Caçapava's air quality reflects the Paraíba do Sul river valley on the São Paulo-Rio de Janeiro industrial corridor, with vehicle emissions from the Via Dutra and the surrounding Embraer and aerospace supplier manufacturing operations contributing elevated industrial and vehicle emissions. The valley's topographic enclosure between the Serra da Mantiqueira and Serra do Mar concentrates industrial and vehicle emissions under calm conditions in this strategic aerospace corridor.
