Sure. I do really want to echo the same perspective from the agriculture sector here. We have a lot of best-in-world technology already, so it will be very challenging to have the emission reduction targets. It's not that there is not more we can do—we can look at that—but we think it has to be a consideration. When you're already the best in the world at something in terms of energy efficiency, it's pretty difficult to get any lower than that, particularly when you have other countries that do not have emissions targets, will not have a carbon tax, and we're increasing our input costs and can't control the price we've getting at the end of the day. So this has to be thought through.
We're being challenged by a lot of potash development in Russia. They don't have these same input costs and they're already telling us that they can produce at half our cost per tonne, so any increase in costs that is not transferrable is difficult for us, and the carbon leakage that you hear about is very real.
Thank you.
