In this first instalment of our two-part special from the C40 World Mayors Summit, Cities 1.5 takes you inside the flagship gathering of the world’s most ambitious urban climate leaders. We hear directly from mayors as they unveil this year’s Offer of Action – a unified commitment that raises the stakes for urban climate leadership and pointedly challenges national governments to match their ambition with action of their own, all on the eve of COP30. We also speak with leading climate experts and C40 partners to explore why cities remain the most effective engines for rapid, equitable decarbonization, and what they must do next to keep the goal of limiting global heating to 1.5°C alive. And crucially, funders share why they’ve chosen to invest in C40’s global network, highlighting the proven impact of coordinated city action and the urgency of scaling it.
