How much does air travel contribute to someone's "carbon footprint"?
>inb4 anthropogenic global warming isn't real
irrelevant, I just want to know do my friends and family to fly to America and Asia (I'm European) contribute a lot more than me? Would air travel and international holidays be the major lifestyle variable that increases someone's "co2 footprint"? because I don't do that and I'd like to know if that means I'm more morally virtuous than these libtards who fly to America twice a year
