I'm not going to delve into previous commentary by anyone, but I would say that as we have discussions with the United States and with other members of the international community, everyone is working towards an architecture of a system that reduces greenhouse gases while simultaneously ensuring that we have the energy sources to fuel our society. There is no doubt about that.
In the context of North America, that needs to take into account the very extensive hydro resources that we will produce as a country. It needs to reflect smart use of renewables. It needs to reflect the reality of the hydrocarbons that we consume in North America, across the border.
You asked the question of whether there will be credits. None of this, at this point, has been agreed upon. Obviously, you start from common targets and common principles and then delve into what the architecture of a system might look like.
What has been proposed to this point in the United States is a system of cap and trade, whereby all carbon emissions in American society will be capped, there will be a 100% auction of those allowances, and they will then be traded in the American marketplace.
