We focus on ruminant livestock since it has the highest emissions intensity across food sectors... While shifting consumption patterns in wealthy countries from imported to domestic livestock products reduces GHG emissions associated with international trade and transport activity, we find that these transport emissions reductions are swamped by changes in global emissions due to differences in GHG emissions intensities of production.

Research comparing ruminant livestock production systems also shows that organic farming systems perform favourably, in terms of energy use, due to energy savings associated with reliance on clover - grass leys and high forage / low cereal diets (Lamp - kin, 2007). (chimalaya.org)
