the company doesn't need to understand good or bad, just profit. so, regulate them. disincentivise the negative externalities of greenhouse gas pollution through a carbon tax. then the next question would be "how do we get our government to install a carbon tax? (and not revoke it after a few years)" and "how do we negotiate trade deals with other governments that haven't signed up to a similar carbon tax, to pressure them to establish one as well?"
