I think the answer to your question is yes. I can provide information to the committee. I didn't bring it with me this time.
For the chemical industry, I provided information when I talked about our reducing emissions report last May, where I discussed in detail what we're doing on climate change. We also track what we've been doing on emissions of substances like dioxins and furans, and those have been substantially reduced.
I know it's also the case in broader studies that have shown it outside the chemical industry. The government folks might want to comment on that.
I don't think it means we need to stop in that process. I think it's a continuing process. The goal in Stockholm and the goal in VE say you keep going and you keep trying to get lower. We would agree with that.
More needs to be done, but it is from a basis of a lot of progress already having been made. These are the worst of the worst substances, and there is no discussion or argument about that. We know we need to do whatever we can to reduce it.
