Paris en Commun has created a diagram to illustrate the concept of what should be available within 15 minutes of “Chez Moi” (home).

Meanwhile, in Portland, Oregon, walking-distance-limited neighborhood planning is seen as central to climate action: The city aims to cover 90 percent of the city in so-called “20-minute neighborhoods,” where all basic needs—with the exception of work—can be reached within a third of an hour of walking time. In Australia, Melbourne rolled out a similar pilot in 2018.
Hidalgo’s aspirations for Paris build on this idea, but with a local twist. The goal travel time is reduced to 15 minutes, but bike journeys can count. And while it likewise underlines the importance of stores and doctors, it also includes cultural activities and workplaces within its central aspirations.

In Paris, this isn’t necessarily such a tall order. The mayor oversees only the 2.2 million residents of the city’s heavily populated historic core, which already enjoys some of the use-mixing that the 15-minute-city concept encourages, thanks to its pre-industrial roots. Paris would have an easier time with the concept than say, sprawling Melbourne, where more radical residential densification may be in order.
Paris en Commun’s manifesto sketches out some details for what this future walkable, hyperlocal city would look like. More Paris road space would be given up to pedestrians and bikes, with car lanes further trimmed down or removed. Planning would try to give public and semi-public spaces multiple uses—so that, for example, daytime schoolyards could become nighttime sports facilities or simply places to cool off on hot summer nights. Smaller retail outlets would be encouraged—bookstores as well as grocery stores—as would workshops making wares using a “Made in Paris” tag as a marketing tool. Everyone would have access to a nearby doctor (and ideally a medical center), while sports therapy facilities would be available in each of the city’s 20 arrondissements.
Paris en Commun provides some glimpses of what this more self-sufficient, neighborhood-oriented city might look like. The (imaginary) triangular intersection below resembles the current state of many in Paris; there’s some public pedestrian space, but it remains hemmed in by cars, both mobile and parked, and genuinely safe space for pedestrians is limited.
