Senator HILL (Minister for Defence) (7:52 PM) —I do not think that we disagree in principle with what Senator Brown is saying. He is saying that we should encourage natural refrigerants and that they have advantages over those that are greenhouse intensive. In fact, the amendments that we have before the chamber, as I understand them, have the effect of regulating the import of the synthetic greenhouse intensive products. In other words, without these amendments you have no restraint—correct me if I am wrong—and therefore you are worse off than with this legislation. So I would have thought that on that basis Senator Brown would be supporting this legislation.

Senator Brown —I am. I am saying that it falls far short of where it should be.

Senator HILL —For you, it is always far short of where it should be. But where are we tonight? We are looking at an improvement in the existing situation. Australia's record in relation to restraining ozone depletion has been commendable; we have been a world leader. As I said in my summing up, what have been substituted are products that are very greenhouse intensive. Now we would like to manage that, for a different purpose. The first one was to do with the ozone issue and the second is to deal with the greenhouse issue. In principle, we all seem to be heading in the same direction. It is just that Senator Brown would like us to head much further, but I do not know that he is suggesting the way in which that should occur.
