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.

I don't think any administration, when they come in, thinks that their job is to tell the scientists what the science looks like or to be quiet about the science. Scientists need to remain true and not allow science to be politicized. Scientists are not politicians, and no politician should consider themselves to be a scientist.

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

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.

People are not running to build coal facilities because of the price of natural gas, but we do see them being constructed, and there is an interest in fuel diversity, so we took the exercise pretty seriously.

Climate change is the greatest threat of our time.

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.
