"A global assessment of livestock mitigation from reducing emissions and enhancing soil carbon stocks"
by Henderson, Benjamin, Alla Golub, Daniel Djauhari Pambudi, Thomas Hertel and Pierre Gerber

In this study the standard GTAP livestock commodity aggregation scheme is modified to provide both more disaggregated and practical representation of the livestock sector in the context of greenhouse gas (GHG) mitigation. The most significant of these modifications is the re-specification of the dairy sector from a single commodity (milk) industry to a multiproduct dairy sector that also produces significant quantities of meat from culled and fattened animals emanating from the total dairy herd. The GHG emission intensity of meat from the dairy herd is significantly lower than meat from specialist beef herds. Accounting for these differences allows us to better understand the potential impacts of emission price policies on livestock sectors. The ruminant sector is split into small ruminant and large ruminant sectors and the non-ruminant sector is split into pig and poultry sectors. The application of a 27 $/tCO2eq global GHG emissions tax to the livestock sector was shown to abate 628 MtCO2eq or 20% of the sector’s total emissions (not including soil carbon sequestration). Of particular interest are the vastly different market adjustments in the highly substitutable meat products from dairy and large ruminant sectors in the wake of the emission tax, resulting in a substitution away from of large ruminant meat towards the production and consumption of less emission intensive dairy meat. The disaggregated pig and poultry sectors also provided new insights. The poultry sector, despite lower emission intensities than the pig sector, suffers a substantially larger contraction , due to having relatively limited abatement potential. Finally, the inclusion of soil carbon sequestration as a mitigation option in grazing lands was shown to increase annual livestock abatement by 235 MtCO2eq (37%), demonstrating the importance of considering option.
