The environmental impacts are calculated with the methodology of Life Cycle Assessment (LCA).

• Functional unit: 1 kg ;
• Time period: 2008 – 2012
• Scope: different scopes are proposed depending on the needs and the ingredients
  • from craddle to field gate
  • from craddle to storage agency
  • from craddle to French port
  • from craddle to mill gate
• The calculated impacts follow the ILCD recommendations and the usual practices of international scientific references (CML methodology).
  • Phosphore consumptions (kg P)
  • CED 1.8 non renewable fossil+nuclear (MJ)
  • CED1.8 total (MJ)
  • Climate change ILCD (kg CO2 eq)
  • Acidification ILCD (molc H+ eq)
  • Terrestrial eutrophication ILCD (molc N eq)
  • Freshwater eutrophication ILCD (kg P eq)
  • Marine eutrophication ILCD (kg N eq)
  • Acidification CML baseline (kg SO2 eq)
  • Eutrophication CML baseline (kg PO4---eq)
  • Land competition CML non baseline (m2a)
  • Global warming (GWP100a) (kg CO2 eq)
  • Climate change without land transformation (kg CO2 eq)
• The methodology for LCI follows the guideline of Agribalyse with some updates :
  • The LCA methodology is homogeneous among inputs,
  • The emissions models were selected to be adapted to French context.
• The Foreground data of LCI were based on statistical data, network of farms (case study), bibliography and expertise.

The database contains 60 ingredients and 150 LCA. It allows:

• To represent the current formulation of animal feed.
• To simulate innovative formulations with the use of emerging inputs
• To use data of cereals at farm gate (for the production of feed at farm) or at the exit of storage agency (for feed manufacturer).
• To have data at the exit of mill for transformed inputs (case of meals).
• To have different transformation process.
