What is causing poor air quality in Milan?
Milan’s poor air quality is driven by a mix of regional and local factors. The city’s location in the Po Valley exacerbates the problem by trapping industrial emissions, traffic pollution, and agricultural runoff—conditions that intensify in winter due to stagnant air and temperature inversions, which prevent pollutants from dispersing (1).
