Caieiras' air quality is significantly influenced by its position in the northern Greater São Paulo metropolitan ring, with vehicle emissions from the SP-332 and surrounding industrial and paper manufacturing operations — Caieiras hosting major paper and packaging production — contributing elevated PM2.5 and organic aerosols. The Greater São Paulo basin's poor dispersal characteristics and the Cantareira hills create the primary air quality influences throughout the year.
