What if your city centre was car-free? In Berlin, people are working to build the largest car-free zone in the world, around 88 square kilometres (an area as large as Turin and its suburb).

At Utopian Hours 2022, the young Nina Noblé will talk about the Berlin Autofrei campaign, an organisation that is pushing for the local government to pass a new law to institute a traffic-free zone in the city – with the aim of encouraging the use of bicycles and reducing urban pollution.
