Query: Circular City Index: An Open Data analysis to assess the urban
  circularity preparedness of cities to address the green transition -- A study
  on the Italian municipalities   We present a circularity transition index based on open data principles and
circularity of energy, material, and information. The aim of the Circular City
Index is to provide data and a succinct measurement of the attributes related
to municipalities performances that can support the definition of green
policies at national and local level. We have identified a set of key
performance indicators, defined at municipality level, measuring factors that,
directly and indirectly, could influence circularity and green transition, with
a focus on the green new deal vision embraced by the European Union. The CCI is
tested on a open dataset that collects data covering 100% of the Italian
municipalities (7,904). Our results show that the computation of the CCI on a
large sample leads to a normal distribution of the index, suggesting
disparities both under the territorial point of view and under the point of
view of city size. Results provide useful information to practitioner, policy
maker and experts from academia alike, to define effective tools able to
underpin a careful planning of investments supported by the national recovery
and resilience plan recently issued by the Italian government. This may be
particularly useful to enhance enabling factors of the green transition that
may differ across territories, helping policymakers to promote a smooth and
fair transition by fostering the preparedness of municipalities in addressing
the challenge.
