Halden's air quality reflects the Iddefjord position at the Norway-Sweden border, with vehicle traffic on the E6 and surrounding industry and logistics operations contributing local sources. Consistent Atlantic and Skagerrak westerlies provide reliable ventilation, while the surrounding Halden forests provide reasonable dispersal and the border crossing character generates some concentrated freight vehicle emissions throughout the year.
