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.

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.
