I was thinking about P and what it could be, I doubt it is a person, more likely an organization. Anyway so I found an organization called PARIS21, I have only just started looking into it but I wanted to see if anyone had heard of it before? I see Bill Gates Foundation has donated.

"PARIS21 was established by the United Nations, the European Commission, the Organization for Economic Co-operation and Development, the International Monetary Fund and the World Bank."

I will keep looking into it anyway but I thought it looked interesting.
