California is first to regulate Sulfur Hexafluoride Greenhouse Gas
While coal-fired power plants continue to be the primary target of carbon dioxide regulation, emissions of a lesser known but more potent greenhouse gas from the electric utility industry are being regulated for the first time in California. Sulfur hexafluoride (SF6) is a colorless, odorless, non-toxic, and non-flammable gas that has been used in the […]

SF6: California ARB approves measure to limit most powerful greenhouse gas
SACRAMENTO- Today the Air Resources Board adopted a measure developed with representatives of the electrical utilities that will limit and monitor the emissions of sulfur hexafluoride (SF6) from high-voltage electrical applications. SF6 is approximately 23,900 times as potent as carbon dioxide in trapping heat in the atmosphere: one pound of SF6 emissions is equivalent to […]

U.S. study finds surprise within greenhouse gases
Researchers from NASA and Purdue University found that carbon dioxide and methane are not as important as fluorine (F) compounds such as chlorofluorocarbons, hydrofluorocarbons, perfluorocarbons, and nitrogen fluoride when it comes to producing greenhouse gases (GHGs). The authors of the study are Partha P. Bara, Joseph S. Francisco, and Timothy J. Lee (NASA Ames Research […]
