Sulphur dioxide enters the atmosphere as a results of both natural phenomena and anthropogenic activities, such as fossil fuel combustion, oxidation of organic materials in soils, volcanic eruptions and biomass burning.

These pages presents highlights of SO₂ emissions related to volcanic eruptions and anthropogenic activities.
