ITU-T Recommendations

Supplement 46 to the ITU-T L-series Recommendations aims to provide the definition and conceptualization of the circular city, identify the terminology that deals with circular city, define these terms and uncover the recent trends of circular cities, based on the systematic literature review and bibliometric analysis. Circularity in cities appear to be more than the sum of the multiplication of urban circular economies and has increasingly become the subject of policy innovations, urban strategies, and research and development agendas. However, the concept of circular city and the terminology that deals with it remains unclear, regardless of the emerging scientific and political attention that it gains.
The main elements examined in this Supplement are:
– The definition of circular cities;
– The determination of a conceptual architecture of circular cities;
– The identification of recent trends in a circular city.
