Earlier quoted context omitted.
It seems odd to treat the suggestion that unnecessary emails cause excessive carbon emisions and the suggestion that unnecessary air travel causes excessive carbon emissions as the same or similar.
Do you think one has a meaningful impact? I think the implication is that on an individual level neither matters, and that suggesting, on social media, people stop traveling to prevent climate change is both ridiculous and harmful to anyone working to actually improve carbon emissions.
I have 2 small kids, life is often a daily struggle in one way or another, I couldn't care less about current carbon footprint just like I don't care about another non-urgent bottom 500 priority stuff. Vote in politicians that will take care of that instead of focusing on smooth corporate profits if you want to send positive message and change, and motivate folks to do the same to increase impact.
