Livestock Activity Data Guidance (L-ADG) - methods and guidance on compilation of activity data for Tier 2 livestock GHG inventories (Paperback)

The purpose of the Livestock Activity Data Guidance (L-ADG) is to improve the accuracy of livestock emission estimates in national greenhouse gas (GHG) inventories, and enable countries to measure and report progress towards their Nationally Determined Contributions (NDCs). Livestock emissions - including enteric fermentation, manure management and emissions from dung and urine deposited on pasture - account for about 11 percent of global GHG emissions.A recent review found that among 140 developing countries, 92 have included livestock-related emissions in their NDCs. However, very few have national GHG inventories that are able to track changes in livestock emissions resulting from mitigation policies and measures, which requires a Tier 2 approach as defined by the Intergovernmental Panel on Climate Change (IPCC). This occurs because a lack of activity data and incomplete or poor-quality data hamper the use of the Tier 2 approach.The L-ADG focuses on estimating activity data from the main ruminant types found in developing countries - cattle, sheep and goats - and provides guidance on how to: identify and assess the availability and quality of existing activity data; structure a Tier 2 inventory to make use of available data; compile activity data when data exists but is incomplete or of insufficient quality; estimate activity data when data is missing; and assess the quality of data and identify priorities for continuous improvement..
