Atibaia's air quality benefits from its elevated position in the Serra da Cantareira foothills at 765 metres in northern greater São Paulo, with the Atlantic Forest mountain setting providing cleaner background air than the metropolitan core. Vehicle emissions from the SP-063 Fernão Dias highway and the surrounding floriculture, technology research, and weekend residential corridor contribute local sources, while the elevated position and the Cantareira's forested backdrop generally maintain better conditions than the São Paulo metropolitan average throughout most of the year.
