Depends on your understanding of the term "biggest":

  • The largest volume of naturally occurring greenhouse gas is water vapour.
  • The largest volume or tonnage of manmade greenhouse gases is carbon dioxide.
  • The most potent is Sulfur Hexafluoride (SF6) which has a greenhouse gas impact 23,900 times that of carbon dioxide.

Water vapor. Carbon dioxide is second, by volume. Methane and others are more potent, pound for pound, but there is not as much of them. Increasing CO2 is responsible for climate change, per most climatologists.

How do you know whether a gas is greenhouse gas i.e how a greenhouse gas is different from non-greenhouse gas?

A greenhouse gas is a gas (with at least three atoms) that traps heat inside the earth's atmosphere. Greenhouse gases include carbon dioxide and methane. It is important that some heat is trapped inside our atmosphere - otherwise the earth would freeze. But too much heat has a negative impact on the climate.


Is radon an example of greenhouse gas?
