Embu-Guaçu's air quality reflects its position in the southern Greater São Paulo metropolitan ring, with vehicle emissions from the Regis Bittencourt highway and surrounding mixed residential and agricultural character contributing local sources. The Capivari highlands to the south and the Greater São Paulo basin's poor dispersal characteristics affect the southern corridor, while the Atlantic Forest remnants and the rural-urban fringe character provide some clean-air buffering compared to the denser inner metropolitan municipalities.
