15-minute city
Definition
An urban planning concept proposed in 2016 by Franco-Colombian researcher Carlos Moreno, under which residents can access six essential urban functions — living, working, supplying, caring, learning and enjoying — within roughly 15 minutes by walking or cycling. It rests on four pillars: density, proximity, diversity and digitalisation.

Overview
What it means
The model applies "chrono-urbanism" — organising the city around time rather than speed. It calls for mixed-use neighbourhoods where daily needs are close by, reducing dependence on cars and returning street space to people. Paris adopted the approach under Mayor Anne Hidalgo from 2020, and variants exist in many cities (for example 20-minute neighbourhoods in Melbourne).
How it is used
City governments and planners use the concept to frame strategies for walkability, cycling infrastructure, local services and low-carbon mobility. It gained momentum during the COVID-19 pandemic as cities sought proximity-based resilience, and it is referenced in urban sustainability and climate discussions worldwide.
Why it matters
Transport is a major urban emissions source; proximity planning cuts car trips, air pollution and commuting time while supporting local economies.
Since 2023 the concept has also been the target of widely debunked conspiracy theories falsely claiming it involves confining residents to zones — misinformation that fact-checkers and researchers attribute to confusion with unrelated traffic-filter schemes, notably in Oxford.
Definitions and controversy
The planning concept itself is stable, but it has become politically contested through misinformation; implementation debates (gentrification risk, feasibility in low-density areas) are genuine planning discussions distinct from the conspiracy claims.
