I think one thing is being missed here: while shorter trips are more polluting and damaging per mile (or kilometer) traveled, every long trip starts as a short trip and pollutes/wears the same until the engine warms up. Driving less is almost always a net win, even if your tank averages go down.
Admittedly there are some maintenance items associated with the engine not getting as warm, but there are probably equally many (or more) from driving a total greater distance.
