Yes, challenging the increased or more protective standards would be inconsistent. Those kinds of provisions, I think, are good. Even in the NAFTA we had the commission for environmental cooperation, which does some very good things. For example, it compares the national emissions by the biggest polluters across the three countries. Those kinds of extra provisions are helpful.
I will be quite interested, as more and more of these agreements are negotiated, to see how much the parties—the states—actually give them living force, in terms of paying attention to how much they are improving and increasing the protective level of their environmental protection. Language is useful. It's somewhat vague, but it's useful, especially if the parties actually pursue that line of inquiry to say, “Well, what have you done lately to increase your environmental protection? Can you demonstrate that?”
