2. These innovation solutions address the following urban dimensions:

a. People: in terms of discovering and meeting today and future generations'
requirements;
b. Living: by enhancing quality of life and social coherency, as well as efficiency regarding
energy, food, water, etc.;

c. Environment: which includes protection, waste and emissions control against climate
change;

d. Governance: in terms of ensuring urban utility and service availability;
e. Economy: in terms of sustainable growth and city competitiveness (attracting habitants,
visitors and businesses).

Other approaches [1, 2] discuss about urban mobility in terms of transportation, which can be
concerned part of the above Living dimension; resilience in terms of resistance against natural
disasters, pandemics, terrorist attacks, accidents, etc. [3], which can be addressed by the above
environment and governance SSC dimensions (Figure 4); innovation in terms of urban innovation
[4], which is mainly disruptive, although the smart sustainable city becomes steadily a social
innovation [5].

On the other hand, ITU Focus Group on SSC (FG‐SSC) has delivered its document regarding Key
Performance Indicators' (KPIs) definitions, which aligns to the United Nations Habitat dimensions
(Table 1).

Table 1 – ITU SSC key performance indicators (KPIs)

SSC dimension

ICT
Environmental sustainability
Productivity
Quality of life

Equity and social inclusion
Physical infrastructure

The above characteristics illustrate the complex SSC nexus (shown Figure 1), where the five
dimensions match the SSC KPIs (Table 2), matching was performed with the comparison of SSC KPIs

with each of these dimensions and an important finding showing that complete matching is
performed between ICT, Quality‐of‐Life and Physical infrastructure SSC KPIs with SSC dimensions,
while the Living and Government SSC dimension matches to all SSC KPIs.
