Mr TRUSS (Wide Bay—Leader of The Nationals) (14:08): My question is to the Minister for Employment and Workplace Relations. I refer the minister to his statement yesterday with respect to Treasury modelling showing aluminium production will more than halve by 2050 under the carbon tax. I quote his statement: First of all it's how you use the modelling and that depends upon the rest of the world doing nothing. As the document actually states 'The modelling assumes comparable carbon pricing in other major economies from 2015-16', does the minister stand by his statement? Honourable members interjecting— The SPEAKER: When the House becomes silent I will call the Minister for Employment and Workplace Relations to answer the question. The House now being silent, he has the call.
