Reggio Emilia's air quality faces the Po Valley's notorious flat basin topography, with the surrounding Alpine and Apennine ranges creating near-complete topographic enclosure that traps vehicle and agri-food industry emissions under winter anticyclones. Vehicle traffic on the A1 motorway and the surrounding Emilian agri-food manufacturing corridor — including the Parmigiano-Reggiano cheese production operations — generate elevated NOₓ and organic aerosols, while the flat Po plain's persistent winter fog inversions trap all emission sources for extended periods.
