Top answer

Depending on context, the percentage (or ppm figure) might be the useful or expected answer, but "how much" is not specific in that respect. With no more information, "3 trillion tonnes" would also be a valid answer (figure taken from some random website). It is written CO 2 (or CO2 if subscripts are not available), not co2.

Sorry for disturbance >< (I'm working on a document about CO2 emission now).
Does the amount of CO2 emission sound odd? When you want to say about the quantity of it, what do you say?

Oh dear, I seem to be having a blank about this question. Could someone else answer? Failing that, please start a new thread.
