Ozone Alarm 2025 in the Balearic Islands: Heat, Traffic and the Question of Effective Countermeasures

Answer

Why is Palma especially affected by ozone in summer?

Palma combines heavy traffic, delivery vehicles, urban heat and strong summer sun, which creates good conditions for ozone formation. Busy roads and stop-and-go traffic can add more emissions, while dark surfaces and limited shade make the city heat up faster. That makes ozone peaks more likely in central parts of the city.
