Thank you very much for the question.
Indeed, as I tried to make reference in my remarks, I think that's an important area for us to be pursuing with the United States. We have the credentials, and granted, they're going to get even better in terms of the industry's performance over the long run.
I suggest that we don't want to make perfection the enemy of the good. I think we can start with some interim steps to start documenting, as you say, that performance.
In the steel industry, we happen to have international benchmarks now, which are starting to show some of that....
Obviously, ideally over the long run, we'd go to life-cycle carbon analysis—the full footprint—but I don't know that we need to have all of that in place before we get started.
I think you raised a very important point. This is an aspect we need to move forward on, and I don't think we want to wait until we have spent 10 years perfecting the life-cycle analysis approach.
