The idea that you shouldn't do a helpful thing just because it won't entirely solve the problem all by itself nuts. Even assuming that the estimation method used here is entirely without flaw, they estimate a 6% per capita savings. That's not small! Just because there are more impactful things you could do, doesn't mean you shouldn't also do this.

Another variant of this that's no less infuriating is the classic "corporations do most of the polluting, so I'm entirely absolved of responsibility".
