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.
In 2009, the second-largest source of U.S. carbon dioxide emissions (after fossil fuel consumption) was natural gas production (Figure 16 and Table 16), which includes flaring of natural gas at the wellhead and scrubbing of carbon dioxide from natural gas after it has been produced.
