Monsieur Bigras, thank you for your question.
From our point of view, the reference point is what is happening at the sectoral level between ourselves and our U.S. counterparts in terms of what the regulatory obligation will be. I think their system is clearly moving in the cap-and-trade direction. I would add that they, of course, have also introduced other measures to deal with the external trade issues, and that aspect also certainly needs to be tracked for its impact on us as producers. That's the comparability that, frankly, is important to us. It's that alignment, so that we're facing essentially the same challenge.
