Nothing you do matters and it all pales in comparison with what India and China are doing. The industry is moving forward, and if less co2 is something it cares about, changes will be made over time (it's happening now). Flying less doesn't do anything, other than deprive the industry of funds needed to make the transition.
There is a lot to be said about the ethics of elites doing any given thing, while telling you to live in a cage, eat bugs, and not do anything interesting with your life, while themselves doing the opposite and quietly promoting the opposite.
