If it means a meat meal represents 4x the emissions of a vegan meal, then yes that seems low.
If it means a meat eating person’s emissions are 4x a vegan person’s, that’s different. It means meat is 75% of the average person’s emissions. That doesn’t seem low to me.
It's about the total environmental impact of their diet, and the 4x figure is comparing vegans to high-meat diets (>100g/day on average)
Only four? I thought it'd be much higher
