Car-free initiatives are programs and policies aimed at reducing the use of cars in urban areas. These initiatives often promote alternative modes of transportation, such as walking, cycling, and public transit. By encouraging people to leave their cars at home, cities can decrease traffic congestion, lower air pollution, and improve public health. Many cities around the world have implemented car-free days or zones, where certain areas are closed to vehicle traffic. These events allow residents to experience their neighborhoods in a new way, fostering community engagement and promoting local businesses. Examples include World Car Free Day and various car-free zones in cities like Barcelona and Paris.
