KPIs for Smart Sustainable Cities​

The U4SSC Key Performance Indicators (KPIs) are a recognized UN standard for cities focused on achieving the UN Sustainable Development Goals (SDGs). These KPIs provide a comprehensive framework that helps cities and communities worldwide assess and improve their levels of smartness and sustainability, with an emphasis on creating people-centred smart cities that prioritize the well-being of citizens.

Adopted by over 200 cities globally, the U4SSC KPIs are empowering cities and communities to become more sustainable, innovative, and responsive to the needs of their inhabitants.
