sulphur hexafluoride DETERMINATION KEPCO

Sulfur hexafluoride (sf 6) is a much more potent greenhouse gas than CO 2, with an estimated atmospheric lifetime of 800–3200 years. The Intergovernmental Panel on Climate Change found sf 6 to be the most potent greenhouse gas that it evaluated, with a global warming potential 23,900 times higher than CO 2.
