I would really like to have fine-grained information on the distribution of emissions in a society. Nobody in my circles is flying more than at most once per year but I know someone who's flying bi-weekly over transatlantic distances (to either the US or to Asia). They certainly contribute a good deal to the average emissions that we do not.
