    Environmental performance of pig supply chains: Guidelines for assessment (Version 1)
    Livestock Environmental Assessment and Performance Partnership
    2018
    Also available in:
    No results found.

    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.

    Measuring and modelling soil carbon stocks and stock changes in livestock production systems - Guidelines for assessment. Version 1 2019
    Also available in:
    No results found.

    These 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 the livestock supply chains through better methods, metrics and data. These guidelines provide a harmonized, international approach for estimating soil organic carbon (SOC) stock and stock changes in livestock production systems. The intended uses of this document are all those having an interest in quantifying soil carbon stocks or stock changes. Wide is the range of objectives and scales for SOC stock change studies, for example: Global or regional accounting for GHG emissions and removals from the land sector as a component of climate change accounting; Monitoring, reporting and verification obligations for the United Nations Framework Convention on Climate Change; Analysis of the climate change impact of livestock products; Evaluation of the environmental impacts of grazing land management for animal agriculture; Assessment of the mitigation potential of agricultural practices at an industry, region or farm scale; Implementing mitigation options in an emissions trading or other market mechanism where payments for SOC sequestration depend on accurate and verifiable quantification; Research into soil and biological processes affecting SOC stocks and dynamics. A set of methods and approaches are recommended for use by individual farmers or land managers, by those undertaking life cycle assessment of livestock products, policy makers, or regulators at local, regional or national scales.

    Environmental performance of feed additives in livestock supply chains. Guidelines for assessment
    Version 1
    2020
    Also available in:
    No results found.

    The production and the use of feed additives influence the environmental impact of livestock production. The use of feed additives significantly acts on feed efficiency, and thus animal and environmental performance. The methodology developed in these guidelines aims to introduce a harmonized international approach to the assessment of the environmental performance of feed additives in livestock supply chains taking into consideration the impact of their production and use all along the supply chain for large ruminants, pigs and poultry. The objective of this technical document is twofold: on the one hand, to provide detailed guidance on how to measure the environmental performance of the production of feed additives, and on the other hand, how to measure the effects of feed additives on the environmental performance of livestock products. The guidelines on the environmental performance of feed additives in livestock supply chains are intended to be used with other published LEAP guidelines.
