We have operated very much on the principle of BATEA. You use the best available technologies economically applicable.

And then looking out over the longer term, which is part of the clean air plan, what are those breakthrough technologies? To get immense change, you need some breakthrough technologies in the way steel is made. There is participation by the government and the industry in what's called the carbon dioxide breakthrough project run by the International Iron and Steel Institute.
We are part of that as Canada and looking to that as a way to develop complete step functions in the environmental efficiency of the process.
