Its a shared atmosphere, so they will suffer the effects of it equally. This isn't a "just the US" type of thing. if you suffer from hurricanes or monsoons, earthquakes, and so on, it is in your best interest to reduce the effects of pollution.

We also haven't agreed to punitive actions, tax credits incentivize cleaning, but there is barely any punishment or accounting of it. Else coal which is probably the worst form of energy production would not exist.
