The Role of Sulfur Dioxide Aerosols in Climate Change .

26/5/2015· It is unfortunate, but further actions to reduce SO2 emissions, especially by the EPA, and in Eastern Asia, can be expected to cause ever-increasing temperatures. Since CO2 has been shown to have no climatic effect, all efforts to reduce CO2 emissions in hopes of controlling global warming will be a waste of resources.

Industrial Emissions | Air Pollution | Sulfur Dioxide

Emissions of SO 2 are proportional to the sulphur content of the fuel, although with regard to coal a proportion, usually less than 10%, is retained in the ash. Therefore, one of the simplest ways to reduce the amount of SO 2 released from the combustion process can be achieved by switching to a fuel that has a lower sulphur content, i.e. burning low sulphur coal or gas instead of high sulphur ...
