Only if it's downhill all the way......somewhere in the background where the energy to shift the stuff along the pipe is being generated, and that has an impact. Maybe not much compared to road tankers, but not almost nil either.
Afterthought; OK, if the fuel company generates the electricity to drive the pumps using wind or solar energy, it's almost nil. But do they?
