COP30 was billed as the “COP of Truth”: the moment the world would finally stop sketching climate plans and start delivering them. Set in the heart of the Amazon, the summit carried huge symbolic and political weight.

Expectations were high; urgency even higher.

Across two tense weeks, progress did happen: on finance, adaptation, forests, and the new Just Transition Mechanism.

But the headline story was what didn’t make it into the final text: any mention of fossil fuels at all.

After 30 COPs, the world still couldn’t name the main source of emissions, leaving a sense of frustration hanging over an otherwise productive summit.

Join David Carlin and Simon Messenger as they break down what moved forward, what stalled, and what COP30 means for the road to COP31 and for the future of a global process struggling to keep up with a fast-warming planet.
