Okay, that's helpful.
When we're talking about national standards, I know there are different numbers. We could also help to define what those are. They have to be 1, 2, 5 or 7 to be able to be recycled, so we could also establish that at the national level. I'm just throwing those out there. Thank you.
One of the other things that had come up is around measurement, how we start measuring progress and how we measure, I think, different parts of progress. Would there be any recommendations or thoughts around the type of data that would be useful for us to start gathering, so that we can actually start making some progress around reducing plastics pollution?
