We didn't go through the analysis. There are 14 sectors. We noted there were several hundred industrial installations—it's probably closer to 2,000. Given the complexity, in this audit we didn't ask what the variations would be. I think it's safe to say there are significant differences between the manufacturing sector and electrical utilities. The variation is within the emissions profiles per industrial sector and then certainly at the installation level. One of the observations we make is that this is a complex system and it's a complex problem.
