The evaluation of the project “Livestock Environmental Assessment and Performance (LEAP) Partnership” covered the three phases of the LEAP Partnership (2012–2021). The evaluation found that the project responded to an existing demand to advance towards a science-based benchmarking of the environmental performance of the livestock sector. The LEAP partnership was a cost-effective approach that contributed to consensus building and greater understanding of the factors influencing environmental performance by providing a neutral forum for discussion and negotiation. The evaluation provides six recommendations: i) strengthen the project’s theory of change to reflect the complexity of learning and innovation, including gender perspective; ii) strengthen the multi-stakeholder partnership governance, management and procedures; iii) strengthen collaboration with other initiatives such as the Global Agenda for Sustainable Livestock (GASL) and the Global Livestock Environmental Assessment Model (GLEAM); iv) reduce the budget uncertainty through improved long-term planning and a strengthened resource mobilization strategy; v) update and improve the dissemination strategy; and vi) develop an outreach strategy with clear goals.

This is a living document produced by the Livestock Environmental and Assessment Performance (LEAP) Partnership. The document presents a methodology and provides guidance for the assessment of the environmental performance of pig supply chains. It provides users guidance on how to apply the life cycle assessment approach to pig supply chains. Demand for livestock products is projected to grow 1.3 percent per year until 2050, driven by global population growth and increasing wealth and urbanization. This projected growth places significant pressure on the livestock sector to perform in a more sustainable way. Currently, many different methods are used to assess the environmental impacts and performance of livestock products. This causes confusion and makes it difficult to compare results and set priorities for continuing improvement. The intention of this document is to provide an overview assessment of existing studies and associated methods that have used life cycle assessment for the evaluation of pig supply chains.

The aim of the methodology developed in these guidelines is to introduce a harmonized international approach assessing nutrient flows and impact assessment for eutrophication and acidification for livestock supply chains taking the specificity of the various production systems involved into consideration. The methodology strives to increase understanding of nutrient use efficiency and associated environmental impacts and to facilitate the improvement of livestock systems’ environmental performance. The guidelines are a product of the Livestock Environmental Assessment and Performance (LEAP) Partnership, a multi-stakeholder initiative whose goal is to improve the environmental sustainability of livestock sector through better metrics and data. Nutrient use in livestock production systems increased over the last decades due to the increased demand for livestock production. This demand is mainly driven by the increase in the population growth, population income, and urbanization. Consequently, in livestock supply chains, nutrient losses into the environment have contributed to environmental burdens such as climate change, air and water pollution, degradation of soil quality, loss of biodiversity and human health issues. Therefore, there is strong interest in measuring nutrient flows to improve the environmental performance of the livestock sector. The objectives of these guidelines are: •To develop a harmonized, science-based approach resting on a consensus among the sector’s stakeholders; •To recommend a scientific, but at the same time practical, an approach that builds on existing or developing methodologies; •To promote a harmonised approach to assess nutrient flows and impact assessment, relevant for global livestock supply chains; •To identify the principal areas where ambiguity or differing views exist concerning the methodological framework. During the development process, these guidelines were submitted for technical review and public review. The purpose is to strengthen the advice provided and ensure it meets the needs of those seeking to improve nutrient use efficiency and environmental performance through sound assessment practice. This document is not intended to remain static. It will be updated and improved as the sector evolves and more stakeholders become involved in the LEAP, and as new methodological frameworks and data become available. The guidelines developed by the LEAP Partnership gain strength because they represent a multi-actor coordinated cross-sectoral and international effort to harmonize assessment approaches. Ideally, the harmonization leads to greater understanding, transparent application and communication of metrics, and, not least, real and measurable improvement in environmental performance.

Greenhouse gas emissions by the livestock sector could be cut by as much as 30 percent through the wider use of existing best practices and technologies. FAO conducted a detailed analysis of GHG emissions at multiple stages of various livestock supply chains, including the production and transport of animal feed, on-farm energy use, emissions from animal digestion and manure decay, as well as the post-slaughter transport, refrigeration and packaging of animal products. This report represents the most comprehensive estimate made to-date of livestocks contribution to global warming as well as the sectors potential to help tackle the problem. This publication is aimed at professionals in food and agriculture as well as policy makers.

The Technical Advisory Group (TAG) for Water Use Assessment, composed by 30 international experts, has developed guidelines on water footprinting for livestock supply chains. The mandate of the Water TAG was to provide recommendations to monitor the environmental performance of feed and livestock supply chains over time so that progress towards improvement targets can be measured; apply the guidelines for feed and water demand of small ruminants, poultry, large ruminants and pig supply chains; build on and go beyond the existing FAO LEAP guidelines; and pursue alignment with relevant International Organization for Standardization (ISO) standards, specifically ISO 14040, ISO 14044 (ISO, 2006b and 2006a) and ISO 14046 (ISO, 2014). The guidelines on water use assessment include the impact assessment: the assessment of the environmental performance related to water use of a livestock-related system by assessing potential environmental impacts of blue water consumption following the water scarcity footprint according to the framework provided by ISO 14046 (ISO, 2014); and the assessment of the system’s productivity of green and blue water. The guidelines are thus intended to support the optimization of use of water resources and the identification of opportunities to decrease the potential impacts of water use in livestock production. The Water TAG guidance is relevant for livestock production systems, including feed production from croplands and grasslands, and production and processing of livestock products (cradle-to-gate). It addresses all livestock production systems and livestock species considered in existing LEAP animal guidelines: poultry, pig, small ruminant and large ruminant supply chains.

RTI’s Environmental Assessment (EA) Tool enables livestock and poultry farmers to evaluate their operations for environmental challenges and identify practical ways to address those challenges. Between 2007 and 2011, the Comprehensive Livestock Environmental Assessment and Nutrient Management Planning (CLEANEAST™) Project provided confidential, no-cost EAs and nutrient management planning (NMP) assistance to more than 400 livestock and poultry operations. During 2007 and 2008, RTI, our sub-agreement partner, North Carolina State University, and subcontractor, Agri-Waste Technology, Inc., designed the EA Tool, which contains over 400 questions in 12 topical areas. We pilot tested the EA Tool at two livestock operations before full-scale application. We used the EA Tool at more than 290 livestock and poultry operations in 20 states east of the Mississippi River. In total, operators received 385 EA-related recommendations for improving on-farm, environmentally related practices. We used our results to inform both livestock and poultry sectors, as well as the US Department of Agriculture and US EPA, of nutrient management practices observed; to predict potential environmental releases from technologies and practices; to measure adoption rates of recommendations, technologies, and practices; to evaluate behavioral response to outreach; and to identify future needs for water and air quality program improvements and policy. The EA Tool remains in the public domain, and as interest grows in mitigating greenhouse gas emissions and adapting to climate variability, the EA Tool can be readily expanded to inform farmers about their emissions from manure management and guide them in obtaining carbon credits for mitigation measures.

This analysis aims to summarize the views submitted on KJWA topics 2(d) that were discussed during the SB 51 in December 2019, namely: Topic 2(d) - Nutrient use and manure management. The analysis intends to make the wide range of views submitted more easily accessible to those interested, including to Parties and observers to the UNFCCC, but also experts working on climate change more generally, as well as interested members of the public.
