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.
Methane, which comes from natural gas, landfills and cow flatulence, is one of the top three greenhouse gases, according to the Popular Science website. Methane has a Global Warming Potential (GWP) rating of 21.ethane, which comes from natural gas, landfills and cow flatulence, is one of the top three greenhouse gases, according to the Popular Science website.
