This sounds like "Great White Father" stuff to me. Are wealthy countries really so suited to telling poorer ones what they may and may not do to join the wealthy?
Yes. It's imperfect but that's the way it is, it's already in place with 'Nuclear Non Proliferation' [1] and many other things. It's a 'free world' until interests are threatened, then you see where the balance of power is, moreover, there are legitimate issues of responsibility here. Canada, Japan, Ukraine, Brazil, Cameroon - all different places in so many ways, it is what it is. That's diversity.
EDIT: FYI I'm being a bit tounge-in-cheek with the garbage thing, I realize 'Rich Countries' don't do sewage and garbage perfectly well either, which is partly the point. The other point is that other places are objectively much worse.
