This page is very inappropriate for the Simple English wikipedia. First, "product stewardship" is a jargon term that many native speakers of English don't know the meaning of. Second, the content of the article itself is far from simple:
"Product stewardship includes waste disposal measures in the distribution chain of an industrial product."
"Rather than let liability for these problems be taken up by the public sector or be haphazardly assigned one issue at a time to companies via lawsuits, many accounting reform efforts focus on achieving full cost accounting."
It's not even clear to me that an article on "product stewardship" belongs in a Simple English Wikipedia. Would someone please re-write this in a way that's worthy of Simple, or at least justify why it's even relevant? If not, I'm inclined to nominate it for deletion.
