[QUOTE="russ_watters, post: 6832597, member: 142"] I agree, lifecycle emissions include manufacturing/servicing, but with a really, really big caveat: most of those indirect (not from the fuel) lifecycle emissions are pass-through from other sectors; energy and transportation. So if you fix those sectors, the indirect emissions go way, way down. And while I too would like to see the numbers, since a rocket by empty mass is mostly a flying fuel tank I would find it hard to believe manufacturing carbon emissions is a significant fraction like it is for a car. Cars are even unusual amongst vehicles in that they have a very low utilization rate, which makes the manufacturing emissions a larger fraction than other vehicle types. [/QUOTE]
