What does a technical roadmap to sustainable aviation look like, and what role will innovative technologies, sustainable aviation fuels, and new propulsion methods play in this transformation? We explore the costs, timelines, and infrastructure changes needed, and consider how these shifts could reshape not just the industry, but our global approach to climate resilience.

Britain's first astronaut, Helen Sharman, is joined by Professor Christer Fureby. Christer is a professor at Lund University in Sweden, specialising in computational fluid dynamics, with a focus on sustainable energy solutions. With extensive expertise in advanced propulsion systems and sustainable aviation, his research aims to improve the efficiency of energy use and to reduce the climate impact of aviation.
