Thanks for explaining your thinking.

> It’s very hard to calculate exactly how much the ecosystem inside a country borders can offset, but a good enough metric is its landmass.

I think this is a flawed basis, because weather patterns, sea rise, etc. don't honor country borders. Only highly localized pollution is somewhat "constrained", but country borders are even porous to that.

So I still don't know that it is an effective incentive to find a better balance. Per capita also has its problems, like penalizing less-developed countries from developing their societies, industries.
