10、ies Summary Supplement 45 to the ITU-T Y-series Recommendations provides an overview of roles of information and communication technologies (ICTs) in smart sustainable cities (SSCs) primarily based on ITU-T Recommendations. An SSC aims to improve quality of life (QoL), efficiency of urban operation
11、and services, as well as competitiveness, ensuring that the needs of present and future generations with respect to economic, social, environmental and cultural aspects of cities and communities are met. SSCs in general, share the goal of achieving an economically sustainable urban environment witho
12、ut compromising the QoL of their citizenry. A smart city and community strives to create a sustainable living environment for citizens using the Internet of things (IoT), enabled by ICTs. An IoT-based infrastructure, enabled using ICTs, can continue to play a pivotal role in SSCs by functioning as a
13、 platform for the aggregation of information and data that can help government officials and citizens understand how the city is functioning in terms of resource consumption and services.

The ITU Telecommunicatio
16、n Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis. The World Telecommunication Standardization Assembly (WT
17、SA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics. The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1. In some areas of information technology which fall
18、within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with ISO and IEC.

However, the publication may contain certain mandatory provisions (to ensure, e.g., interoperability or applicability) and compliance with the publication is achieved when all of these mandatory provisions are met.

29、 1 Scope This Supplement provides an overview of smart sustainable cities (SSCs) and the role of information and communication technologies (ICTs) based on ITU-T Recommendations relevant to SSCs. This Supplement provides information on: goal and city dimensions of SSCs; usage of ICTs in the SSC cont
30、ext; sustainability impacts of ICTs on SSCs; evaluation of achievements of SSCs. This Supplement does not intend to define technical requirements or to mandate any particular technologies that could be used when developing smart cities. It does not intend to compare tools, applications or platforms
31、that could be used in smart cities. 2 References ITU-T L.1302 Recommendation ITU-T L.1302 (2015), Assessment of energy efficiency on infrastructure in data centres and telecom centres.

A variety of factors such as size, location, population growth projections, economy, brand, values, workforce and age profile are examples of compon
41、ents that impact a city Y series Supplement 45 (09/2017) 3 and its goals. A citys vision and strategy could take into account a variety of characteristics such as these, seeking to address relevant challenges and identify opportunities. Adopting a goal-oriented strategy based on a citys unique chara
42、cteristics can provide new ways to meet citizen needs and new business opportunities for local industry. The goal of an SSC is, through efficient management of resources and infrastructure, to make the city run in a smart and sustainable way, so as to improve the quality of life (QoL) of its citizen
43、ry across multiple, interrelated dimensions, including (but not limited to) the provision of and access to water, energy, transportation, education, environment, waste management, housing and job opportunities. It requires efficient use of ICTs, while ICTs act as a platform to help meet these challe

45、ions. Environmental dimension: The ability to protect the existing as well as the future quality and reproducibility of natural resources. The city is expected to be sustainable in its functioning for future generations, see clause 6.2.1. Economic dimension: The ability to generate income and employ
46、ment for the livelihood of the citizens. The city is expected to be able to thrive, e.g., jobs, growth and finance, see clause 6.2.2. Social dimension: The ability to ensure that the welfare (safety, health, education, etc.) of citizens can be equitably delivered despite differences in class, race o
47、r gender. The city is expected to serve its inhabitants and visitors, see clause 6.2.3. Governance dimension: The ability to maintain social conditions of stability, democracy, participation and justice. The city is expected to be robust in its ability to administer policies and pull together the di
48、fferent categories, see clause 6.2.4. 6.2.1 Environmental dimension According to b-UN-Habitat, on a global scale, cities present the greatest environmental policy challenge, representing 75% of energy consumption and 80% of carbon dioxide (CO2) emissions. Therefore, environmental sustainability is o
49、ne of the most critical components in the functioning of any city. The following categories of the environment dimension should be considered by cities: city environmental management: environmental strategy, integrated environmental management, municipal administration on environment, effective environmental conservation; energy and climate change: CO2 emissions (CO2 from energy production, emissions per capita, etc.), energy (energy performance,
