-proof flying,” said A4E Managing Director Ourania Georgoutsakou at the opening to the trade body’s Summit in Brussels. “We are today making a pledge to improve the future of flying but can only do this if policymakers make the vital changes to support our decarbonisation efforts, providing real airspace reform, ensuring our sector remains competitive and completing a true single aviation market.”

A4E member airlines have been involved in a number of SAF commitments this month. International Airlines Group (IAG), made up of Aer Lingus, British Airways, Iberia and other carriers, signed a 14-year agreement with US startup Twelve for the supply of 785,000 tonnes of e-SAF, the groups biggest single SAF deal to date and the first e-SAF procurement by a European airline group (see article).

Following its purchase of 500 tonnes of SAF from Austrian energy company OMV last year, Ryanair reported it would take an additional 500 tonnes in 2024. Under an MoU between the two companies, Ryanair has access to purchase up to 160,000 tonnes of SAF during the period to 2030.

Another A4E member, AEGEAN, which first flew with SAF in 2021, is to expand its use of SAF under an agreement with Shell and MOH Aviation, who will supply a “significant” quantity of blended SAF at Stockholm Arlanda and London Heathrow airports. The Greek carrier said this marked the beginning of a gradual expansion of its SAF uplift programme, “where available”, throughout its entire network.

According to Lufthansa Group, an average of 3% of passengers have used its Green Fares tickets, with the tickets being selected by 11% of business class travellers via the Lufthansa Group portals. In total, travellers have offset around 77,000 tonnes of CO2. Offsetting of flight CO2 emissions is through SAF as well as by a contribution to high-quality climate protection projects. The group ensures the amount of SAF required for offsetting is fed into the airport infrastructure within six months of purchase.

Green Fares are available with Lufthansa, Austrian Airlines, Brussels Airlines, SWISS, Edelweiss, Discover Airlines and Air Dolomiti on more than 730,000 flights per year within Europe and to Morocco, Algeria and Tunisia. The group has been testing Green Fares on selected long-haul routes since November 2023.

Meanwhile, Finland-headquartered Neste has launched Neste Impact for businesses looking to reduce the carbon footprint of their air travel and transport activities. The solution is aligned with the Science Based Targets initiative (SBTi), enabling businesses to credibly report achieved emission savings and follows a book-and-claim approach. The related emission reduction achieved is third-party verified and further validated through the ISCC SAFc registry. Neste ensures the SAF is supplied to a partner airline and the purchased amount is verifiably used to replace fossil fuel.

UAE carrier Emirates has activated its fuel agreement with Neste at Amsterdam Schiphol and 2 million gallons of blended SAF will be supplied into the airport’s fuelling system over the course of 2024. The blended SAF will comprise over 700,000 gallons of neat SAF. The airline will track the delivery of SAF into the fuelling system and the environmental benefits using standard industry accounting methodologies.

Global chemicals and energy company Sasol and Danish carbon emission reduction technology specialist Topsoe have launched their joint venture, named Zaffra, which will be based in Amsterdam. The partners say the new company, to be headed by former Shell Aviation boss Jan Toschka, aims to advance SAF production and technologies.

Alaska Airlines is partnering with Microsoft Corporation and carbon technology company Twelve to progress the development of power-to-liquid (PtL) fuels, through which carbon dioxide captured from the atmosphere is converted with renewable energy to create sustainable aviation fuel. The three companies have signed a Memorandum of Understanding that will lead to the first commercial demonstration flight in the US using Twelve’s E-Jet low carbon fuel, followed by Alaska’s use of the fuel to part-power some of Microsoft’s business travel on the airline to help recompense its emissions. Alaska Airlines has committed to achieving net zero emissions by 2040, 10 years ahead of the airline industry’s generally-agreed commitment to 2050, and has purchased and promoted SAF for more than a decade, while Microsoft is also an investor in Twelve through the Microsoft Climate Innovation Fund, reports Tony Harrington. Meanwhile, two European airlines, Aer Lingus and Aegean, have announced SAF deals.

Diana Birkett Rakow, SVP Public Affairs and Sustainability for Alaska Airlines, said the carrier’s commitment to achieving net zero emissions by 2040 relied upon procuring SAF, including Twelve’s E-Jet product. “We are committed to making SAF more widely available, at an affordable price, helping bring new alternatives to market, and using these fuels in our operation, a path that requires public policy action and private partnerships like this one,” she said. “We’re excited to work with Twelve and Microsoft to advance Twelve’s E-Jet fuel, turning captured CO2 and renewable energy into fuel for our airplanes.”

The airline said that since 2010, it had worked with a range of public and private partners “to advance public policies needed to jumpstart the nascent SAF market, create new offtake agreements and cultivate partnerships to accelerate market development,” and was a founding member of the Aviators Group of the Sustainable Aviation Fuel Buyers Alliance (SABA), which was announced at last year’s COP26 climate summit in Glasgow. Alaska Airlines has also participated in Boeing’s ecoDemonstrator programme to test 100% SAF in one engine of a Boeing 737 jet, partnered with SAF provider SkyNRG to progress development of fuel from recycled municipal waste and is a participant in two US-based SAF procurement deals by the oneworld alliance, of which it is a member. Beyond SAF, it has partnered with ZeroAvia to help develop a hybrid-electric powertrain for regional airliners.

Twelve’s E-Jet fuel is created through the use of an electrochemical reactor and a proprietary catalyst, which replicate the natural process of photosynthesis at industrial scale by electrifying CO2 and water to produce carbon neutral fuel. “By producing our drop-in E-Jet fuel from captured CO2 we can rapidly and efficiently close the carbon cycle and allow businesses to sustainably use emissions to power their own business travel,” said Nicholas Flanders, CEO and Co-founder of Twelve. “Partnering with progress-minded brands like Alaska Airlines and Microsoft adds thrust as we work towards delivering industrial-scale volumes of E-Jet.” The company said the fuel had already been tested and qualified by the US Air Force.

In March this year, the Canadian e-commerce group Shopify, which is also one of the largest corporate investors in long-term carbon removal, announced its Sustainability Fund had made the first purchase of Twelve’s E-Jet fuel. “Purchasing carbon removal from leading companies is critical to helping them scale, but purchasing from emerging companies pursuing novel approaches is equally essential,” said Stacy Kauk, Shopify’s Head of Sustainability. As well as helping to accelerate carbon removal solutions, she added, such investments also provided recipient businesses with a strong revenue stream and helped them to secure financing for their programmes.   

Elizabeth Willmott, Carbon Programme Director at Microsoft, said addressing emissions from hard-to-abate sectors such as aviation needed commitment from all stakeholders. “Building on our Climate Innovation Fund investment in Twelve and relationship with Alaska Airlines, this collaboration provides an opportunity to accelerate decarbonisation in the aviation industry by exploring how to use low carbon fuels produced by renewable electricity, like Twelve’s E-Jet.”

While Alaska Airlines expands its extensive SAF programme to include PtL, two European airlines, Aer Lingus and Aegean, have both announced new agreements to purchase SAF in line with their commitments to achieve net zero emissions by 2050.

Aer Lingus, a member of International Airlines Group (IAG), has just signed an agreement to purchase 19,000 tonnes per year of SAF for five years from US-based renewable fuels company Gevo, commencing in 2026. The fuel will be used by the airline to help power its flights from Los Angeles and San Francisco, and from 2026 will represent 50% of the fuel purchased by Aer Lingus in California.

IAG, which also includes British Airways, Iberia, Iberia Express, Vueling, Air Nostrum and LEVEL, has already committed to a target of net zero emissions by 2050, and to powering 10% of its flights with SAF by 2030. Aer Lingus said its deal with Gevo would provide enough SAF to cut lifecycle CO2 emissions by at least 180,000 tonnes, equivalent to 1,000 net zero CO2 flights with widebody Airbus A330 jets between Dublin and Los Angeles.

In Greece, Aegean has announced its first SAF deal, a partnership with Hellenic Petroleum to use a blended product to operate flights on domestic and international routes, beginning with departures from its hub at Thessaloniki Airport, to be followed soon after by services from Athens International Airport. Timing of the programmes was not revealed.
