You start with developed countries, and go from there. It's only fair. They've created the most (by far, on a per-capita basis) unpaid negative externalities over the last 200 years, so they should be the first to start paying for it.

This concept of fairness seems to go against efficiency. As far as any pollution goes, you want to reduce creation and release of new pollutants as well. The old baggage is bad enough. Adding more of it means making the situation worse.

So you need to address currently polluting countries as well, because they are very much an important part of the problem. This set partly overlaps with the set of developed countries, partly not.

Happily this concern largely moot because most emissions are either directly by developed countries or paid for by them in the form of export goods from other countries.

It's only a real concern if you are very insistant about calling China and India "developing" countries.
