California Caps SF6 Emissions for Utilities

The California Air Resources Board recently announced that they will begin monitoring and limiting the emissions of sulfur hexafluoride (SF6) in high-voltage electrical equipment starting in 2011. SF6 is the most potent of all greenhouse gases which contribute to climate change. SF6 is approximately 23,900 times as potent as carbon dioxide, the world’s most prevalent greenhouse gas, at trapping heat in the atmosphere.
