Lima introduced one day a month where all motorized transport is banned from the historic city center of Lima, opening and cleaning up the streets for pedestrians.
Lima had the most polluted air in Latin America in 20141, with motor vehicles cited as the main cause. By freeing the streets from dangerous smog once a month, the city hopes to raise awareness of the problem and change transportation habits.
For 12 hours on the last Sunday of every month, the Peruvian capital city has created a ban for vehicles in the old and central district. This road closure promotes more sustainable transport alternatives and is also used as a chance to create artistic, educational, and gastronomic activities for the city's citizens and tourists. It also serves as respite for the air pollution caused by traffic during the remainder of the month. To further encourage walking and cycling in the city, Lima offers free cycling workshops and has created additional cycle routes. And to determine the difference created by the scheme, the city regularly measures air particulates as well as noise levels. Particulate levels more than halved during one of the car-free days and noise levels fell from 78 to 59 decibels, creating a cleaner, calmer, and healthier environment for all to enjoy.
Environmental Benefits – Preventing cars from entering the city center not only reduces air and noise pollution, but also cuts greenhouse gas emissions from cars.
Social Benefits – Taking cars off the road allows more space for socially inclusive activities. The city estimates that the free cycling workshops and entertainment have benefited more than 7,000 people.
Health Benefits – Lima is taking its first small step in reducing air pollution, showing what sort of environment is possible when cars are absent and more people cycle.
