The Red Meat Industry Forum describes processing beef carcasses in a doument (BeefCarcassRMIF.pdf) found here.
The parts of cattle, pigs and sheep not required for human consumption are collected by licenced renderers, usually on the same day.
Renders process most animal by-products from the meat production chain that do not end up on the consumer’s plate. In the western word, this represents about a third of the weight of animals slaughtered.
It is a complex issue to allocate carbon footprints to items that are the co-products of a beef carcass – dividing the overall footprint into the separate footprints of sirloin, rump, brisket or bone. But if the waste from a carcass is discounted, the remaining beef has a carbon footprint 37 times its own weight, under the assumptions of the previous post.
The Green Ration Book says
The average UK citizen creates 11 tonnes of Carbon Dioxide ( CO2e) a year. New UK targets aim to cut this by 80%. Dividing the ration equally between categories “consumables”, “building”, “transport” and “government”, allows 1.5kg per day. - The Green Ration Book
Food will be probably be a large proportion of a consumables ration, say 1kg CO2e, or 2.2 pounds. If beef steak has a carbon footprint 37 times its own weight, a whole days food-carbon ration would be less than 28gm of beef steak.
That’s a whole day’s food-carbon ration spent on an ounce of beef.
