Sources of sulfur dioxide pollution In 1963, more than 23 million tons of sulfur dioxide were discharged into the atmosphere of the United States. The fossil-fueled power plant is the chief contributor to sulfur dioxide emissions and accounts for over 40% of the total emission.
When sulfur (spelled sulphur in some countries) burns with oxygen from the air, sulfur dioxide (SO2) is produced. Coal-fired power plants are the world's biggest source of sulfur-dioxide air pollution, which contributes to smog, acid rain, and health problems that include lung disease.
