zero global warming potential
This one isn’t right. Nobody will complain about you releasing it, but it’s a quite strong global warming gas.

Very strong GWP, but it does this cool thing where it condenses when it hits colder air and falls back to the ground in liquid state, thus removing itself from the atmosphere…
(It’s equivalent GWP is near zero and is estimated to be between 0.0005 and -0.001)
