Imagine you live in a town where everyday essentials like work, food, school, health care, and cultural activities all lie within a quick walk or bike ride from people’s homes. Your city has reduced residents’ reliance on car travel, freed you from your hellish commutes, and reconnected communities with one another. Public transit is reliable, concrete expanses have been transformed into lush green space, and carbon emissions are plummeting.
This was the idea sketched by Carlos Moreno, the Sorbonne University professor who pioneered the “15-minute city.” A computer scientist by training, Moreno spent the mid-2000s designing digital energy-management platforms to address urban sustainability. But he became convinced that tech-centered approaches would not solve cities’ problems. He began developing the 15-minute city idea, introducing it at the United Nations’ COP21 Climate Conference in 2015, and working with city leaders to test practices that could bring people closer to their needs and help improve environmental outcomes.
Then came the Covid-19 pandemic, which brought a flood of high-profile attention to the 15-minute city. A group of nearly 100 mayors committed to implementing it in some form as a means toward a climate-friendly recovery from the crisis. At COP26 in 2021, architects put the strategy at the center of discussions of sustainable city development goals. The World Economic Forum released slick videos and articles endorsing the 15-minute city.
It’s probably no wonder, then, that the 15-minute city eventually penetrated the tinfoil hats of the far right. In 2023, climate deniers, QAnon types, radical libertarians, anti-vaxxers, and white supremacists seized on the World Economic Forum’s elite support for the idea. Fringe narratives made it synonymous with “climate lockdowns” and the “great reset,” in which governments would confine residents to open-air prisons, restricting and surveilling their movements (and perhaps forcing them to eat bugs). Online conspiracists compared the 15-minute city to the Warsaw Ghetto. Reactionary self-help author Jordan B. Peterson called it a scheme by “idiot tyrannical bureaucrats” to tell you where you’re allowed to drive. Moreno, in the normal course of events, became a lightning rod for insane abuse and death threats.
Conspiracists have little to fear, as Moreno’s resolutely non-sinister new book, The 15-Minute City: A Solution to Saving Our Time and Our Planet, makes plain. To the decades of poor urban planning that have hastened climate emergency and caused dire “fragmentation,” Moreno poses a utopian solution: “happy proximity.” “We seek to foster mixed-use urban neighborhoods and living spaces that build strong links between people, strengthen social cohesion, and promote a better quality of life,” he writes. The book outlines a moderate program for a sustainable urban future, in which city officials enact incremental policy changes—more bike paths, better public transit, broader green space—that largely rely on private capital and pose little threat to the political status quo. But the thinking behind these features also evokes a more radical egalitarian vision, one that could decentralize work, improve neighborhood solidarity, and help end exploitative economic relationships, expanding our free time and reducing........
