I'm afraid I'm really not enough of an expert to answer that. I'm not close enough to the negotiation. I do know that we want to have a sort of key that would be based on capacity to pay and also the cost of mitigation, which would be different for different countries. For some countries there will be quite easy opportunities to mitigate, and for others it will be more expensive. Whatever key we have needs to take account of that and also take account of those who've already taken early domestic action and those who haven't. That also needs to be included in the calculation--and population trends.
