If coal wants a place in a carbon-constrained future, they have to look at technology like this. And we think that our rule can help stimulate technology, growth, and innovation, bring those costs down, and allow coal a more stable opportunity to continue to be invested in.

Climate change is the greatest threat of our time.

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.

There is no threshold level of fine particle pollution below which health risk reductions are not achieved by reduced exposure.

We are very confident that the data is showing that carbon capture and sequestration is technologically feasible and it's available. It has been successfully demonstrated and there are full-scale both conventional and unconventional coal projects with CCS that are moving forward. So there is no question that there's continued investment in this technology.

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.

Even if there's controversy, I'm going to make the decision, and people are going to be happy in one instance and unhappy in the next. But that's the job I've been given and the job I'm going to embrace.
