• Leading the development of ITU standards for IoT and Metaverse in smart cities and communities

Smart and Sustainable Cities

The development of international standards will help provide SMEs, policy makers and regulators with common references thus helping overcome market barriers such as technology fragmentation, thus promoting market growth.

A clear trend is being formed of moving from vertical energy management that distributes energy in a wired, centralized manner towards more open and distributed architectures adopted close to the edge of the population networks, which among other technologies also utilize the wireless power potential. In this new paradigm, energy will be distributed, shared and managed locally, thus closing the distance between citizens and the available energy sources.

ITU-T Q5/20 studies emerging technologies and active work items include topics of high-relevance to European market, such as Digital Product Passports. The development of international standards will help provide European SMEs, policy makers and regulators with common references thus helping overcome market barriers such as technology fragmentation, thus promoting market growth.

The work items of Question 5 of ITU-T Study Group 20 collectively support significant societal impact by advancing the integration of intelligent, sustainable, and transparent digital systems. The development of standards such as the Digital Product Passport for ICT goods (Y.DPP-ICT and YSTR.OS-DPP-ICT) promotes circular economy practices, enabling traceability, sustainability, and responsible consumption. Initiatives like Y.CIP enhance public safety through metaverse-based emergency response systems for chemical industrial parks, leveraging immersive technologies for disaster preparedness and risk management. Frameworks for distributed intelligent computing (YSTR.DIC) and embodied artificial intelligence (YSTR.EAI) contribute to the evolution of smart sustainable cities by enabling efficient resource utilization and human-centric automation. Meanwhile, the Hybrid AI-based Oral Assessment Platform (YSTR.AIOAP) reflects the application of ethical AI in education and skills evaluation. Together, these efforts foster safer, smarter, and more sustainable digital societies aligned with the UN Sustainable Development Goals.
