Historically, we've had a target on energy efficiency of a 1% per annum improvement, in terms of energy efficiency per unit of output, and that comes through our work, historically, with the Canadian Industry Program for Energy Conservation, a government-based program that has been around for quite some time. But we have developed a reporting protocol so that we understand how those energy efficiency improvements result in reductions in both direct and indirect greenhouse gas emissions.
This is work we developed with the Pembina Institute and with the voluntary initiative the government had in place in the nineties and the early part of this decade, and we've continued on with that. We feel it will put us in a good position to meet whatever regulatory requirement the government has, at the end of the day, for both reporting and target setting, whether they be caps or other types of tools with respect to greenhouse gas emissions.
By reporting, you also create the dynamic of why is company X doing better than I am, and you want to go see how they're becoming more energy efficient than you are, thereby reducing releases. So target setting will be part of this, ultimately.
