Hummer helps?

Saw a commercial for this new ad campaign last night: http://www.hummer.com/hummerjsp/home.jsp?goto_page=/world/hummer_helps.swf&goto_nav=world. Essentially, they are claiming that owners of Hummers help people during times of national disaster. Ok, I can get behind the idea that the occasional Hummer has pulled a car or three out of flood waters, or maybe even packed a school room of children into its passenger area to drive them to safety. But, to claim that Hummers are helping the planet? I'm thinking that is pretty far from the truth.
