Also, it depends on where the CO2 came from. If they extracted it from the air to put in the soda, then you aren't adding any to the air, you are just holding onto some that was already there for a while.
But you can stop if you like. Carbonated sodas are really bad for your teeth too, which is another reason not to drink them.
The CO2 that is used to carbonate both soft drinks and alcoholic ones is either extracted directly from the air or, as is becoming more common, it’s recovered from the emissions of other processes such as power generation.
Drink as much soda and beer as you want, the bubbles aren’t going to add any more CO2 to the atmosphere.
CO2 in beverages is a byproduct of other industrial processes. No carbon is moved from the ground to the air, is it is when we burn stuff.
Do you even know how much CO2 there is in a coke can:
2.2g CO@/liter

Why would you compare one can of soda to a coal power plant?
Coca-Cola produces more than 4 billion cases of soft drinks per year. That's a lot of soda!

4 billion times 2.2g/liter
4000 0000 000 * 2.2g/liter = 2200000000000 g/liter per year CO2
My math might not be right, but you get the point. Soda CO2 for just one company per year is 2200000000000 g/liter.
Your on the right track, if CO2 is the problem then the more things you eliminate in your life that result in the emission of CO2 the better. If everyone who believed CO2 was the problem reduced their consumption then industry would have to reduce their production reducing emissions. It is that simple, but it's easier to blame everyone else instead of taking action on your own plus its not fair if everyone else is doing things that you've stopped doing.

Get real
As Bacc & Trev said this CO2 is a byproduct of industry or extracted from the air, so it would be in the atmosphere either way so drinking soft-drink (soda) makes no real difference.
