On 23 March 2026, Zurich recorded elevated particulate matter levels in the air, leading authorities to issue an environmental alert for the city region.

Health officials advised residents with respiratory issues, the elderly, and children to limit outdoor activities and to keep windows closed during peak pollution hours. The event prompted renewed calls for traffic reduction measures and stricter emission controls in densely populated urban areas.
