IN THE SPOTLIGHT
How the ITU Helps Build People-Centred Smart Cities and Communities

Standardization with Global Reach: ITU-T Study Group 20
ITU-T Study Group 20 (SG20): Internet of Things, digital twins and smart sustainable cities and communities develops international standards (ITU-T Recommendations) providing commonly agreed guidance for implementing the Internet of Things (IoT) and its applications, digital twins, as well as sustainable cities and communities and related digital services. Its work spans IoT technologies, city services, policy frameworks, impact assessments, and open-source solutions, promoting secure, accessible, and sustainable systems. SG20 accelerates digital transformation, fostering global innovation for both urban and rural areas.
The ITU Study Group 20 meeting will take place on 15-25 September 2025 in Geneva, Switzerland
Digital Transformation Dialogues (DTD)
The Digital Transformation Dialogues (DTD) offer a dynamic platform to facilitate a deeper understanding of emerging technologies to reshape traditional processes, improve operational efficiency and unlock new possibilities for innovation and standardization. Engage in illuminating discussions that propel digital transformation forward by joining our webinars, fireside chats and ask the expert sessions.


United for Smart Sustainable Cities
The United for Smart Sustainable Cities (U4SSC) is a global UN initiative that supports cities and communities in accelerating digital transformation and achieving the Sustainable Development Goals. The U4SSC accomplishes this through its Thematic Groups, developing action plans and guidelines, and the Key Performance Indicator project, which evaluates ICTs’ role and provides tools for self-assessment to promote smartness and sustainability in cities.
KPIs for Smart Sustainable Cities
The U4SSC KPIs are a vital tool for cities wishing to achieve the UN Sustainable Development Goals. They support cities and communities worldwide in evaluating their level of smartness and sustainability. Over 200 cities worldwide are already implementing these KPIs.
