Sulfur Dioxide (SO₂) Emission Trends

Sulfur dioxide, or SO2, belongs to the family of sulfur oxide gases (SOx). DNR provides more information on SO2 and its human health and environmental effects on the following web page: Sulfur Dioxide.

ECPP participants have reduced SO2 emissions by nearly 40% from baseline levels. This accomplishment has happened at a time when SO2 emissions at all other stationary sources in Wisconsin have remained relatively constant.
