(A) Non-CO2 GHG emissions from global ruminant livestock (cattle, sheep, and goats) by production system and region. (B) Spatial distribution of non-CO2 greenhouse emissions from ruminants (kg CO2 eq kilogram edible animal protein). The relationship between the diet quality of ruminants [ME (MJ)/kg DM] and the non CO2 greenhouse gas emission intensity for edible animal protein (kg CO2 eq per kilogram edible animal protein) from ruminant milk (C) and meat (D).
