Why Transport & Environment believes aviation’s carbon bill is long overdue
In this episode, we talk to Matt Finch, UK Policy Manager at Transport & Environment (T&E), who shares insights into the challenges and opportunities in sustainable aviation.Finch discusses T&E's role as Europe's leading advocate for clean transport and provides a critical perspective on current efforts to decarbonise the aviation industry. He highlights several key issues:The lack of fuel duty on aviation fuel, which Finch argues artificially suppresses the cost of air travel and hinders the transition to more sustainable alternatives.The UK's Sustainable Aviation Fuel (SAF) mandate, its strengths and weaknesses, and the challenges in scaling up SAF production.The potential of alternative technologies such as hydrogen and electric aircraft, and the need for stronger government support to accelerate their development and adoption.The environmental impact of airport expansion and the need for more stringent conditions on growth.The importance of addressing non-CO2 impacts of aviation, which Finch says account for two-thirds of the sector's overall climate impact.Throughout the conversation, Finch advocates for more ambitious policies and actions to address aviation's environmental impact, while remaining cautiously optimistic about the potential for progress in the sector.If you LOVED this episode, you’ll also love the conversation we had with Hiske Arts, Campaigner at Fossil Free Netherlands (Fossielvrij NL), who explains why climate activists don’t buy the aviation industry’s commitment to addressing climate concerns.

How Kenya Airways plans to unleash the country’s untapped SAF potential
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.As a side note, AviaDev Africa Conference, a crucial platform for improving air travel connections across Africa, is taking place from June 19-21, 2024 in Windhoek, Namibia.
