In our negotiations, which are going on right now and are at a very critical part right now, the focus is the commitments that countries are going to be taking on after 2012. Canada, in defining what its commitment should be after 2012, can make some calculations based on investments that it's making now on carbon capture, on clean coal, on east-west, and make calculations that these will result in these kinds of reductions and that it will put us on this kind of emissions path.
Out of that scenario, we will use so many megatonnes, at an interest rate that the Kyoto Protocol obliges, to compensate for the fact that we didn't meet the specific allocation defined under the Kyoto Protocol between 2008 to 2012. That is the mechanism by which Canada could do it.
