The 15-Minute City is an innovative urban planning concept championed by Professor Carlos Moreno from the Sorbonne University in Paris. This model advocates for city designs that allow residents to fulfill all essential daily needs within a 15-minute walk or bicycle ride from their homes. These necessities cover six core urban functions: housing, employment, food, healthcare, education, and culture and leisure. Unlike a nostalgic return to village life, the 15-Minute City embraces urban advantages such as vibrancy, creativity, diversity, innovation, and active citizenship, while also aiming to reduce reliance on private vehicles and long commutes.
The roots of this concept lie in "chrono-urbanism," which posits that the quality of urban life diminishes with increased time spent on transportation, especially by car. Moreno's vision of a "living city" centered around proximity led to the emergence of the 15-Minute City, gaining traction when Anne Hidalgo, the Mayor of Paris, integrated it into her 2020 re-election campaign and urban transformation plans.
The 15-Minute City is guided by four key principles:
- Proximity: Essential services should be close to residences to minimize long journeys.
- Diversity: Neighborhoods should feature a mix of residential, commercial, educational, cultural, and recreational spaces, instead of being zoned for single purposes.
- Density: A sufficient concentration of people and services is necessary to sustain local economies and public services.
- Digitalisation: Technology complements physical proximity by enabling remote work, digital public services, and data-driven urban planning.
Cities around the world have started to adopt and adapt the 15-Minute City concept.
- In Paris, significant changes include pedestrianized streets, expanded cycling infrastructure, and transformed car parks into green spaces.
- Melbourne has initiated the "20-Minute Neighbourhood" program, which aligns with the accessibility goals of the 15-Minute City.
- Barcelona is implementing the "superblocks" initiative to prioritize pedestrians and cyclists.
- Portland aims for 90% of residents to meet their daily needs within a 20-minute walk through its "complete neighbourhoods" policy.
- Edinburgh incorporates 20-minute neighbourhood principles into its long-term development plans.
- Milan has integrated the concept into its post-pandemic urban recovery plans.
- Buenos Aires is aligning its neighborhood planning with 15-Minute City principles.
Researchers have developed quantitative methods to measure 15-minute accessibility at the neighborhood level. This typically involves mapping the walking and cycling catchment areas and assessing the proportion of residents who can access essential amenities within the designated time. Studies have identified disparities in accessibility, particularly in peripheral and lower-income neighborhoods.
Despite its growing acceptance, the 15-Minute City concept faces criticism. Concerns include housing affordability, as proximity to essential services can lead to increased property values and potential displacement of residents. Critics also question the model's feasibility in low-density suburban areas and cities in the Global South with informal economies. Some political movements have circulated conspiracy theories suggesting the concept would restrict freedom of movement, which has been contested by planners and scholars.
The 15-Minute City framework provides a human-centric approach for urban development. For smart city practitioners, it offers a lens to utilize digital tools that enhance local accessibility and improve quality of life. This concept aligns with the European Green Deal, the New European Bauhaus initiative focusing on sustainability and inclusion, and the UN Sustainable Development Goals for creating greener and more equitable cities.
