We all say things when we are trying to get elected.

How are we going to know what impact that has on the greenhouse gas emissions? How are we going to hold everybody accountable for doing their part?

We have the resources the world needs. We can build a path for them to get there. That's that delicate balance that we find.

I think we should be worried about the fact that we have become, as a society, very focused on the way people look, the way they dress. I do think we should worry about that because we should be worried about content. We should be worried about ideas. We should not be putting form over function.

Here Hillary Clinton is probably the most qualified person based on experience to ever run for president of the United States, and then this guy gets into the race, Bernie Sanders, and suddenly everybody goes, "Look at him. He's a real contender - "

I have a broad view that we have to try and get to "yes" on projects. On economic projects anybody can say no. My child can say no. But I think the hard thing to do is to figure out how you get to "yes" and you protect the environment.

We know taxes slow down economic growth, so if you add a carbon tax you have to also minus other taxes. You can't take more money out of people's pockets. I don't think you can build a consensus in this country about environmental policy if you're going to make people poor.
