I think anything that is sector-specific is a bit troubling. You didn't ask about this particularly, but it came up earlier that we have very large subsidies for certain types of investment in energy, so you're effectively picking winners. Since every dollar has to come from somewhere, I am concerned about that.
If we went to a pure carbon-pricing system and used the output-based measures to limit the impact on our competitiveness, I think that would be good.
