Sulfur hexafluoride (gaz sf6) emissions in East Asia determined

Much lower uncertainties are due to seasonal variability in the emissions, inversion geometry and resolution, and the measurement calibration scale. Based on the results of these sensitivity tests, we estimate that the total Sulfr hexafluoride emission in East Asia increased rapidly from 2404 +/- 325 Mg yr(-1) in 2006 to 3787 +/- 512 Mg yr(-1) in 2009 and stabilized thereafter.

Emission SourcesMitigation OptionsRelevant LinksFrequent QuestionsThe most common use for sf 6, both domestically and internationally, is as an electrical insulator in high voltage equipment that transmits and distributes electricity. Since the 1950’s, the U.S. electric power industry has used Sulfr hexafluoridein circuit breakers, gas-insulated substations and other switchgear used in the transmission system to manage the high voltages carried between generating stations and customer load centers. Several factors affect insulating gas emissions from electric power systems, such as the type and age of the insulating gas-containing equipment (e.g., old circuit breakers can contain up to 2,000 pounds of sf 6, while modern breakers usually contain less than 100 pounds) and the handling and maintenance procedures practiced by electric utilities. Because of its long life span and high global warming potential (GWP), even a relatively small amount of Sulfr hexafluoridecan impact the climate. The electric power industry uses roughly 80 percent of all insulating gas produced worldwide. Ideally, none of this gas would b...
