This week, we recorded live from London Climate Action Week at the Mission 2025 launch event. Tom Rivett-Carnac was joined by guests Andrew Steer (Bezos Earth Fund), Adair Turner (ETC), Isabelle Noero (Earthrise), Hein Schumacher (Unilever), Tamsin Ballard (PRI), Karen Pflug (INGKA Group) and Nigar Arpadarai (COP29 Champion). Hear their conversations about how to act on climate with speed and scale.

Moving faster on tackling the climate crisis is too difficult, too unpopular or too expensive, right? Wrong! This week a new high-ambition coalition of business, mayors, investors, health leaders, athletes, youth activists, scientists and citizens was launched to call on governments to move even faster on climate action. Over 20 organisations have joined Mission 2025, to say: "We are ready to embolden governments to set more ambitious plans and accelerate implementation. We know this can unlock trillions in private investment to protect our nature, scale cheap renewable energy, support industries to compete in a low carbon economy, and safeguard living standards equitably for our people." Mission 2025 is a much needed effort to unlock the momentum needed for this transition to happen at the speed and scale required, and with the equity deserved. Because holding the line on 1.5°C is not an aspirational target – it is a scientific imperative.
