Climate change isn’t going to solve itself. The crisis of refugees, migrants, and displaced people is not going to solve itself. In this time of rapid change, decreasing trust in public institutions, and numerous existential threats to our societies, museums need to do more than ‘engaging audiences’. To live up to their missions and to the social contracts that give them visibility and resources in communities, museums and institutions of all kinds need to take responsibility for building a bridge between knowledge of difficult challenges and action towards overcoming them. Action, and positive change, are central to the concept for the Museum for the United Nations — UN Live, a newly forming global institution headquartered in Copenhagen, Denmark. The museum’s mission, “to connect people everywhere to the work and values of the United Nations and catalyze global effort towards accomplishing its goals”, was deliberately composed to ensure the institution places people and outcomes — particularly those related to the UN’s Sustainable Development Goals — at the center of its work and responsibility.
