In this special episode, we bring together Patrick Edmond, Managing Director of Altair Advisory, and Shashank Nigam, CEO of SimpliFlying, to discuss whether aviation demand management is a myth or a necessary component of climate action. Moderated by Dirk Singer, SimpliFlying's Head of Sustainability, the discussion stems from a heated LinkedIn exchange between Patrick and Shashank, sparked by Shashank's reflections after speaking at the World Economic Forum in Davos earlier this year. As the debate gained momentum online, many called for a live conversation – so we decided to host the debate on Sustainability in the Air.The debate covers:The fundamental tension between airline growth ambitions and climate goals, with Shashank sharing insights from his Davos roundtable where aviation CEOs emphasised unfettered growth instead of sustainable growth.The concept of the “guilt premium” versus the “good global citizen premium” in sustainable aviation fuel (SAF) adoption to achieve price parity, with Patrick arguing that systemic policy changes are needed rather than relying on individual airline actions.The relationship between ticket pricing and travel behaviour, and whether raising ticket prices can curb aviation demand.The frequent flyer problem, with a small percentage of travellers accounting for a disproportionate share of emissions, and why a frequent flyer levy is an effective solution.Unexpected silver linings, such as how loyalty program changes might inadvertently encourage more sustainable corporate travel practices.In the end, despite their differing perspectives, Shashank and Patrick found common ground, agreeing that while technological innovation is crucial, broader systemic approaches are needed to address aviation's growing climate impact.If you LOVED this episode, you'll also love the conversation we had with Lee Beck and Thomas Walker of the Clean Air Task Force who discuss the complex challenges and innovative solutions for decarbonising the aviation industry.

In this episode, we speak with Jan Toschka, CEO of Zaffra, a joint venture between Topsoe and Sasol.  Toschka shares insights about scaling sustainable aviation fuel (SAF) production and why he believes the aviation industry must take responsibility for its own decarbonisation rather than relying on other sectors.Toschka discusses:The unique positioning of Zaffra, combining Topsoe's expertise in low-carbon HEFA technology with Sasol's experience in building and operating large-scale gas-to-liquid facilities, positioning them strongly in both renewable and synthetic SAF production.His perspective on financing SAF infrastructure, breaking down the seemingly daunting €250 billion European investment needed by 2050 into more manageable numbers – about €10 billion annually, which could be funded by approximately €10 per passenger across Europe's billion annual travellers.The complementary role of different SAF technologies, with HEFA being the most de-risked pathway currently available, whilst power-to-liquid (PTL) solutions are expected to provide at least 50% of SAF volume in 20-30 years.The importance of both mandates and incentives in driving SAF adoption, with EU mandates helping de-risk demand whilst US incentives under the IRA make investments more manageable. Toschka suggests a combination of both approaches, similar to the UK model, might work best.The strategic approach to SAF distribution, advocating for focused deployment at 20-30 major hub airports initially, supported by book-and-claim systems, rather than attempting immediate widespread distribution across all airports.Toschka emphasises that whilst the aviation industry should pursue multiple decarbonisation pathways including hydrogen and electric aircraft, SAF remains the only viable solution for long-haul aviation in the foreseeable future, and the industry cannot afford to wait for perfect solutions whilst existing aircraft continue operating.If you LOVED this episode, you'll also love the conversation we had with Sarah Ellerby, CEO of Nova Pangaea Technologies (NPT), a UK-based cleantech company that has created a patented technology to enable SAF production from agricultural and forestry waste.

In this episode, we talk to Ali Warrington, Senior Campaigner at Possible, a UK-based climate charity that enables people to take practical action on climate change. Possible has been at the forefront of climate action and has been instrumental in lodging formal complaints against airlines like Virgin Atlantic and British Airways for their greenwashing claims. The charity, along with other climate groups has also taken the  UK government to court over its Jet Zero strategy.Warrington believes that the aviation industry's current approach to sustainability is dramatically insufficient. She points out the limitations of the current decarbonisation solutions – including sustainable aviation fuels (SAF), hydrogen, and electric aircraft – and expresses scepticism about their scalability and effectiveness. She also expresses concern about the enormity of resources, both natural and monetary, that would be needed to make these solutions a reality. Ultimately, Warrington states, demand reduction is the only pragmatic way to cut aviation's share of emissions.Warrington also points out the inequality in air travel in the UK – just 15% of people take 70% of flights annually, with half the population not taking any flights at all. She supports the idea of a frequent flyer levy, to progressively tax individuals on the number of flights they take. She also emphasises the need for a systemic change in global travel infrastructure, and advocates for a shift towards train travel or other low-carbon transportation options, whenever possible. If you LOVED this episode, you'll also love the conversation we had with Hiske Arts, Campaigner at Fossil Free Netherlands (Fossielvrij NL), who discusses the climate activists' scepticism about the aviation industry's commitment to addressing climate concerns.

In this episode, we talk to Akshat Rathi, award-winning senior climate reporter for Bloomberg News. Rathi is the host of Bloomberg's podcast Zero that explores the policies, tactics and clean technologies pushing for a zero emissions future. He is also the author of the book Climate Capitalism, which tracks the unlikely heroes driving the fight against climate change.Rathi argues that for years the aviation industry has sheltered behind the label of being “hard to decarbonise”, which is not only a misconception, but has also stalled the industry's progress towards net zero emissions. He advocates for correctly pricing flights to account for their true environmental cost, a move that could bring an end to “ridiculously” cheap flight tickets.Rathi also discusses the potential of sustainable aviation fuels (SAF) in decarbonising aviation and the need to overcome cost barriers through policy support and corporate commitment. Further, he delves into the role of electric aviation in transforming short-haul travel and regional aviation.In Rathi's view, the aviation industry stands at a crossroads, and the choices made now will determine not just the future of flying, but our ability to meet global climate targets. As he puts it, “We have to start to think about those technologies, because we do need decarbonised solutions.”If you LOVED this episode you'll also love the conversation we had with Dan Rutherford, Senior Director of Research at the International Council on Clean Transportation (ICCT), who shares the latest developments, partnerships, and challenges in reducing aviation emissions and achieving net zero by 2050.

In this episode, we talk to Grace Vihenda, Senior Manager, Innovation and Sustainability at Kenya Airways, who shares the airline's efforts to promote sustainable aviation in Africa, a continent with abundant resources for sustainable aviation fuel (SAF) production but limited infrastructure and investment.In 2023, Kenya Airways became the first African airline to use SAF for an intercontinental long-haul flight. The flight was conducted as a part of SkyTeam's Sustainable Flight Challenge, despite the challenges posed by the lack of a SAF policy framework in the country and the need to purchase the fuel from overseas at a significantly higher cost. The flight has been instrumental in helping chart the course for supportive policy action and the need to set up local SAF production. Vihenda discusses Kenya Airways' plans to scale up local production, with testing and certification planned for 2024, and eventual commercialisation for broader use.Vihenda also elaborates on Kenya Airways' innovative sustainability initiatives, such as partnering with a startup to produce cleaner diesel from waste plastic, implementing 100% recycling of food waste during in-flight meal preparation, and developing upcycled products from aircraft parts. She also emphasises the importance of collaboration and knowledge-sharing among airlines to advance sustainability goals.If you LOVED this episode you'll also love the conversation we had with SkyTeam Alliance's CEO Patrick Roux who outlines the alliance's role in enabling airlines' net zero journey.
