I would have to come back to you on that. My colleagues John Moffet and Helen Ryan, who have testified before this committee many times, are responsible for the coal reg, and there is a regulatory impact assessment statement attached to our regulations that spells out a rather complete and rigorous analysis of the impacts of those regulations.
The two exist online. The RIAS, as it's known—regulatory impact assessment statement—for the previous regulation and the new one are both available online. I haven't gone through those for the sake of cross-comparison, but certainly we are seeing more emission reductions and sooner.
