Oslo's air quality is generally good, benefiting from the Oslofjord's maritime ventilation and the surrounding boreal forest providing clean air from multiple directions. Winter wood burning in residential areas generates the primary seasonal PM2.5 concern, while vehicle emissions on the E18 and Ring Road 3 corridors contribute sustained NO₂, and cold temperature inversions in the fjord valley can concentrate emissions across the city during still winter periods.
