The Rise of the 15-Minute City

AFor most of the twentieth century, urban planners across Europe, North America, and Australia designed cities around the private car. Wide arterial roads, multi-lane highways, and vast areas of surface parking transformed once-walkable neighbourhoods into landscapes dominated by traffic. In many cities, historic streets were demolished to make way for new roads, and post-war suburbs were laid out with the assumption that every household would own at least one vehicle. The consequences were far-reaching: longer commutes, increased air pollution, the gradual decline of independent local shops, and the loss of public spaces where children could play and neighbours could meet. By the 1990s, a growing number of urban researchers were beginning to question whether this model could be sustained.

BThe concept of the so-called 15-minute city emerged as one response to these concerns. Popularised by Carlos Moreno, a French-Colombian academic based at the Sorbonne in Paris, the idea proposes that residents of any neighbourhood should be able to meet most of their daily needs within a fifteen-minute walk or bicycle ride from their home. These needs include access to schools, healthcare, food shops, workplaces, parks, and cultural facilities. Moreno did not invent the idea entirely on his own; earlier planners, including Jane Jacobs in the 1960s, had argued for similar approaches. However, Moreno's contribution was to package these older ideas into a clear, measurable framework that could be presented to mayors and policymakers as a practical goal rather than a vague ideal.

CParis has become one of the most prominent examples of this approach in practice. Under Mayor Anne Hidalgo, the city has reduced the number of car lanes on major roads, expanded its network of protected cycle paths, and pedestrianised long sections of the Seine riverbank that were formerly used by motor vehicles. Schools have been redesigned to serve as community hubs outside teaching hours, opening their courtyards to local residents in the evenings and at weekends. Other cities, including Melbourne, Portland, Milan, and Barcelona, have followed with their own versions of the concept, sometimes under different names. In Barcelona, the superblock model groups several city blocks together, restricting through-traffic in the interior and reclaiming the streets for pedestrians, cyclists, and outdoor seating.

DSupporters of the model offer several arguments in its favour. Reducing dependence on cars, they say, lowers carbon emissions, improves air quality, and encourages physical activity. Local economies often benefit too, as foot traffic in pedestrianised areas tends to increase, and small businesses report higher sales once parked cars are replaced by outdoor seating and wider pavements. Crime rates in some redesigned neighbourhoods have fallen, possibly because more people are using the streets at different times of day. There may also be psychological benefits: studies in several European cities have suggested that residents of walkable neighbourhoods report higher levels of life satisfaction and stronger social connections than those in car-dependent suburbs.

EThe idea has not been without controversy, however. Some residents complain that road closures cause traffic congestion to spill into surrounding neighbourhoods, increasing pollution in areas that were previously quieter. Drivers' organisations argue that pedestrianisation discriminates against those who must travel longer distances for work, particularly older people and those with mobility difficulties. Small business owners have occasionally protested against the loss of customer parking, although the evidence on this point is mixed and several studies have found that retail spending actually rises after pedestrianisation. More serious is the question of fairness. Critics warn that the 15-minute city could become a privilege of wealthier districts, where investment in cycle paths, parks, and local services is concentrated, while lower-income suburbs continue to lack the same infrastructure.

FThe debate has been further complicated by misinformation. In 2023, conspiracy theories spread on social media claimed that the 15-minute city was a plot to restrict residents' freedom of movement, with some commentators wrongly suggesting that people would be prevented from leaving their neighbourhoods. City planners dismissed these claims as baseless, pointing out that the model is concerned only with making local services accessible, not with limiting travel. Despite such controversies, interest in the approach continues to grow. As cities face mounting pressure from climate change, public health concerns, and rising housing costs, the appeal of designs that prioritise people rather than vehicles seems unlikely to fade. Whether the 15-minute city becomes a global standard or remains a flexible set of local experiments, it has already changed how planners think about urban life.
