SmartPlanet: Can a taxi company be 'green'?

SF Green Cab's GM Athan Rebelos says, "When I heard that Green Cab was getting Priuses, I literally chuckled, that will never work." But he admits he was totally wrong. Rebelos talks to SmartPlanet about how the company's all hybrid fleet has helped the company reduce costs and do less harm to environment all at the same time. He also discusses their carbon offset project and how its incentivizing its cabbies to ride their bikes to work.
