MOVE 21 is a four-year Horizon 2020 Innovation Action that started in May 2021, focusing on the transition to zero-emissions and climate-resilient transport systems. Central to the integrated approach of MOVE21 are three Living Labs in Oslo, Gothenburg and Hamburg, and three Replicator Cities: Munich, Bologna and Rome. In these urban nodes, different types of mobility hubs and associated innovations are tested, and means to overcome barriers for clean and smart mobility are deployed.
