Robin Chase on Zipcar and her next big idea #Ted

Robin Chase founded Zipcar, the world’s biggest car-sharing business. That was one of her smaller ideas. Here she travels much farther, contemplating road-pricing schemes that will shake up our driving habits and a mesh network vast as the Interstate.

With Zipcar, Robin Chase introduced car-crazy America to the concept of non-ownership. Now she's flipping that model with Buzzcar, which lets you rent your own auto to your neighbors.

"We need to reduce CO2 emissions in 10 to 15 years by 80 percent in order to avert catastrophic effects. … What are catastrophic effects? A three degree centigrade climate change rise that will result in 50 percent species extinction.” (Robin Chase)
