Nutrient flows and associated environmental impacts in livestock supply chains
The objective of these guidelines is to provide additional recommendations to the existing LEAP guidelines on feed and livestock supply chains by including recommendations for the life cycle impact assessment of livestock supply chains, including methods for estimating and accounting for flows of N and P. Environmental impact categories are restricted to acidification and eutrophication (freshwater, marine and terrestrial). While it is recognised that N and P losses to water, soil and air play a dominant role in stratospheric ozone depletion, soil quality impoverishment, and biodiversity loss, these environmental impacts are not covered in this guidance document. Also excluded is guidance on the assessment of the impact of nitrous oxide (N2O) on ozone because of strong interactions between N2O and other greenhouse gases such as CO2 and CH4 Guidance to assess the impact of nutrients on biodiversity is covered in the LEAP principles on biodiversity.
