That's your opinion and you're entitled to it. But, the overwhelming majority of people who are educated in the matter would disagree with you, and that doesn't by default make them idiots.

I agree with the rest of your post though, and whether carbon dioxide is a legitimate problem or not, there's increasing pressure on big businesses to reduce their CO2 emissions. Not just from the government agencies but consumers too.
Celebrities in particular would would love to portray a "green" image as they pull up to a G5 in their Prius. Even if it's just a placebo.
