Bremen's air quality is shaped by its position as a North Sea port city in the flat North German plain, with shipping emissions from the Weser river and heavy industrial activity from the ArcelorMittal steel works and surrounding port complex generating elevated PM2.5 and NOₓ. North Sea westerlies generally provide good maritime ventilation, while the flat terrain allows reasonable dispersal on most wind days.
