I understand that. But according to your own report, you say that all they were prepared to buy was 20% in terms of domestic credits. You have an 80% shortfall. It can't be domestic. It obviously has to be international, which then gets into other countries. Your own report says you're not at all impressed with the eastern Europe scenario because it's not sustainable. That's what I understand from chapter 1 of your report.
To rephrase the question, if that's the only other option and it's not sustainable over there, why did the previous government demonstrate that they had seriously considered other models? If we're not using the eastern Europe one, were any other models looked at, as in the U.S. and the sulphur trading there? Was anything else looked at?
