What's the carbon footprint of the kgbkgb tour?

What's the carbon footprint of kgb's Burning [feeling when you find out you just spent $0.50 on a text that could have been free had you used ChaCha] Questions Tour? Surely there's a huge poof of Co2 tonnage that'll result from driving a 'squard' of Smart Cars through a dozen cities from Dallas to Boston. Instead of issuing a press release on the eve of every single holiday and big sports event to give us yet another reason to use kgb_text for $0.50 more than ChaCha would charge, kgb should announce they're going carbon neutral. How about it?

Update1: the commenter is right - kgbkgb can cost up to $0.99. That's what kgb_text costs an ALLTEL customer!
