  • Analysis drawing on 570 studies with data covering 38,700 commercial farms, in 119 countries, representing ~90% of all food consumed.

  • 43% of the globe’s ice-and desert-free land surface is used for agriculture

    • The food production, upstream of the consumer, accounts for ~31% of global GHGs

    • There is marked variation between farms

  • Cattle raised only for meat without any dairy co-production

    • Main model in USA

    • Has the highest GHG and land use impact.

    • Beef from dairy herds is also very high

  • Dairy uses less resources than beef

    • But somewhat worse than most other animal products

  • Animal products provide 37% of protein and 18% of calories, but are responsible for 83% of global and 56-58% of food-related emissions.

  • A global dietary shift to a completely animal-free diet would reduce food-related GHGs by ~49% and farmland by ~76%.

  • Just eliminating beef (globally) would still reduce food GHGs by 33%.

  • A dietary shift away from all animal products in the US, where per capita meat consumption is thrice the world average, could reduce food emissions 61-73%.

  • Between plant proteins 

    • Uses Tofu and not whole soy beans - interesting choice

    • Tofu is the most efficient for land and GHG emissions amongst other plant proteins

    • There are other papers often list pulses as more efficient than soy, and lower relative ratings than in this paper

  • This full impact assessment on not just GHG emissions, but also land use, freshwater use, and water pollution, led to their conclusions that a vegan diet shows to be the best way to reduce an ecological footprint.

  • Excellent presentation by author Joseph Poore at the Cambridge Climate Lecture Series.
