Do you always read this as "carbon dioxide" or "See Oh Two" as well? I think the same goes for H20 meaning water.
GO2-12)A flight between London Heathrow and New York's John F Kennedy airport creates around 1.35 tons of CO2 per passenger - more than one-third of the yearly emissions of an average person worldwide.

I would read it as "see-oh-two" as well, especially if reading it aloud. If, however, I was trying to explaining the concept to someone who might not know the chemical elements, I would probably call it carbon dioxide. We read and see CO2 much more frequently than H2O, unless we are in a scientific environment. CO2 has only become relatively well-known due to environmental/green issues.
Remember - correct capitalisation, punctuation and spacing make posts much easier to read.
I think most people are savvy enough to understand what "H2O" is. (It's what you mix with your C2H5OH.)
Yeah, but that's just fizzy sugar-water.
Reminds me of the epitaph:
"Alas, poor Fred, he is no more
For what he thought was H2O was H2SO4!"
PS: H2SO4 = Sulphuric acid.

To say nothing of the K9P joke (low quality of water - you can roll your own )
