The objectives are: to scale up and increase the visibility of regional sustainability services, to raise awareness and create a community through nudging by developing methods and tools for nudging a community for regional sustainability services, and, to initiate and foster international collaboration and knowledge transfer of smart city initiatives. The project will provide the proof-of concept for a replicable online marketplace using behavioural nudges and gamified features. It will focus on bike mobility services, local production and consumption and digital inclusion services.
