Hidalgo’s “15-minute city” is a strong break with traditional modern urbanism. Her vision is boldly mixed-use, with employment, commercial, social and cultural activities all existing in close proximity to housing. It’s also been key to helping Parisians adapt to the COVID-19 pandemic, with its focus on opening street space for pedestrians and cyclists. But the city is also bolstering itself against future climate impacts and worsening air pollution as much as against the current crisis.
