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.
Water vapor is the most commonâ¦ greenhouse gas, but man has no control over its levels. Carbon dioxide, the high levels of which we are responsible for, is having the largest effect on the recent increases in global temperature.   A: The most common greenhouse gas for the natural greenhouse effect is water vapour.
