We haven't yet, actually. When we received the invitation, some of us thought that it was a little bit early, so we haven't developed a position on this. We have developed sustainable trade principles, which provide us this framework for looking at sustainable trade issues. Really, what we want is to prevent sustainability measures from becoming trade barriers.
Let me go to where work would be done. First, we haven't got to a point of saying that we think it's necessarily a good idea to do the work. We want to avoid countries having different measures that then create a lot of uncertainty in international markets.

Most agricultural trade takes place under WTO rules, so whenever you can have WTO rules, that's by far the best approach. If that's not possible, like-minded partners—sometimes groups like the G7—can be places to multilateralize preliminary solutions, ideas, and approaches. However, when things aren't decided at the WTO, almost inevitably, you're going to have patchwork rules, and that's problematic.
