CARBON TAX

The Hon. D.G.E. HOOD (15:20): As the goal of the carbon tax is to reduce global warming or to impact on the problem of global warming, can the minister estimate what she believes the introduction of the tax will lead to in reduction in global temperature?

The PRESIDENT: You are asking the minister to make an estimate on a matter that has been a federal issue, and both ministers have taken up the challenge so far. Perhaps you ought to get your colleagues in Canberra to ask those questions.
