Depends what sort of pollution though - obviously if you're talking GHG emissions or many other small-molecule airborne pollutants (though not CO) it doesn't really matter where it's being emitted. But other sorts of pollution are much more local, and depending on the surrounding ecosystem (esp. waterways) and level of human habitation, it very much may well make sense to ensure it only occurs in areas where it will have less harmful effect.

Agree with your comments but ghg are not pollutants. They are a necessary part of an ecosystem that is being tipped too far in one direction

Sounds a bit like the claim that micronutrients like zinc or cadmium can't qualify as toxins (despite having toxic qualities at high doses).
