Is regulation the word you're looking for? It seems like you just need to get pricing right not regulation.

Yes, the word I'm looking for is "regulation".

Environmental pricing doesn't make much sense now, does it?

Another word I'm looking for is externality, as in: negative externality.

Actually, I'm not looking for words at all. I know these words well, and use them with intent.

Do you?
