For food consumption figures is uses 2007 data from Defra's Family Food Survey (which provides data on food purchases).

The FAO has published a life cycle assessment of the global dairy sector. The assessment is part of an ongoing research programme to assess the environmental implications of animal food chains, and to analyse and recommend improvement options.

The LCA takes into account the following: From cradle to farm gate
