I completely agree with that. We view environmental performance and environmental responsibility as a key competitive advantage. It's one of the reasons for a $2 billion spend on an environmental project.
We report out against the Global Reporting Initiative—a GRI index specifically designed to report apples-to-apples comparisons on environmental performance against major industry players. Investment firms are making investment decisions based on our performance on the GRI index, so there is no question in my mind about that. Environmental responsibility is a competitive advantage, and in this day and age, as we're developing the next generation of miners, it is critically important to recruitment and retention.
