There was some question in this thread about what exactly John Edwards means when he says he would "require that all new coal-fired plants be built with the required technology to capture their carbon dioxide emissions." Would he require that new coal plants sequester their emissions, or merely that they be built in such a way that they could sequester their emissions at some point in the future?
I called the Edwards campaign today. The answer is the latter: the ban would not require coal plants to sequester their emissions; it would merely require compatibility.
This is enormously significant difference. More later.
