Lisbon's air quality benefits from its Atlantic coastal position, with consistent westerly winds from the Atlantic and the Tagus estuary providing strong natural ventilation throughout most of the year. Vehicle traffic on the IC19 and surrounding motorway network is the primary local emission source, while the open estuarine geography generally prevents the severe pollution accumulation seen in more topographically enclosed European capitals.
