Let me just make a couple of comments.
The first, I think, is to always keep in mind that action matters. There's a lot of work being done in industry, in our industry, to reduce carbon emissions, and the broader use of natural gas I think is an opportunity to do that.
Second, there are a variety of mechanisms by which one can implement carbon policy. You've touched on all of them. There's no strong consensus among our membership as to which of those is the best. They can all be applied. I think the issue is how they're applied. There's no ideal mechanism.
We've been working with the government to proceed with carbon management and a policy framework for the oil and gas sector. We'll continue to do that. I think it's important that we move forward with policy, but more importantly, that we move forward with action.
