Terra50 is a new annual initiative launching this year within the Smart City Expo World Congress (Barcelona), the leading global event for cities, developed in collaboration with Tomorrow.City.
Terra50 is focused on identifying and showcasing 50 innovative solutions addressing today’s most pressing climate challenges in cities. The goal and relevance of Terra50 lie in making current urban dynamics visible and translating them into an accessible format that enables replication by partners in multiple cities.
Conceived as a long-term platform aligned with the 2050 horizon, Terra50 is designed to evolve through annual editions, continuously updating and expanding its selection as urban challenges intensify and new solutions emerge.
The initiative is driven by a team specialized in innovation exploration, with a cross-cutting perspective that is not limited to a single sector. It brings together knowledge and practices from different fields and applies them to urban climate challenges. This approach enables the identification of relevant solutions, making them understandable and connecting them to real urban needs, acting as a bridge between what already exists and what cities urgently require.
Terra50 covers a broad spectrum of urban transformation areas, including enabling technologies; energy and other vectors such as water management, nature-based solutions, materials and waste; mobility; infrastructure and building; governance and economy; living and inclusion; and the blue economy. These areas reflect the systemic nature of the transformation cities must undergo, where digital infrastructure, energy systems, built environments, governance models, and social dynamics are deeply interconnected.
Rather than being a report or a static collection of case studies, Terra50 is conceived as a living and accessible platform that translates existing knowledge into action. By curating real, implemented cases from around the world, it aims to make innovation tangible, transferable, and adaptable, enabling cities, organizations, and professionals to learn from what works and explore new applications in different contexts. Ultimately, Terra50 seeks to act as a catalyst for connection and change, linking proven solutions with urgent challenges and contributing to the acceleration of more resilient, sustainable, and inclusive urban systems.
