The answer to the honourable member's question is as follows:

The Climate Change Policy Unit within Industry Environment and Defence Division (IEDD) of Treasury had 13 people involved in the development of the Clean Energy Future Package.

Other areas of IEDD and the Department that were involved in the development of the package include Macroeconomic Modelling Division, Social Policy Division, Indirect Tax Division, Infrastructure Competition and Consumer Division, Personal Retirement Income Division and Tax Analysis Division. These divisions have broader responsibilities but around 87 people had some level of involvement in developing the package.
