The "United States of the World" and the “Fondazione Mediterraneo” organised and participated in various events around the world to celebrate "World Cities Day", established by the UN General Assembly in 2013 with the aim of promoting international interest and cooperation between countries to address the challenges of urbanisation and contribute to sustainable urban development.
‘Better City, Better Life’ is the slogan accompanying World Cities Day 2025.
‘Cities,’ said Secretary-General Prof. Michele Capasso, "are destined to become increasingly large and complex. According to the report prepared by the “United States of the World”, urban areas currently occupy just over 2% of the Earth's surface and are home to more than half of the world's population (a figure that is expected to rise to over 60% by 2050), causing 60% of the planet's polluting emissions and consuming 78% of the energy produced globally. Cities are at the heart of the future, and we must all accompany this transformation with vision, responsibility, passion and a sense of the common good. 
"We need to take action, says Prof. Massimo Pica Ciamarra, president of the CSI of the 'United States of the World', to make cities inclusive and safe through increasingly innovative solutions with the aim of regenerating degraded urban areas from a building, energy and social perspective. The use of data, technology and artificial intelligence can tangibly improve urban life, making cities more efficient, sustainable and resilient in the face of the challenges of our time." 
On this occasion, the first proposal for the large representative headquarters of the "United States of the World" was presented.
