If the non-food products (which account for about 40% of the animal) are accounted for, the food-CO2 falls by ~40% to about 51.
This doesn't seem to take into account methane production and its effect on the climate either, which would probably put cows and pigs much higher.
Right. Cattle produces a lot more than just beef. Leather, horns, bones, and hooves are additional products that come from the cow. Then there's all the animal feed and plant fertilizer that come from the less desirable parts of the cow. I wonder what the carbon footprint is when the entirety of the cow is taken into account. No part of the animal is wasted during rendering.
