My second question is over to you, Mr. Vaughan.
I'm dealing specifically with the $1.517 billion climate change and clean air trust fund. At the time that was announced, the statement was made that this would result in a reduction of 16 million tonnes of greenhouse gases on an annual basis. Given that there's no mechanism for any kind of accountability, would you agree with me that this is just someone's wild guess and there's absolutely no factual basis for that statement?
