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.
A greenhouse gas (or GHG for short) is any gas in the atmosphere which absorbs heat, and thereby keeps the planetâs atmosphere warmer than it otherwise would be. The main GHGs in the Earthâs atmosphere are water vapour, carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O) and ozone.
