asked the Minister representing the Treasurer, upon notice, on 18 August 2011:

With reference to the Treasury 2008 Carbon Tax modelling Australia's low pollution Future, is it correct that in the Carbon Pollution Reduction Scheme (CPRS) modelling no global borrowing of emissions from the future occurred in the CPRS-5 scenario at any stage prior to 2050.

The Treasurer has provided the following answer to the honourable senator's question:

Chart 5.3 in Australia's Low Pollution Future report (page 96) shows that the implied level of globally banked permits in the CPRS -5 scenario remains positive in 2050.
