Thank you, Mr. Chairman. I just want to pick up on one question before I go to the area I would like to explore. But one of the questions I think in my mind -- maybe it wasn't 100 percent clear, and perhaps it's -- I'll frame it this way: Is the department exploring options for a replacement carbon tax? Have they come up with scenarios or any type of framework if things change? Because I can't imagine the government sitting in complete absence of this in their mind and completely sitting on their hands while this is a live issue? So this is not more hypothetical. This is the fact that are they exploring options or in scenarios? Thank you.
