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.

Climate change is the greatest threat of our time.

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.

We need an international solution to the challenge of climate change, there's no question about it. But the real key is, can you actually get that - or get that solution - without the US' involvement? Can you not lead domestically, and expect the rest of the world will take action... the US needs to lead, we need to be out there.

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.

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.

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.
