First of all, I think we should stop using the word “voluntary”, because it has the wrong connotation. It has the connotation that these are things you do if you want to. Where you're going to have these kinds of programs and you're going to rely on industry to do it in a non-regulatory sense, I think there should be some ability to count on industry to be able to deliver.
There should be infrastructure with the sector reporting. It's not voluntary in the sense of “do it or not do it, it's up to you”. It's that the legislature is going to take a route of having industry use a non-regulatory approach, with the assurance that it will get done. So that's why I call these things industry responsibility programs instead of voluntary programs.
It's a nuance perhaps in language, but I really wish that 10 years ago when we started to talk about these we'd picked a different word. I think we trapped ourselves collectively into the wrong lexicon on this.
I think industry responsibility programs need to be more embedded in the act in trying to make sure they actually do deliver on what's committed. That's why I suggested that one approach might be tying them to pollution prevention planning, which gives the use of a quasi-regulatory instrument. The government can set out factors to be considered, things that it would like done, and the industry can respond through its industry responsibility program of how it's doing that.
As I said, I think that's allowed for in the act; the problem is that there seems to be not much political will to use it. And I think that's partly because of this false dichotomy we've set up of voluntary, which has the notion in the public that they can do it if they want, versus regulatory. I think there's really this very important ground in between where you're not using a regulation, which tends to be complex and with which I think it's much more difficult to achieve results, but you are using the fact that it will happen, it will get delivered, and you're tracking against that.
I hope that helps.
