How will we power our future? Can we create a healthy and clean economy?

Climate One at the Commonwealth Club is at the forefront of the global debate about energy, economy, and the environment.

Bringing together the brightest and most provocative leaders of our time,

Climate One is the place where big ideas get heard.

With thoughtful and insightful discussions on policy, business, science, and culture,

Climate One founder Greg Dalton gets to the heart of the matter. It's our future. It's time to come together.

Welcome to Climate One in conversation about America's energy, economy, and environment. To understand any of them, you have to understand them all. I'm Greg Dalton.

Today we're discussing a new means of personal mobility. A few decades ago, if you didn't have a car and there wasn't a bus nearby, you might have had to stick your thumb out on the side of the road. Today, you can employ your fingers by opening a smartphone app and finding a ride across town or across the country. If you want to drive, you can do that too, and a car owned by a company or a neighbor.

Over the country. If you want to drive, you can do that too, and a car owned by a company or a neighbor.

Over the next hour, we'll discuss the transportation piece of the sharing economy with our live audience here at the Commonwealth Club in San Francisco.

We're pleased to have with us four people who are at the forefront of these innovations.

Rick Hutchinson is CEO of City Car Share.

Sineal Paul is CEO's side car, a ride-sharing company in San Francisco, and a handful of

other cities.

We also have with us, Susan Shaheen, co-director of the Transportation and Sustainability

Research Center at UC Berkeley.

And we also have Kristen Sfercheck, the head of public policy at Lyft and Zim Ride.

Please welcome them to Climate One.

I'd like to start briefly by asking you how you kind of got into this part of the sharing economy and

car sharing. And Susan Shaheen, you've been doing this a very long time. Tell us briefly how

you got into this new area quite some time ago. So I've been researching car sharing and shared

use vehicle systems for about 17 years, which seems like a really long time.
