According to a paper presented to the Society of Animal Feed Technologists (UK), food production from farm to fork is responsible for up to 31 percent of EU greenhouse gas emissions and 20% of UK emissions. Livestock production is responsible for around half of these emissions. The more meat we produce and eat the bigger that carbon footprint will get. The paper states that:
“[C]rops which are suitable for human consumption are currently used to feed animals, and this is an inefficient process. A shift away from livestock based production is likely to lead to a reduction in food related greenhouse gas emissions.”
and also:
“[F]rom an environmental perspective, a reduction in livestock production can lead to important greenhouse gas reductions”
The paper also explains the primary and secondary impacts of livestock on GHG emissions, such as:
- fertiliser production and transport for feed crops and pasture (CO2 and N2O)
- feed manufacture and transport (CO2)
- livestock (enteric fermentation) (CH4)
- manure and urine (CH4 and N2O)
- slaughtering
- processing
- refrigeration
- transport
- cooking (CO2 and refrigerant gases)
- and non-EU soya imports (mainly from South America) which account for 75% of the UK’s oilcake imports and 24% of total feed imports.
