The first step in the initiative for system demonstrators for climate-neutral cities was Viable Cities and Vinnova's call #11 System demonstrators for climate-neutral cities, design phase. The design phase, which has already been completed, was open to the first nine cities that signed Climate City Contract 2030, and was available in spring 2022. The ambition was that the system demonstrators would strengthen the cities' ability to accelerate the transition to becoming climate neutral by 2030.
Six projects were supported in the call, aiming to develop ideas and proposals for system demonstrators, mobilize stakeholders, identify barriers and deepen the understanding of the system. The project duration was September 2022 to February 2023.
