This article shares the strategy for mainstreaming the Sustainable Development Goals (SDGs) at the University of Valencia (UV), which, although limited in its scale, may compel other Higher Education Institutions to think in technological and social progress aligned with the 2030 Agenda. It explicates a process driven by the UV, on the occasion of the 75th anniversary of the United Nations (UN), and in collaboration with the Service for Geospatial, Information, and Telecommunications Technologies from the UN Support Base in Valencia (Spain) to prepare the online event: ¿The United Nations We Want¿. It was the culmination of a collaborative project between students and faculties from different scientific, technological, social, legal, humanistic, and health disciplines that structure the University of Valencia. The intention was that new generations experience the role they can have to shape the future we want, while the university community as a whole can become part of transformative institutional change that draws on both top-down and bottom-up strategies in pursuit of Education for Sustainable Development.
