Hon JAMES SHAW: Yes. Those two things are kind of countervailing forces, and both of them have significant sets of implications, some of which I've canvassed quite a lot already. So we do have a work programme. It is some regret to me that once we have passed this bill, it will not be the final chapter of the emissions trading scheme, that there is therefore further work to be done. And we will come back again, possibly with a future amendment based on exploration of those two sets of factors.
