This was my conclusion too while using one of those calculators. One year of eating "normal" amounts of meat instead of being a vegetarian has about as much CO2 equivalent impact as one flight across the Atlantic Ocean. I'm still trying to reduce meat consumption (and choose e.g. chicken over beef) but going on holiday e.g. via train instead of by plane is way more ecologically impactful than becoming 100% vegan...
