The only costs that I know of that are not included into the price of fuel is the subsidies that are paid to oil companies. An enormous unrelated cost at the pump is taxes, much of which is used to maintain roads. Taxation will need to change as electrics and hybrids become the norm and gov't revenue declines.
I see a vague connection between outsourcing and this topic, but the problem isn't outsourcing itself, as the alternative is extremely inefficient. The real problem discussed in the OP is pollution caused by shipping products. It seems the solution then would be to develop shipping vessels that pollute less while not costing more money.
Ultimately alternatives will arrive due to the increasing scarcity of petroleum and the inevitable price increases.
