Component 2

Global database of GHG emissions related to feed crops

Emissions attributed to feed production are needed to compute any LCA of livestock food chains. There is however no global dataset available to the practioner and available data is generally of limited geographical relevance and does generally not account for changes in carbon stocks related to land use and land use change.

This component will focus on the development of a global database of GHG life cycle inventory (LCI) data for major feed crop materials. The assessment will encompass the life cycle emissions related to each feed component with a particular focus on improving the methodologies for quantifying changes to C stocks associated with land use and land use change.

Expected outputs

  • Database of default values for GHG emissions associated with the production of feed crops by crop type, location of production and cropping systems.
  • Documentation of methods and key assumptions.
  • Protocols for the maintenance and development of models and databases.
