At the same time that we're solving for climate change,

we're going to be building cities for three billion people.

That's a doubling of the urban environment.

I'm not sure all the climate solutions in the world will save mankind,

because so much depends on how we shape our cities:

our sense of community and connectedness.

Fundamentally, the way we shape cities is a manifestation

of the kind of humanity we bring to bear.

And to a certain degree, getting it right can help us solve climate change,

it's our behavior that seems to be driving the problem.

and it isn't just ExxonMobil and oil companies.

It's called sprawl, and I'll be upfront about that.

But it's not just the kind of sprawl you think of, or many people think of,

out at the periphery of the metropolitan area.

Actually, I think sprawl can happen anywhere, at any density.

The key attribute is that it isolates people.

It segregates people into economic enclaves

It doesn't allow the cross-fertilization,

So the antidote to sprawl is really what we all need to be thinking about,

especially when we're taking on this massive construction project.

We developed the model for the state of California

so they could get on with reducing carbon emissions.

We did a whole series of scenarios for how the state could grow,

and this is just one overly simplified one.

We mixed different development prototypes

and said they're going to carry us through the year 2050,

10 million new crew in our state of California.

It's just more of the same: shopping malls, subdivisions,

The other one was dominated by, not everybody moving to the city,

what we used to think of as streetcar suburbs,

low-rise, but integrated, mixed-used environments.

They're astounding not just for the scale of the difference

of this one shift in our city-making habit

but also because each one represents a special interest group,

a special interest group that used to advocate for their concerns

They did not see the, what I call, "co-benefits" of urban form

environmentalists are really concerned about this,

and, of course, neighborhood groups that want open space nearby.

almost doubles the urban physical footprint.

because in California, our biggest carbon emission comes from cars,

and cities that don't depend on cars as much

Vehicle miles traveled: that's what I was just talking about.

Just reducing the average 10,000 miles per household per year,

from somewhere in the mid-26,000 per household,

has a huge impact not just on air quality and carbon

the middle class is struggling to hold on.

Health care: we were talking about how do you fix it once we broke it --

Why not just use our feet and bikes more?

And that's a function of the kinds of cities that we shape.

not of just the financial industry running amok.

It was that we were trying to sell too many of the wrong kind of housing:

too expensive for the average middle-class family to afford

and, quite frankly, not a good fit to their lifestyle anymore.

you can discount the financing and get it sold.

remember, in California the median is 50,000 --
