This document proposes the creation of a global leadership platform called u.school. The u.school will engage leaders across sectors, cultures, and generations to address societal challenges through innovation. It will use awareness-based practices and multi-stakeholder collaboration. The u.school will include global networks of hubs, leadership programs, and "innovation labs" focused on areas like food, health, education, cities, and banking. Its goals are to build collective leadership capacity, generate new solutions through prototyping, and create systemic change toward resilience and well-being for all.
