About This Podcast
Aviation has many paths to net zero, and few are straightforward. Sustainability in the Air cuts through the noise with clear, expert-led conversations on what’s actually advancing a more sustainable future for flight in one of the hardest sectors to decarbonise.
💚 Twice a month, SimpliFlying CEO Shashank Nigam speaks with airline, airport, travel, and energy leaders to unpack the decisions shaping aviation’s climate future.
💚 Each month, our Head of Sustainability Dirk Singer adds a Signal episode spotlighting the tech founders building aviation’s next wave of climate innovation.
Whether you work in aviation, advise it, or simply care about the future of travel, this podcast is for you.
