The report estimates that chemical CO 2 absorption would cost $35/t of CO 2, plus $8–20/t CO 2 for transportation and storage. [95] At the time, this would have increased steel production costs by 15–20%, [ 88 ] [ citation needed ] presenting a barrier to decarbonisation for steelmakers which typically operate with margins of 8–10%.

They are raised as livestock for their flesh (called beef and veal), dairy products (milk), leather and as draught animals. As of 2009–2010 it is estimated that there are 1.3–1.4 billion head of cattle in the world. [47] [48] Diagram of feedlot system. This can be contrasted with more traditional grazing systems.
