Invasive species as carbon sinks

Spent some time ripping out Japanese bamboo grass with Mary today.  Not as much time as she did, but a little bit. I had never heard of the stuff until a couple of months ago, when I noticed it flourishing in our back yard. Once I had been introduced to it, I couldn't help but to notice how well it grows everywhere along road sides and in woods around here.

Which made me ponder. If species like that and, say, Kudzu, grow so abundantly, does that make them particularly good processors of carbon dioxide and other things plants like and therefore beneficial from the carbon sink perspective, i.e. for soaking up emissions?  I must say I'm curious. But, then again, too lazy to Google, only querulous enough to noodle.
