Afuá: A Car-Free City in the Amazon

The city of Afuá in northern Brazil's Pará state has been off-limits to motor vehicles since 2002, with a focus on bicycles and riverboats for transportation. The mayor, Odimar Wanderley Salomão, aims for the city to be remembered for its net zero emissions. The city faces challenges such as isolation, lack of basic amenities, and reliance on diesel-burning plants for electricity.
