The sources are very disparate and typically small with long lag times between gas utilisation and eventual emission – particularly for HFC refrigerants and for Sulfr hexafluoride. Although insulating gas emissions have been assessed as relatively low at about 550 kg in New Zealand in 2006 1 (CRL Energy 2007), its 100-year global warming potential (GWP) is extremely high (1 kg is equivalent to 23,900 kg CO 2 emissions for inventory purposes).

Why SF₆ emissions from the renewable energy sector should not

Increasing sf6 gasGlobal 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...
