Paris builds its smart city around citizens and the street, not around a control room. From the contactless Navigo pass and the Vélib' bike-share to participatory budgeting, low-emission zones and a river made swimmable again, its digital tools stay in service of a visible improvement to daily life — under the political banner of the ville du quart d'heure.
The atlas documents 13 projects in Paris, the earliest dating to 2001: 2 with a documented success, 1 documented failure, 10 still running without a verdict. Every entry carries an evidence grade — the strongest here is independent (3 entries) — and links its sources.
Three entries that show what Paris is actually doing.
Computed from the 13 entries below — a profile, not a score.
Before the civic-tech headlines, Paris was quietly wiring its everyday infrastructure and, tellingly, sharing it. The regional Navigo contactless pass replaced the magnetic Carte Orange from 2001, and in 2007 Vélib' put one of the world's largest bike-shares on the street — an idea copied by cities everywhere. The 2011 wave was more mixed: the Paris open-data portal opened the city's datasets under a free licence, a citywide connected street-lighting programme began remote-managing some 200,000 light points, and Autolib' launched a pioneering all-electric car-share — which grew large but collapsed in 2018 under a €293M deficit, an early lesson that a smart-mobility scheme can fail on economics rather than technology.
The next moves were pure civic-tech. In 2012 the city launched Dans Ma Rue, an app that lets residents report a broken bench or an overflowing bin straight into the city's work orders, and in 2014 it opened its Budget Participatif, handing residents a real vote over hundreds of millions of euros of investment — one of the largest participatory-budgeting programmes anywhere.
From around 2017 the story turned to climate adaptation and reallocating road space. The Cours OASIS programme began converting asphalt schoolyards into cooler, greener heatwave refuges, and the 2021 Plan Vélo laid down a digitally-monitored cycling network that made bikes a mainstream way to cross the city. Alongside them ran less visible infrastructure: the Grand Paris low-emission zone (from 2019) used France's Crit'Air stickers to phase out the dirtiest vehicles — though automated enforcement was repeatedly postponed and, in 2025, MPs even voted to scrap the scheme — while Eau de Paris fitted its drinking-water network with quality probes and thousands of acoustic leak sensors feeding a data lab. The technology was rarely the headline; the livability was.
The through-line came together in 2024 with Seine bathing-water sensing, where real-time water-quality monitoring backed a very public promise: that Parisians would swim in their river again. It is the clearest expression of how Paris uses smart-city tools — quietly, in service of a visible improvement to daily life — under the political banner of the ville du quart d'heure, the 15-minute city.

Plans and announced trajectories — not yet documented results.
The next chapter is mostly about keeping those promises and resolving the tensions the arc exposed: opening permanent public swimming sites on the Seine after the 2024 Olympics, extending the OASIS and cycling networks, and deciding the fate of the low-emission zone now caught between tightening rules and political retreat. Paris's bet is that the smartest city is the most liveable one, and its coming projects are likely to keep measuring themselves by that yardstick rather than by the number of sensors installed.
Where Paris appears in the atlas's own analysis.
Three cities the atlas reads next to Paris — the reason first, then the entries it rests on. Chosen by hand from the Paris threads below, not counted out of them.
Two city halls that treat public space and participation as one project, and that keep arriving at the same idea within a season of each other: docked bike-share, an open-data portal, greening paved ground, participatory budgets.
The two capitals that ran the same programme four times over — an open-data portal, a citywide participatory budget, a politically contested low-emission zone and a docked bike-share — each within a few years of the other.
Two capitals running the same utility stack at the same scale: hundreds of thousands of tele-managed light points apiece, acoustic sensors hunting leaks in old mains, and a contactless fare that arrived by different routes.
Every editorial link from Paris's entries into another city, strongest first. Each one is a statement about two projects, not about two cities — the three above are the ones the atlas is willing to make at city level.
