Livestock development and climate change outcomes can support each other. More productive and e cient farm systems generally produce food at much lower greenhouse gas (GHG) emissions per unit of product. However, many countries use simple (Tier 1) methods for estimating livestock emissions in their GHG inventories. Tier 1 methods are unable to capture the reductions in emissions intensity that result from improvements to livestock farming. This booklet shows how advanced (Tier 2) inventory methods can support climate change and productivity goals and help broaden countries’ policy options.
