12、REWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and communication technologies (ICTs). The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studyi
13、ng 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 (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups
14、 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 within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with ISO
15、 and IEC. NOTE In this publication, the expression “Administration“ is used for conciseness to indicate both a telecommunication administration and a recognized operating agency.

22、cio-economic growth and environmental crises since the latter half of the 20th century and the beginning of the 21st century. In 2014, there were 28 mega cities, home to 453 million people. With 54% of the worlds population living in urban areas, cities are confronted with contemporary problems, inc
23、luding rapid urbanization, rising pollution levels and an ever increasing rural to urban migration, all of which have exerted pressure on ageing city infrastructure. Projections indicate that the percentage of the global population living in cities is expected to rise to 66% by 2050 b-WHD. Globally,
24、 cities also account for 75-80% of a countrys GDP and are considered the main engines of global economic growth b-UNEP. On the flip side, cities also produce 50% of the global waste b-CB along with 60% of the global greenhouse gas (GHG) emissions b-CCCM. As a result, there is increasing pressure on
25、existing natural resources such as water, land and fossil fuels b-Naphde. Additionally, there are growing concerns regarding existing transportation infrastructure, provision of adequate healthcare, access to education and overall safety for the growing population of urban residents b-ERSC.

27、 its future development trajectory. Accordingly, this high level policy document helps identify practical steps based on which urban decision makers can envisage and build a smart sustainable city (SSC). 2 References None. 3 Definitions 3.1 Terms defined elsewhere None. 3.2 Terms defined in this Rec

30、to issues such as increasing population, resource overuse and dependence in cities. Understanding this dilemma, ITUs Focus Group on Smart Sustainable Cities (FG-SSC) set the path for cities to become smart and sustainable. Smart sustainable cities (SSC) is a concept developed by the FG-SSC which int
31、ends to leverage the potential of information and communication technology (ICT) in urban governance systems to create cities which are not only economically and socially advanced but are also designed to achieve environmental sustainability. 2 Y series Supplement 32 (01/2016) This Supplement is int
32、ended for city decision makers and strategists, whose decisions have a significant impact on the way their city functions and its future development trajectory. Accordingly, this high level policy document helps identify practical steps based on which urban decision makers can envisage and build a s
33、mart sustainable city. 7 Starting your SSC journey For cities wishing to go the SSC way, each city has to start from a different baseline for their transition to becoming a smart sustainable city. However, it is important to understand that SSC means embracing a journey and cannot be considered the
34、final destination. Through its research work on SSC, ITU intends to assist city decision makers (including municipal and government representatives) by re-defining the way in which the citys infrastructure is built, services are offered, citizens are engaged and systems linked, with the aim of trans
35、forming cities into more sustainable, smart, resilient and robust living environments. Realizing that the establishment of SSC is a long term process and cannot be achieved overnight, it is essential that a series of generic steps are defined that would not only allow for comparability but would als
36、o promote sustainable development along with each city being able to quantify improvements over time. In keeping with this way of thinking, the ITU has developed some basic steps for SSC transformation. Each of the steps described in this document are required when making the transition to a smart s
37、ustainable city. These steps can help formulate an action strategy oriented to: (i) consensus building among varied stakeholders, (ii) governance mechanisms, (iii) citizen engagement, (iv) ICT infrastructure, (iv) monitoring mechanisms and (v) learning among SSC stakeholders. Figure 1 gives an overv
38、iew of the steps to becoming a smart sustainable city (SSC). Figure 1 SSC 6-step transition cycle (Adapted from b-ICLEI) Step 1 Set the vision for your SSC venture Local government should increasingly take on a more central role in such development initiatives. They should assist in identifying a sp
39、ecific SSC vision and in assessing the citys existing situation Y series Supplement 32 (01/2016) 3 in order to establish the relevance and feasibility of becoming a smart sustainable city. This step includes the following aspects: a) Identifying an SSC vision that is in line with the citys identity,
40、 political priorities and long-term development strategy; b) Gathering relevant data on the status of ICT infrastructure and its usage at the city-level, including the status of the city in regards to the widely used ITU-T Recommendations and Technical Reports; c) Identifying the SSC stakeholders; d
41、) Identifying the existing governance and organisational mechanisms that would allow an efficient and effective management of SSC solutions; e) Identifying mechanisms for multi-stakeholder involvement, citizen engagement, communication and information sharing throughout the SSC process. This step ca
42、n be facilitated through a basic SSC strengths, weaknesses, opportunities and threats (SWOT) analysis for each city. This will assist in framing a city specific strategy and goals. Step 2 Identify your SSC targets Local government should work in close collaboration with the various SSC stakeholders
43、to design the overall master plan for the SSCs implementation. This should include broad agreement on objectives, priorities, initiatives and actions needed in the short, medium and long term. Consideration should be accorded to setting measurable SSC targets and timeframes for their achievement. Th
44、is step involves, among others, the identification of SSC targets in regards to: a) Developing SSC infrastructure and an integrated platform for example using Internet of things (IoT); b) Identifying and developing SSC services; c) Defining SSC key performance indicators (KPIs); d) Educating the sta
45、keholders on the advantages of SSC. Step 3 Achieve political commitment Engagement with political leadership is imperative. Local governments should obtain the necessary political approval and backing to ensure that the SSC strategic programme is pursued. This includes the adoption of the SSC progra
46、mme/targets through consensus. This will provide the basis for an agreed document that has widespread support and will serve as a reference for the strategic planning by the local authority. Step 4 Build your SSC Using the political backing gained in Step 3 and support from other SSC stakeholders, l
47、ocal governments should lead the way to actually initiating the establishment of their smart sustainable city. For this step, the existing traditional infrastructure may be significantly improved on by integrating the required ICT applications for the upgrade to SSC. The stakeholders may also choose
48、 to build a new infrastructure from scratch. For either of the aforementioned scenarios, the following features are pertinent: a) Making of a feasible master plan for your SSC journey; b) Conforming to appropriate construction models (e.g., public-private partnerships in various SSC programmes); c)
49、Ensuring long term services via good operation and maintenance after the infrastructure is in place. 4 Y series Supplement 32 (01/2016) Step 5 Measure your city progress The fifth step consists of monitoring and evaluating a work programme required to achieve the targets. This stage involves close coordination and collaboration among SSC stakeholders, as well as an assessment on the basis of relevant key performance indicators (KPIs). The ITU has developed a useful set of KPI
