I am marking exam papers and all of a sudden I have come to worry about abbreviations. Is is correct to write CO2 (carbon dioxide) in a text? The student is supposed to write a speech on climate changes.
What would you say when delivering the speech? CO2 or carbon dioxide?

Dear Mulle
I would say carbon dioxide as CO2 sounds the way it �s normally said in DK.

Dear Mulle, I accept that in an informal language context, which is not the case. I would underline CO2.
Good work.

I have something of a Science background and I �d say that they �re both correct, with the following comments:
CO2: If you �re addressing a scientific audience, you �d be more likely to use abbreviations such as this.
Carbon dioxide: It sounds more formal, but you wouldn �t want to have to repeat it too often - you �d be more likely to switch to CO2 (3 syllables vs. 5) after the audience is clear that you �re talking about carbon dioxide (in the case that they are not familiar with the term).
