'Dirty Secret' Gas Boosts Climate Warming
The most powerful greenhouse gas you've never heard of.
It's the most powerful greenhouse gas known to humanity, and emissions have risen rapidly in recent years, the 大象传媒 has learned.
Sulphur hexafluoride, or SF6, is widely used in the electrical industry to prevent short circuits and accidents.
But leaks of the little-known gas in the UK and the rest of the EU in 2017 were the equivalent of putting an extra 1.3 million cars on the road.
It's an incredibly destructive greenhouse gas, that can seriously damage the atmosphere.
Sulphur Hexa-fluoride, also known as SF6, is used to prevent fires and accidents in electrical equipment, in power stations and wind turbines.
But if it leaks the consequences for the environment are severe, and levels of SF6 in the atmosphere have increased sharply in recent years.
Across the EU leaks have been equivalent to the emissions of 1.3 million extra vehicles on the road in just one year. Matt McGrath investigates, what's behind the rise.
