A TV ad for Saab BioPower was yanked off the air in the UK for tying bioethanol to reduced carbon output. According to the UK's Advertising Standards Agency, Saab's "Release Me" commercial (watch it below the fold) incorrectly states that using bioethanol-capable cars reduces your carbon footprint. The ad said carbon is reduced thirty percent when you drive with bioethanol. Unfortunately for Saad, it's closer to carbon neutral if you measure from seed to tail pipe. However misleading the ad campagn, I think the "more horsepower and a smaller carbon footprint" idea is very compelling.
