Do you drive an electric car and charge it on solar or wind? Or an ICE car and run it on alcohol?

Personal transport is about the same as red meat emissions-wise. Red meat is getting better though, because farm animals are in the control of farmers (unlike wild animals that might replace them) the farmers can try different things to reduce the cow's emissions. So far they have had success, with fairly light public pressure the good practices will spread.

Now replace the cows with wild deer. Try to fix their methane emissions. All ruminants make methane in their fore gut.

Incidentally I lost the most weight on a very low carb diet. Lower carb, better weight loss (and weight gain – muscle). You can go low carb as a vegan, but not very.
