From a theoretical standpoint you can argue that the "fair" price of fuel would include the costs of any environmental and economical damage done by burning that fuel: the cost of health issues from particulates, the infrastructure costs to deal with sea level rise, the costs from droughts that are worse because of increased CO2 in the atmosphere, etc. Just because those happen to somebody else than the person burning the fuel doesn't mean that the costs don't happen.

And the best way we currently have to price in those externalities is artificially rising the price of the offending product, to give alternatives a better chance to compete.
