930 ITU‐T's Technical Reports and Specifications 4.3 Types of standardization work Given the challenges identified above, there are a number of types of SSC standards‐related work that could potentially be undertaken by ITU and that could support cities in becoming smarter and more sustainable: developing standards related to ensuring interoperability and coherence between different city systems and to enable cities to assess progress and benefits from smart city initiatives studying SSC‐related issues (such as city security, city resilience, privacy and data protection, etc.) in partnership with the related study groups and focus groups within ITU to: (a) identify if there are any gaps in the existing standards relating to those issues so that these gaps can then be tackled by the related standards groups; (b) develop guidelines for city leadership on how to bring together the appropriate portfolio of the related standards in that area that will enable the standards groups to tackle that issue. developing guides that match the suitability of the various ICT techniques to the plenty of services a smart sustainable city needs, highlighting best practices available. developing guidelines of the key technologies and trends which can have an impact in implementing the smart sustainable city strategies, in partnership with the related study groups and focus groups within ITU, aimed at SSC practitioners, to help them understand the relevance of these technologies and trends, and the standards underpinning them. liaising with related ITU study groups and focus groups and with other international standards bodies, potentially in partnership with ISO/TMB SAG on Smart Cities and IEC/SMB SEG 1 on Smart Cities, to: (a) ensure that standards are being developed in technologies related to smart and sustainable cities, and within individual city systems, and take into account any specificity relating to smart and sustainable cities; (b) identify developing good practices that might be developed into ITU standards; (c) support co‐ordination of international work on SSC standards to avoid overlaps and ensure greater consistency between the standards that are developed. A document of ITU‐T FG‐SSC provides a list of standards that have already been developed in the area of smart and sustainable cities, a description of the work that other standards bodies are doing in this area and a summary of key networks and initiatives that are developing good practice and guidelines for cities [ITU‐T TR standard].
