Sulphur hexafluoride – also known as SF6 – is a ''greenhouse gas'' that has long played a part in global warming, similar to that of carbon dioxide (CO2). CO2 has been a focal point of climate change for many years. Released from the burning of fossil fuels and other carbon-intensive practices, it creates a cover that traps heat from the
