Though I’ve taken various measures to reduce my CO2 emissions (being vegan and car-less, etc.) I have realized that the effect of all of these choices is negligible if I fly multiple times a year. Since my family lives abroad I will never reduce my flying to zero, but at least for work I have alternatives. I have just started my journey of flying less so I do not have many ideas yet, but so far I have come up with only visiting conferences close-by that I can reach by train, and trying to combine activities abroad.
