Dr. Paul Crosson:

In terms of the carbon piece, it is important to remember that in terms of the overall relative emphasis, within the terminal index, 6% is due to carbon. In the replacement index, 10% is due to carbon, the carbon economic values. In other words, 90% is due to conventional economics. Regarding the economic values themselves, 13% of them are carbon. I do not want to bamboozle the Deputy with numbers, but just to give him an indication, the point is that approximately 90% of the total changes in economic values are non-carbon. That being said, carbon is important and Mr. Coughlan has outlined the rationale and the overall driver for this.
