Smart cities are committed to sustainable and integrated urban development. Digital transformation offers cities, counties and municipalities opportunities for moving towards sustainability and promotes resource-friendly, needs-based solutions for meeting the key challenges of urban development. This Smart City Charter reflects how cities, counties and municipalities in Germany perceive their role in this transformation process. It is intended to help these stakeholders to recognise the opportunities and risks of a future-oriented and responsible urban development at an early stage and to prevent them from taking wrong turns or going down the wrong paths. The charter is also intended to promote inter-communal co-operation as well as the interlinking of high-density and rural areas in line with future-oriented urban and spatial development principles.
