Today, we're sharing a preview from another podcast from the Financial Times, Tech Tonic. Does aviation have a sustainable future? As more people fly, aviation is on track to becoming a much bigger problem for climate change. Tech Tonic host Pilita Clark, FT columnist and climate journalist, looks at the potential for a more sustainable aviation industry, a sector that’s struggled to come up with new technology to cut its emissions. Could we end up being forced to cut back on flying altogether? Producer Josh Gabert-Doyon travels to Farnborough Airshow, and we hear from Zero Petroleum’s Paddy Lowe, Boom Supersonic’s Blake Scholl, and executives from Boeing, Airbus, ADS, United and EasyJet. Check out stories and up-to-the-minute news from the Technology team at ft.com/technology and Climate team at https://www.ft.com/climate-capital  Presented by Pilita Clark. Edwin Lane is senior producer. Produced by Josh Gabert-Doyon. Executive producer is Manuela Saragosa. Sound design by Breen Turner and Samantha Giovinco, with original music from Metaphor Music.
