In an earlier post, I wondered whether there were data on the relative carbon efficiency of agricultural production in Europe versus third countries. A recent FAO study arising from a collaborative effort by FAO and the International Dairy Federation which assesses GHG emissions from the dairy food chain throws light on this. The study uses a Life Cycle Analysis (LCA) approach, and thus includes the land use change induced by the consumption of feed (principally soybeans) in intensive dairy systems.
The results are unambiguous:
