A “smart and sustainable city” is one that uses technology and innovation as tools to improve the quality of life of its inhabitants, efficiently manage its resources and respond adaptively to urban challenges, all in harmony with the environment. and with a long-term vision in mind. The convergence of technological intelligence with sustainability is essential to create urban environments that are not only efficient and connected, but also resilient, inclusive and respectful of the natural environment.

The “smart” component refers to the use of advanced technologies, such as the Internet of Things (IoT), geographic information systems (GIS), big data analysis and connectivity platforms, to collect, analyze and use information in real time. These technologies allow the city to quickly adapt to changing needs, foresee problems and make data-driven decisions. For example, through real-time sensors and analytics, a smart city can manage traffic flow, optimize energy distribution, and improve emergency response.

The “sustainable” component emphasizes the need for cities to adopt practices and policies that reduce their environmental impact, promote social equity, and foster a resilient economy. This involves, among other things, promoting energy efficiency, using renewable energy sources, managing natural resources responsibly, promoting green mobility and ensuring that all citizens have access to basic services and opportunities. A sustainable city seeks a balance between current and future needs, ensuring that future generations have the same, if not better, opportunities and quality of life.

The Thematic Group on Smart and Sustainable Cities, in meetings held on March 5-6, 2014 in Geneva, agreed on the following definition:

“A smart and sustainable city (SSC) is an innovative city that uses information and communication technologies (ICT) and other means to improve the quality of life, the efficiency of urban operation and services, and competitiveness, guaranteeing the at the same time satisfying the needs of present and future generations with respect to economic, social and environmental aspects.”
