Answer Wiki. It turns out that sulfur hexafluoride, SF6, is the most potent greenhouse gas ever measured. Greenhouse gas potency is measured with an unit called the GWP or global warming potential, and it takes in account the molecule's ability to absorb infrared radiation and survival in the atmosphere. SF6 is an octahedral molecule, with six S-F bonds, each capable of absorbing infrared radiation very well.
Take a look at this picture. It is the most poisonous substance known to man. A couple of teaspoons would be enough to kill everyone in the UK. A couple of kilos would kill every human on earth. It is so dangerous that it is manufactured in military installations and at around Â£100 trillion per kilo it is also the most expensive substance ever made.
