Are flights across the world about to be grounded? Is a terrible war about to create an unlikely good news story for the climate? As conflict in the Middle East threatens the Strait of Hormuz, jet fuel shortages are forcing aviation to confront a structural vulnerability it has spent decades avoiding.

This week, Tom Rivett-Carnac, Christiana Figueres and Paul Dickinson examine what the shortage reveals: aviation's near-total dependence on fossil fuels, the structural reasons it has proved so hard to break, and whether it’s ever going to be possible to fix.

They speak with Karel Bockstael and Roxanne van Rijn, former aviation insiders who co-founded Call Aviation to Action, a movement designed to reach the industry’s senior leaders and push for much-needed change. They explain why kerosene remains the only viable option for long-haul flight, how thin margins trap airlines into opposing the very regulation they need, and why this fuel shock may be the scarcity event that finally forces the model to shift.

Could this crisis become aviation’s turning point? And in a world where up to 80% of people have never set foot on a plane - and 1% account for half of all aviation emissions - what would a truly fair future for flight actually look like?
