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.

Any first-generation technology will. But we are looking at carbon the same way we look at every pollutant under the Clean Air Act; we look for the new technologies that are available. We recognize that these power plants are going to be around for decades.

When consumers do not take full advantage of efficiency gains, it is because they are weighing other factors that influence their decision making. When the federal government arbitrarily places one of those factors over others, it makes consumers worse off.

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.

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 think climate change is probably the most extreme, and it's been going on for years because it's very difficult to talk about a planetary issue like climate change and to get people who live within four-year electoral cycles to actually pay attention to something that you predict is happening way in the future.
