States with tremendous oil and natural gas reserves have the most to gain economically from proper regulation.

Greenhouse gas pollution, through its contribution to global climate change, presents a significant threat to Americans health and to the environment upon which our economy and security depends.

When discussing overall impacts on employment, it is important not to overlook the new technologies and industries that can be driven by pollution control standards.

Critics play a dangerous game when they denounce the science and law EPA has used to defend clean air for more than 40 years. The American people know better.

But just [proposing the standard] puts companies on notice that if you're looking to construct a new natural-gas or coal facility, you really need to pay attention to these. This is what they should be designing new facilities toward as soon as this proposal hits the streets.

I cannot shy away from controversy. I don't know if it's my Irish blood, but I love it.

I love disagreements. I love the democratic process. If I'm in a room where everybody agrees, I start to nod off.
