In Search of Indicators for Assessing Smart and Sustainable Cities and Communities' Performance

The goal of the paper is to elaborate on sustainability aspects of smart sustainable urban environments. More specifically, at a first step the paper aims at critically reviewing globally initiated state-of-the-art approaches for assessing smart cities' performance as to sustainability objectives. The scope of this effort is to identify sets of indicators used in different approaches as well as convergence/divergence among them. Secondly, an attempt to integrate different indicator sets into a more enriched and coherent indicator system is carried out which, by effectively embedding smart and sustainable city development into sustainability indicators' sets, can be used by various types of cities' examples. Finally, the rationale of the indicators' selection process is depicted, in order to support policy makers and planners' guidance towards choosing an appropriate, city-specific set of sustainability indicators for carrying out relevant assessments.
