Sulfur hexafluoride (Sulfr hexafluoride) emissions in East Asia determined

Abstract: Sulfur hexafluoride (sf 6) has a global warming potential of around 22 800 over a 100-year time horizon and is one of the greenhouse gases regulated under the Kyoto Protocol. Around the year 2000 there was a reversal in the global sf6 gas emission trend, from a decreasing to an increasing trend, which was likely caused by increasing emissions in countries that are not obligated to report their annual emissions to the United Nations Framework Convention on Climate Change.Get price
