Colleagues at the table may want to add something as well.
I think you're referring to beyond just pricing pollution. You're referring to the broader efforts and regulations that will aim to phase out coal by 2030.
To speak to it from the carbon pollution pricing side, yes, there is economic analysis under way. In terms of the analysis that my team and I are part of, we're looking at the impact of a price on pollution on those sectors and at some of the economic and competitiveness impacts. That analysis is still ongoing. There are three phases to it. It cuts across all the major industrial sectors. In particular, we're looking at it in the context of developing the output-based pricing regulations. It includes cement.
