3.6 Conclusions

  • Food systems contribute up to 30% of global GHGs.
  • Agriculture contributes the largest share of this.
  • Within agriculture, GHGs from livestock are highest; protected horticulture can also have high impacts Some methods of transport, packaging, preparation and storage also result in foods with high GHGs.
  • Our dietary patterns have a strong bearing on overall GHGs since our demand for certain types of food drives food production and associated emissions.
