In just five years, we've built an ambitious global network of climate leaders, a truly unparalleled community of innovators, policymakers, businesses and changemakers. Together, we are proving that the solutions to our greatest challenges already exist; we just need to back them. At this critical halfway point in the Earthshot Decade, our momentum is unstoppable."
