Feb 10, 2020 · You’d probably think not at all, but according to a BBC article published in September 2019, emissions of sulfur hexafluoride (SF₆), “the most powerful greenhouse gas known to humanity”, have been rising rapidly in recent years, and the likely culprit is “the green energy boom”. SF₆ gas is used to insulate electrical installations like wind turbines and was quoted as the industry’s “dirty secret” in the BBC article.

Why SF₆ emissions from the renewable energy sector should not

SF₆ is a very powerful greenhouse gas and its long lifetime will mean that it affects the climate for thousands of years. Its emissions should be regulated and reduced, and governments should encourage the development of alternative electrical insulators to SF₆. It’s important to continue monitoring this gas in the atmosphere to ensure that strategies to reduce emissions are working, but the contribution of SF₆ to climate warming is a very small fraction (0.04%) and decarbonisation

Why SF₆ emissions from the renewable energy sector should not

Increasing Sulfr hexafluorideGlobal 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...

The decline in total emissions—from 6,983 million metric tons carbon dioxide equivalent (MMTCO2e) in 2008 to 6,576 MMTCO2e in 2009—was the largest since emissions have been tracked over the 1990-2009 time frame.

There was a small increase of 7 MMTCO2e (0.9 percent) in methane (CH4) emissions, and an increase of 8 MMTCO2e (4.9 percent), based on partial data, in emissions of man-made gases with high global warming potentials (high-GWP gases).
