there would have been an increase of 41 per cent in greenhouse gas emissions and even if everybody met their target under Kyoto—which, manifestly and in most cases, unlike Australia, they are not going to—the greenhouse gas emissions would have risen by 40 per cent. So we would have purchased for the entirety of Kyoto but one per cent. The other reason is the reason that I gave in the answer to my first question, and that is that Kyoto in its present form—and there is no likelihood of it changing—does not obligate countries like India and China and does not include the United States. If you add those three countries together, you have approximately half of all of the greenhouse gas emissions.
