Carbon dioxide tends to dominate conversations about greenhouse gases.
And while CO₂ accounts for roughly 74% of total emissions, according to the Center for Climate and Energy Solutions, it is by no means the most potent of these gases.
Methane, which is at least 80 times more damaging than carbon dioxide over a 20-year timeframe, is increasingly being addressed by climate action campaigns.
But even the harmful potential of methane is dwarfed by a lesser-known greenhouse gas – sulphur hexafluoride, more commonly referred to as SF₆.
SF₆ has been used in energy grids for decades to insulate electricity and extinguish high-voltage electric arcs, preventing fires and damage to equipment.
