I think it's more the content that matters rather than where they're placed. As a matter of fact, when the agreements were brought into the trade agreements, the scope of the obligations was narrowed. When they were inside agreements, there was an obligation to seek to have high standards generally, but when you bring it into the trade agreements, you're talking about a failure not to enforce your environmental laws and so on as they affect trade. In fact, it's put in a trade perspective and is less broad than it would have been otherwise.
The thing about the agreements of the environmental provisions, which are found in chapters now, is that they are getting broader and more substantive. I think the more important question is whether we need dispute resolution on them to make parties take them more seriously. That's where I would see future work on the environmental chapters. Plus, we could have innovative provisions added that deal with co-operation on clean tech and that deal with increasing trade in environmental goods and services. There's more work that could be done there, and I think it would be worthwhile, although I think where it is matters less.
