Senator Cormann asked the Minister representing the Treasurer, upon notice, on 18 August 2011: With reference to the Treasury Carbon Tax modelling, Strong growth, low pollution: Modelling a carbon price, and specifically Table 3.5 (Global headline indicators) on p. 40 of the Treasury modelling: (1) Why does the level of actual emissions in 2010 differ across the 3 scenarios. (2) Is it correct to infer from the data in this table and elsewhere that the Treasury modelling envisages a real AUD/USD exchange rate of around $1.07 in 2010, rising to around $1.14 in 2020 and then dropping back to around 76c by 2050.
