The pork and poultry v lamb and beef thing is interesting - on the one hand, sheep and cows are ruminants so they produce more greenhouse gases by way of methane, and pigs convert plant matter to protein more efficiently, but on the other, pigs and poultry need cereal feed whereas cows and sheep can be reared on grass alone. I tried to find a similar graph for UK produced food but haven't managed it yet.

In the US, 'grass-fed beef' is something special; ordinary beef is fed in feedlots on grain.
