Hon SCOTT SIMPSON (National—Coromandel): Just sort of following on from matters generally relating to climate change, the Budget documents indicate that in the preceding financial year, a sum of over $400 million was received by the Government in terms of the emissions trading scheme (ETS) contributions that went into the consolidated fund. That was at a point when the carbon price was kept at $25 dollars, and since the changes that this Government has introduced to the ETS have been promulgated, a carbon price today, I think I had a look, was in excess of $33 a tonne. So the funding stream that will eventually find its way into the Government consolidated fund is going to grow and even more so, potentially, when the trigger point that will get the cost containment reserve triggered is likely to occur if carbon gets to $50 dollars a tonne. What I'm keen to know from the Minister is: what's his view about how that money should be invested? Should it be hypothecated, should it go into the consolidated fund, or should it be ring fenced, in his view, for other items that relate specifically to carbon emission reduction?
