Carbon emissions from food production may go down about that much. However, those emissions are only about 30% of the total CO2 emissions humans are responsible for, if I recall correctly. So, total CO2 reduction would be about 18%.
and likely other un predictable knock on effects would reduce the benefit, like going vegan would mean more food is available overall, and population might rise in response.
Maybe. Due to not just the caloric availability, but due to eating habits that may influence behavior.
