SF6 Emission Reduction Partnership for Electric Power Systems

2005 Annual Report (August 2006, Revised). Sulfur hexafluoride (SF6) has been identified by the Intergovernmental Panel on Climate Change (IPCC) as the most potent non-CO2 greenhouse gas, with an ability to trap heat in the atmosphere 23,900 times more effectively than CO2. 
Approximately 80 percent of SF6 gas produced is used by the electric utility industry in high voltage electrical equipment as an insulator or arc quenching medium.2 Currently, more than 80 environmental leaders in the U.S. electric utility industry are recognized by EPA under the SF6 Emission Reduction Partnership for Electric Power Systems for actively targeting SF6 emissions. Partners are proactively helping to prevent global climate change and in doing so, are experiencing operational and cost efficiencies through improvements to equipment reliability and reduced SF6 gas purchases and maintenance expenditures.
