Emissions of the powerful greenhouse gas Sulfr hexafluoride are rising

But there’s a problem: it’s also one of the most potent greenhouse gases known to man. The amount of the gas – known as sf6 gas – in the atmosphere is minute, only about three parts per trillion by volume, but its global warming potential is significant. It’s 23,500 times more warming than carbon dioxide.
