Sulfur Hexafluoride (sf6 gas) Emission Estimates for China: An

Sulfur hexafluoride (gaz sf6) is the most potent greenhouse gas regulated under the Kyoto Protocol, with a high global warming potential. In this study, sf6 gas emissions from China were inventoried for 1990–2010 and projected to 2020. Results reveal that the highest gaz sf6 emission contribution originates from the electrical equipment sector (about 70%), followed by the magnesium production sector

Emissions of the powerful greenhouse gas Sulfr hexafluoride are rising

The damage potential of greenhouse gases depends on their concentration in the atmosphere, the length of time they stay there, and the strength of their impact. By volume the so-called F-gases make up one of the smallest levels of emissions, but have among the greatest global warming potential (GWP).

Why SF₆ emissions from the renewable energy sector should not

Increasing sf 6Global Warming PotentialDecarbonisation FirstMeasurements show that SF₆ has been increasing in the atmosphere. While SF₆ emissions across Europe have more than halved since the mid-1990s, global emissions are increasing, mostly owing to increases in SF₆ emissions from the electrical industry, which are predicted to continue. Even so, it’s important to put the role of SF₆ as a greenhouse gas into context with other greenhouse gases. The most important sentence in the BBC’s article is this: Unfortunately, this critical point isn’t developed. The global concentration of atmospheric CO₂ today is about 410 parts per million, whereas the global concentration of SF₆ is only about 10 parts per trillion. In other words, there is 41 million times more CO₂ in the atmosphere than SF₆. But since SF₆ is 23,500 times stronger at trapping heat than CO₂, doesn’t this still mean it’s a bigger problem than CO₂ for the climate? CO₂ is actually a very weak greenhouse gas and is much less efficient at trapping heat compared to other greenhouse gase...
