Again, a naive question: how do you know that 27 entities will come to an agreement on individual targets? That's one question.
The other question is, will there be cross-subsidization from one country to another? For example, if there's a country that's weaker or less able to achieve an ambitious target, would there be some kind of fiscal cross-border assistance from one country to another?
In Canada, when we talk about reaching the 2020 target of a 25% reduction below 1990 levels, there's always the caveat that there would have to be redistribution of income. For example, a certain percentage of moneys raised from the oil sands would remain in Alberta. So you'd have subsidies to one part of the country that wouldn't apply across the country in order to achieve this idea of keeping a certain amount of money in a certain region. Is that the kind of model you'll be dealing with, or is just going to be emissions credit trading and that's it?
