Technically it's more generally atmospheric 'green-house gases', of which CO2 is the one we produce massive amounts of.
Methane and Nitrous Oxide also play a massive role. We produce less of those mostly through gas leaks and shipping/diesel fuel but they are a lot worse than CO2 if we think of it in terms of per kilo impact.
