A United Nations report titled Livestock's Long Shadow (LLS) stated that 18% of anthropogenic greenhouse gases (GHGs) are emitted from the world's livestock. According to LLS, livestock cause more anthropogenic GHG than all global transportation. Recent estimates by the United States Environmental Protection Agency (EPA, 2009) on the impacts of livestock on climate change have arrived at much different GHG estimates. EPA estimates that less than 3% of total anthropogenic GHG are associated with direct and indirect livestock emissions. Part of the difference of the global versus national predictions is due to the weight assigned to ''land-use change'' patterns related to livestock production (mainly deforestation). Furthermore, LLS attempts a life cycle assessment for global livestock production but not for transportation predictions. Our work has examined the relative contributions of livestock to climate change at different geographical and production scales.
