Maybe this is something we'll explore over the course of the meetings in a review of this bill. My concern would be that maybe there is a test that people are using to determine whether it's more or less carbon-advantageous, but when people are making that decision, they're not making it under the threat of future litigation in the tendering process. Once you add this extra layer of enforceability directly within the act, I wonder whether the types of measures that are being used would survive scrutiny, whether we'll end up with umpteen court cases about what measure of carbon we should use, whether we have to count the full life-cycle cost of the carbon footprint of extracting the limestone out of the ground for the concrete. It all gets very complicated. It's okay to say you have a tool that's useful as a guide. It's different from having a tool that's useful as a guide, to go to a tool that's going to stand up to legislative scrutiny in the tendering process. In Canada there's already too much litigation on tendering.
What are your thoughts on that?
