"If air travel accounts for less emissions than passenger cars..." I presume you're talking absolutes, but ICE cars (particularly the more fuel efficient ones in Europe) produce less CO2 emissions per passenger mile that planes as far as I understand it, particularly cars with multiple occupancy. I live with my Spanish wife in the UK, and our family goes to see her parents in northern Spain once a year. Having done the calculations it's way better for the three of us to drive than fly. I also don't agree with the idea that you need to fix one thing before the others - why not try to fix all of them? I don't think it's beyond our ability to tackle more than one thing at a time. The issue here is that emissions from air travel are accelerating - if we do nothing now that will just get worse.
