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.

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.
