Video Transcript

Well, I think the main problem with conventional automobiles is greenhouse gas emissions. There's also the problem of oil imports, but I worry more about emissions of heat-trapping gases. And if we don't reverse course on greenhouse gas emissions soon, we're going to face catastrophic climate change. A new study, in fact, just came out which basically said we need to peak in global emissions by 2015 to 2020 if we're to avoid catastrophic warming, and then cut emissions 75 percent from current levels. So we're going to have three times as many cars on the road, and if we're going to be reducing emissions by, you know, 75 percent, we're going to need cars that have very, very low emissions of greenhouse gases.
