Mairiporã's air quality benefits from its elevated position in the Serra da Cantareira at 900 metres north of greater São Paulo, with the surrounding Serra da Cantareira State Park providing a substantial forested clean-air buffer. Vehicle emissions from the SP-360 Fernão Dias highway are the primary local concern, while the elevated mountain setting and extensive Atlantic Forest cover generally maintain better conditions than the São Paulo metropolitan average.
