1) The LEAP partnership is a multi-stakeholder initiative hosted by the FAO that aims to build consensus on comprehensive guidance for assessing the environmental performance of livestock supply chains. 2) LEAP has developed reference tools through technical advisory groups and published 6 technical guidance documents in its first phase (LEAP 1) covering feed crops, poultry, small ruminants, and other topics. 3) The current phase (LEAP+) is supporting application of LEAP guidelines through road testing, while also broadening the scope to cover additional environmental topics like nutrient flows, water use, soil carbon, and biodiversity through new technical advisory groups.
