The Global Innovation Summit 2025, a key event in the run-up to COP30, will focus on strategies to create more sustainable and inclusive cities. Hosted in Rio de Janeiro, Brazil, the summit brings together urban leaders, investors, and policymakers to discuss a critical challenge: securing the trillions of dollars needed for new infrastructure in a rapidly urbanizing world. With a special emphasis on blended finance models, the summit aims to bridge the gap between public and private capital to fund projects in transport, energy, and housing, especially in the Global South. Sessions will explore how digital innovations can build smarter cities and how to strengthen urban resilience through climate-smart infrastructure.
