>Yes, it'd be nice if oil refineries were run tightly enough that they had no local emissions, but those refined products are all going into the fuel tanks of jet planes, ships, trucks, power plants and personal vehicles, from whene they will be combusted to CO2 and injected into the atmosphere, so does it really matter where the emissions take place If you can avoid waste at the refineries and the fields, less fossil fuels will have to be dig up to fulfill the same demand. Of course waste is an important issue to tackle. Sure, lowering demand or restricting supply may do more, but waste is often a relatively easy thing to tackle.
