We have to make sure that our targets are achievable, for starters, and it's one step at a time. I made reference to the Canadian renewable fuel standard earlier. It was a good departure point. The reason it was a good departure point is that they took a lot of time, through Natural Resources Canada, to study the issue, to understand what was possible and what could be blended into the fuel mix, to learn how it was going to be produced, to see where it would come from and to see what the long-term GHG implications of that would be. That is work that is under way right now, and it's under way in many different parts of the world.
I think what I would tell this committee is that every part of the materials ecosystem can be improved. Therefore, we start working on the things we have in front of us, and when we have a recycled content mandate, you will see people who take long-lead financial decisions to upgrade their operations, but it has to be in law.
