SAF. Future Fuels. Hydrogen. Electric. Hybrid. Aviation contributes approx 2-3% of global CO2 emissions, with the majority being from aircraft movements. But how bad could it get? And what steps are being taken - and how quickly - by governments, regulators, airlines, aircraft manufacturers and airports to reduce emissions at scale? To address these big issues, Gary welcomes back to the show Shantanu Gangakedkhar, Senior Consultant, Aerospace & Defense, at Frost & Sullivan. Shantanu recently wrote a White Paper called Sustainable Technologies in Aviation, and speaks at aviation conferences worldwide. Decarbonising our skies is complex, and will require an entire turnaround of the airline and airport sectors. It will also incur costs that will be passed onto travellers. But how quickly can governments and regulators push through mandates to speed up progress? And, the big question, is Net Zero by 2050 actually achievable? A fascinating deep dive into the critical issues around air travel, air pollution and climate impact.
