How major cities tackle air pollution globallyTL;DR: Urban air pollution is a major challenge, driven by vehicle emissions, industrial activity, and population density. Cities worldwide are adopting low-emission zones, green infrastructure, and public transit improvements to combat pollution. Sustainable urban planning, including bike-sharing, pedestrian zones, and renewable energy, plays a crucial role. Technological advancements, like air quality sensors, support data-driven policies. Global efforts highlight the need for continued innovation and commitment to sustainable city development.
