In this episode, we talk to Ed Mason, Founder & CEO of Jet Zero Australia, who shares insights into the company’s ambitious projects to produce sustainable aviation fuel (SAF) at a commercial scale.
Jet Zero Australia is an Australian bioenergy company that aims to develop the country’s first Alcohol-to-Jet (ATJ) facility for SAF production, using surplus ethanol from agricultural and sugarcane byproducts. Mason discusses Jet Zero Australia’s two upcoming projects: Project Ulysses and Project Mandala, which aim to establish Australia as a major player in the SAF market. Project Ulysses will use LanzaJet’s ATJ technology, to convert bioethanol into SAF and renewable diesel.
Mason provides insights into the strategic choice of Townsville as the location for Project Ulysses, citing factors such as renewable energy availability, proximity to feedstock, and supportive local infrastructure. He also discusses the challenges and opportunities in SAF distribution and the role of the book and claim system in expanding the reach of SAF benefits. Mason also highlights the critical role of partnerships in the SAF industry, with Jet Zero Australia collaborating with major players like Qantas, Airbus, Idemitsu and the Queensland Government.
Delving into the economic impact of SAF production, Mason highlights the industry’s potential for job creation and emphasises the need for continued innovation and collaboration to achieve sustainable aviation goals.

In this episode, we talk to Alejandra Martín Frías, Head of Sustainability Research at FLIGHTKEYS, who shares insights into the company’s research on contrail avoidance and its potential impact on aviation sustainability.
Condensation trails, also known as contrails, are long, thin clouds that often form behind an aircraft in cold and humid conditions when water vapour freezes around small dust and soot particles from the engine. Although they look harmless, contrails are made up of small ice crystals that trap heat in the earth’s atmosphere and contribute to global warming.
Frías delves into the complexities of contrail formation and its impact on climate, highlighting that non-CO2 emissions from aviation may be as significant as CO2 emissions in terms of climate impact. She explains the challenges of implementing contrail avoidance strategies, including weather unpredictability, operational complexities, and the industry’s hesitance to participate in non-CO2 emissions monitoring.
Recently, FLIGHTKEYS was part of a study that simulated contrail avoidance for about 85,000 flights. The study, published in February 2024, analysed two weeks of American Airlines flights in June, and two weeks in January. Frías shares that the study demonstrated significant reductions in contrail energy forcing (up to 73%) with minimal increases in fuel consumption and overall costs (less than 0.11%!).
If you LOVED this episode, you’ll also love the conversation we had with Adam Durant, Founder & CEO of SATAVIA, who shares the groundbreaking work being done in the field of contrail reduction and its implications for the environment. Check it out here.

In this episode, we talk to Brian Moran, Chief Sustainability Officer at Boeing, who shares the company’s multifaceted approach to decarbonising the aviation industry, focusing on sustainable aviation fuel (SAF), innovative technologies, and the importance of regaining trust in the wake of its recent crisis.
Moran discusses Boeing’s Cascade model, an open-source dynamic data modelling tool developed in partnership with MIT, Cambridge, IATA, and NASA, which helps stakeholders make informed decisions about the relative impact of different decarbonisation strategies. He also delves into Boeing’s role in advancing SAF, from de-risking the technology through test flights and research to committing to delivering 100% SAF-compatible aircraft by 2030.
Further, Moran highlights Boeing’s investments in future technologies, such as the electric propulsion flight demonstrator (EPFD) project with NASA and GE Aerospace, and the X-66 demonstrator aircraft featuring a transonic truss-braced wing. He also discusses the company’s involvement in the eVTOL space through their wholly-owned subsidiary Wisk, and how the lessons learned from this venture can be applied to the larger Boeing ecosystem. Moran also acknowledges the challenges Boeing has faced in recent years and emphasises the interconnectedness of safety and sustainability. He views Boeing’s current situation as an opportunity for open, transparent dialogue about the company’s shortcomings and remedial actions.

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.
