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:

Given that ‘Chart 3.5 of international carbon prices’ shows prices for the European Union emission trading scheme (EU ETS) only on a ‘3 month moving average’ basis, and only from 2008 onwards.

(1) Why does Chart 3.5 only go back to 2008, instead of to 2005 when the EU ETS started.

(2) How much more volatile would Chart 3.5 look if it were plotted on a daily

or weekly basis.

(3) How many days have there been during 2011 to date when EU permit prices have fallen or risen by:

  (a) 10 per cent or more in a day;

  (b) 5 per cent or more in a day; and

  (c) 2 per cent or more in a day.

(4) How many weeks have there been during 2011 to date when EU permit prices have fallen or risen by:

  (a) 20 per cent or more over the course of a week;

  (b) 10 per cent or more over the course of a week; and

  (c) 5 per cent or more over the course of a week.

(5) What are the lowest and highest nominal permit prices recorded in the EU ETS since its inception in 2005, and what is the current permit price.
