I have one quick comment.
To be absolutely clear, if you look at the subsectors in the mining industry, for our iron ore pellet plants we have one plant that would be under-meeting the Kyoto target within the timeframe. We have another one that would not meet its target because of the nature of the steel product demand for an acid flux pellet, which has a higher greenhouse gas intensity. These are the most energy-efficient pellet plants in the world, and it depends on what the steel plants want.
It's why I made the point that if you draw an arbitrary line and you don't understand the continuum between iron ore and a steel plant, the fact that it makes an acid flux pellet is actually a huge benefit at the steel end in terms of greenhouse gas reductions, but it looks bigger at the iron ore side. It's why the system has to take those things into account, because if you isolate it there, you're going to penalize the plants that are already the most efficient in the world.
