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.
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 250 cities worldwide are already implementing these KPIs.
The Global Initiative on AI, Digital Twins and Virtual Worlds – Discovering the Citiverse, launched by ITU, Digital Dubai, and UNICC, is a global platform advancing the AI-enabled citiverse where AI, spatial intelligence and digital twins converge to deliver real-world impact.
Supported by more than 70 partners worldwide, the Initiative brings together governments, industry and the UN system to promote safe, open and interoperable ecosystems, enabling public service transformation, economic growth and digital trust.
The 2nd Citiverse Assembly, co-organized by ITU, European Commission and OASC, and supported by StandICT.eu, took place on 12 May 2026 at ITU Headquarters in Geneva. More information will be made available here.
ITU together with other organizations, cities and other UN agencies are organizing a series of meetings and events on digital transformation for cities and communities. Don’t miss out on these key events.
