São José dos Campos' air quality reflects its position as a major aerospace and automotive industrial hub in the Paraíba do Sul valley between São Paulo and Rio de Janeiro, with Embraer, General Motors, and surrounding manufacturing plants contributing industrial emissions alongside heavy traffic on the Presidente Dutra highway. The valley topography between the Serra da Mantiqueira and Serra do Mar creates partial enclosure that can concentrate emissions on calm days.
