The 15-minute city model promotes sustainable urban planning based on the concept of proximity, reducing car dependency and encouraging active mobility, such as cycling and walking. The goal is to ensure that every citizen can access essential services – housing, work, education, healthcare, commerce, and leisure – within a 15-minute radius, enhancing quality of life while minimizing environmental impact. 

This concept, developed by urban planner Carlos Moreno, draws inspiration from the principles of polycentric cities and community-oriented planning, fostering the creation of self-sufficient and vibrant neighborhoods. Today, the challenge is not only to design more accessible urban spaces but also to bring essential functions and services closer together, reducing the need for long commutes. This approach has been adopted in cities such as Paris, where Mayor Anne Hidalgo integrated it into the urban transformation plan, as well as in other metropolitan areas seeking a sustainable transition in urban mobility.
