We do use a shadow carbon price to evaluate risk over the long term, so as we look at our plans for growth and new projects and want to ensure that we're evaluating all of the risks. We stress test them by using a shadow carbon price. In our public disclosure, you will see that we use about $60 or $65 as a shadow price.
However, that doesn't mean that we're proponents of a $60 price. It's about stress testing and risk testing our projects.
