What is the 15-Minute City? An Explainer

Having everything we need a stone’s throw from our front door would surely make life much easier. But the 15-minute city isn’t just about proximity.

Imagine an elderly person unsteady on their feet. If that’s you, maybe you recognise this scenario. We’ve all seen someone fragile moving along the street purposefully. Maybe they’re on the way to do buy groceries.

That person would probably appreciate having the shop closer to home, reducing the time and energy needed to make that journey – especially when weighed down with heavy bags. A bench or two along the way, offering a chance to rest, probably wouldn’t go amiss either – especially one shaded by a tree in the summer months.

This is essentially what the 15-minute city proposes: having all the essentials we need for everyday living within a reasonable proximity. Not just infrastructure for convenience, but to improve quality of life.

But the 15-minute city concept seems to be wildly misunderstood, and often misrepresented. So let’s take a look in more depth at what it actually is, what is isn’t, and what it looks like when the principles are applied in reality.

Introducing the 15-minute City

In a change from unplanned, historic cities which grew and evolved organically, twentieth century urban planning was keen on zoning: a residential estate here, a retail park there. The various functions of our lives were separated. It was (is!) a model built around the motor car. But reliance on independent travel has trapped citizens in fragmented cities that require us to travel longer distances. The average European living in cities has a longer work commute than suburban and rural populations, for example.

And not just from home, but from place to place.

This standard penalises those who cannot afford their own car and is more of an inconvenience for anyone dependent on public transport – if there is any.

The 15-minute city concept flips that around, proposing decentralised cities where neighbourhoods offer more of what we need closer together; close enough that we can get between them by walking, rolling, skating, or cycling within a reasonable amount of time.

Grocery stores are only the start. Services and social infrastructure that a 15-minute city offers could include: schools and kindergartens; parks and green spaces; doctor surgeries and pharmacies; community centres and places of worship; lakes, ponds, and other blue infrastructure; laundrettes; bike hire and repair shops; job opportunities; legal services; and leisure activities – from swimming pools and sports centres, to cinemas and youth clubs.

Design of the 15-minute City

Some urbanists prescribe to specific constraints of 15-minute city design, such as putting parks and schools within a 5-minute walk of home, and services like healthcare accessible within 15. Carlos Moreno, the academic who first coined the idea a decade ago, does not seem to share this thinking.

In 2026, he wrote that the “15-minute city is not a checklist or a list of constraints. It is a framework for reimagining cities and territories through the mix of six essential urban functions: where we live, work, learn, access healthcare, enjoy public spaces, and access commerce and services in proximity”.

Carlos cites examples around the world of 20- and 30-minute versions, especially where this suits less dense neighbourhoods. Similar variations were found in a survey of five European 15-minute districts. Rather than a concrete timeframe, what’s important – Carlos argues – is making cities “pleasant, agile, healthy, and flexible”.

Characteristics of the 15-minute City

Everyone familiar with 15-minute cities knows about the top tier criteria of proximity, but Carlos has spoken openly about three other “key building blocks”:

• Participation – give citizens a voice in the creation of their 15-minute neighbourhood
• Solidarity – spaces that allow people to come together, mix, and build relationships
• Ecology – to sate our innate craving for connection with nature, greenery, and water

These principles should be applied and adapted to suit each location.

A study by researchers at the Technical University of Munich, Germany, looked into 16 real life examples, including Paris (France), Dublin (Ireland), Hailsham (UK), Utrecht (Netherlands), Melbourne (Australia), Ottawa (Canada), Portland (USA), and Singapore. Although these international locations span multiple geographies, and although each interpreted the 15-minute city in their own way, the research identified a roster of consistencies, some of which correlate with Carlos’ four key principles:

• Mixed land use and urban density create conditions for people to be closer to what they need (proximity)
• Increased accessibility improves inclusion and equity among diverse populations (solidarity)
• Active mobility is encouraged by well thought out and safer cycling and pedestrian infrastructure (participation)
• Human-centric streets and public spaces are more vibrant and populated, with a better sense of community (solidarity)

Add to this reduced reliance on private mobility means; destinations further afield are within reach via well-connected public transport.

What a 15-minute City is Not

All sounds great, doesn’t it? Hard to believe anyone could not see the good in the 15-minute city, but it has proven quite controversial. So, what’s all the hoo-hah about?

A prominent example occurred in Oxford, UK, in 2022. People took to the streets to protest against a 15-minute city proposal, which they believed to be a form of controlling civil liberties, like freedom of movement in an attempt led by the global elite to curb climate change. It seems to have stemmed from negligent reporting (since debunked) and stirred up to a frenzy by armchair commentators, leading even to death threats for those held responsible.

More generally, conservative politicians have weaponised disinformation to swing popularity, and in the USA, prominent right-wing broadcasters have perpetuated the myths.

Their claims are patently not true. Carlos Moreno is on record as saying that “the goal is not to oblige people to stay within the 15-minute district. We don’t want to recreate a village. We want to create better urban organisation”.

And yet, for UK neighbourhoods, these conspiracies have gained a footholds and caused difficulties for councils or community groups attempting to implement adjacent initiatives, like  Low Traffic Neighbourhoods (LTNs), which are designed to improve air quality, reduce excessive noise, etc.

Traffic Control is Always Contentious

LTNs are effectively streets or neighbourhoods that are accessible only via soft and micro-mobility, similar to Barcelona’s superblocks. Some formerly had car access but have been closed-off by barriers or – more pleasantly – planters, adding a touch of ecology. In London, UK, LTNs have been found to reduce injuries and deaths by at least 35%.

Objectors claim that LTNs push traffic – and therefore congestion – onto nearby roads, which is occasionally true. More extreme arguments – like those in Oxford – say that this is a conspiracy to keep people contained. There’s no evidence to support this.

But anyway, 15-minute cities aren’t LTNs. Nor are they low emission zones, where vehicles running on fossil fuels and other polluting activities like burning solid waste are limited or prohibited. LEZs have also drawn fire in London for drivers being charged each time they enter, as a prevention.

Theoretically, 15-minute cities are not car-free at all. When he came up with the idea, it’s true that Carlos saw them as centres of low emissions, but because people would be able to – and so choose – to get around by foot and bike. The decline in car use would presumably take care of itself. (Although not a story about 15-minute cities, we have seen this behaviour become mainstream in Rimini, Italy.)

Benefits of the 15-minute City

Which brings us to the meat of the matter – what cities actually stand to gain.

In a 2021 paper, Carlos himself outlined the main advantages. A rise in active transport, he argues, can lower a city’s transport emissions. Not before time. Globally, in 2023, 15% of all emissions originated from transport and at the start of this decade, 60.7% of Europe’s CO₂ emissions emanating from road transport were from run-of-the-mill household cars.

By bringing everything people need within – let’s say, for sake of argument – a 15 minute walk, citizens’ lifestyles improve dramatically. We’re not only talking about shops, schools, and banks, but also green spaces: trees that purify the air, soak up stormwater, reduce heat, attract wildlife, and provide a pleasant place to play.

That all contributes to better health. As does proximity to healthcare facilities, and the fact that people are moving more; in an ingenious move, Oklahoma City in the USA put 15-minute cities at the centre of their obesity strategy.

Proximity has a secondary benefit too – affordability. “Auto debt” – taking out loans to pay for a car many low-income earners can ill afford but cannot do without – is rife, especially in the USA’s sprawling cities. Short range distances of the 15-minute city removes this burden.

Making Places Where People Want to Be

There’s more. Mixed land use opens empty rooms in local buildings up to office space. In addition to being a springboard for job opportunities, this potentially reduces commuter journeys, giving people more free time to enjoy as they please – spending time on hobbies, relaxing, or with people they love.

Carlos actually wrote, for New Polis, that the 15-minute city is about reclaiming time, as improved proximity removes the need to sit in traffic jams for hours each year.

Creating quality public spaces that people actually want to be in allows chance encounters to occur, resulting in people feeling connected and cared for, reducing loneliness. This might be especially pertinent to the elderly. Everyone gains from the reduction in crime that comes from improved social cohesion, and the sense of ownership they get from helping shape their neighbourhood in the first place.

Then of course there are the economic benefits; increased footfall encourages people to spend locally, and active mobility restores life to high streets and city centres.

15-minute Cities in Practice

Carlos’ home city of Paris, France, is always, reasonably, trotted out as a solid example of how a 15-minute city can leap from idealistic concept to effective urban environment.

Former mayor Anne Hidalgo took a risk on a programme that she called La Ville Du Quart d’Heure (the quarter-hour city). Leaving office in 2026 after 12 years, she had overseen the planting of 155,000 trees, the creation of 63,000 hectares of urban green space, an increase in affordable social housing, and the transformation of car roads and parking spaces into school streets and cycle lanes. This ambitious plan was not just about proximity, but about how Parisians live day-to-day.

C40 mapped a handful of other examples that show how different 15-minute cities can be in practice. It’s striking how many of them focus heavily on creating routes for active mobility, enabling citizens to access existing provision easier.

In Denmark, Copenhagen’s Municipal Plan 2024 aims for “every resident to live within 300 meters of a high-quality green space or water access,” to put everyone daily contact with ecology.

Busan, the second biggest city in the Republic of Korea, openly recruited people to a citizens’ group to guide the city’s vision after mayor Park Hyung-joon committed to integrating smart tech into residents’ lives from the start of his tenue. He also created a dedicated 50-person strong department to deliver on Busan’s 15-minute city vision.

Portland, Oregan, USA, is a little more down-the-line. Its Portland Plan outlines a vision for the “complete neighborhood”, consisting of housing, commerce, education, entertainment, recreation, and transportation. It prioritises “underserved neighbourhoods – typically lower-income neighbourhoods and those with high populations of colour” to advance equity among its citizens.

Further Challenges

Clearly, there are many successes, showing how, in just a decade, the idea of 15-minute cities have taken our imaginations – as well as our decisions, policies, and planning departments – firmly in its grip.

At least one issue does remain with the concept, which cities need to be on the lookout for: proximity does not necessarily equate to accessibility.

As Maria Paipai, an urban and transport planner based in Limassol, Cyprus, posted on LinkedIn: “In many cities, we frequently encounter the phenomenon of ‘theoretical proximity’” – when a destination looks close on paper (as the crow flies), but the snaking routes that lead to it in reality take much longer. Barriers may be put in place, for example, by wide roads, railway lines, rivers, and industrial areas.

Even if there’s a clear through route, the urban fabric – even down to the material of the surface we have to tread – can be a limiting factor.

“Accessibility is about ability, safety, and dignity,” Maria writes. A 15-minute city only works if everyone has the same level of access, including people with mobility challenges and parents with young children in a pram. The elderly person we met right at the start might struggle with raised curbs, cobbled streets, and slippery surfaces as much as they would long distances.

In the vision that Carlos maintains, mismanagement would be avoided: 15-minute cities are a holistic endeavour, where all factors are considered and shaped by the diverse user groups who use a place.

The Changing Face of 15-minute Cities

Still, we might not get it 100% right first try. And maybe that’s okay.

Writing for the Congress of New Urbanism, Andres Duany and Robert Steuteville suggest that “imperfections” in a 15-minute neighbourhood “can serve a purpose”. They pose that a “less valuable area could be an opportunity for lower rents and gritty attractions like a nightclub that may be inappropriate elsewhere,” for example.

Carlos himself often writes of how spaces can be multifunctional, serving one purpose during the day and another at night.

These are the types of nuanced opportunities that the 15-minute city offers, although which are easy to miss if we only think of the concept in terms of proximity. In truth, it is a concept that is as diverse and adaptable as the cities that care to give it a go. Although some people may fear that at first, given time to bloom, they do appear to be universally successful.
