From Bogotá to Kigali, cities worldwide are proving one simple policy can cut emissions, boost health, and bring communities together.
More cities are discovering that regularly closing streets to cars - even for a few hours - can transform urban life.
Here’s what happens when we make space for people instead of traffic:
🌍 Cleaner air & lower emissions
Less NO₂, fewer particulates, and a break for the planet.
🚶 Healthier, safer streets
More walking, cycling, and jogging. Fewer traffic accidents. Less stress from noise.
💡 Thriving local economies
Shoppers on foot and bike spend more locally. Public spaces turn into markets, performances, and community hubs.
🌳 Cooler, more liveable cities
Greener streets fight heatwaves. Flexible spaces help in emergencies and climate adaptation.
And the best part? It works.
🌍 Here are 6 cities making car-free streets work:
1. Bogotá, Colombia – Ciclovía

2. Paris, France – Journée Sans Voiture
- Annual citywide car-free day + ongoing district restrictions.
- Impact: 30–40% drop in NO₂; more long-term pedestrianisation.

- Impact: 30% less central traffic; CO₂ cut by 35%; more cycling infrastructure.
6. Kigali, Rwanda – Monthly Car Free Day
- Held twice a month with fitness activities and health checks.
