Campus carbon neutrality 11, 1997 and put into practice on February 16, 2005. The protocol targets industrialized countries because they are the ones producing most of the greenhouse gases. Specific chemicals that it wants to reduce are carbon dioxide, methane, nitrous oxide, Sulfur hexafluoride, hydrofluorocarbons, and perfluorocarbons. Thirty-seven industrialized countries and parts of Europe have signed and are bound by the agreement. The United States is not one of them. The Kyoto Protocol allots a specific amount of greenhouse gas emissions that each country can produce, however, countries can also trade emissions with other countries, resulting in the cap and trade system.

Sulfur dioxide a versatile inert solvent widely used for dissolving highly oxidizing salts. It is also used occasionally as a source of the sulfonyl group in organic synthesis. Treatment of aryl diazonium salts with sulfur dioxide and cuprous chloride yields the corresponding aryl sulfonyl chloride, for example: Injections of sulfur dioxide in the stratosphere has been proposed in climate engineering. The cooling effect would be similar to what has been observed after the large explosive volcano eruption of Mount Pinatubo in 1991. However this form of geoengineering would have uncertain regional consequences on rainfall patterns, for example in monsoon regions. Sulfur dioxide
