Now, people think,

"Hey, aren't we getting the solar panels and windmills

to be a lot less expensive?

And isn't that helping reduce greenhouse gases?”

And the answer is, absolutely.

But, there's a lot more to do

than just taking electricity to zero emissions.

There's a variety of things

that generate greenhouse gases.

We have a lot of sectors of the economy,

like manufacturing, that are emitting greenhouse gases

that aren't talked about as much.

Manufacturing.

Everything we make even a cute little squishy like this,

that's emitting 21% of the greenhouse gases.

The number of buildings in the world

is going to double by 2060.

It's like we're going to build a new New York City

every month for the next 40 years.

It's a gigantic amount of materials.

Steel, cement, wood, all emitting greenhouse gases.

We're going to have to figure out

how to make all these things in a different way.

And so, we're going to need a lot of change,

a lot of innovation,

to bring the emissions

from all those areas down to zero.
