[2] The OP's OurWorldInData graph screenshot says beef emissions are 60, but the actual page says 99. Same chart. I don't understand. https://ourworldindata.org/grapher/food-emissions-supply-cha... I used 60 in the calculation above.

The chart I used does not include losses in the supply chain. The difference between both charts is further explained here: https://ourworldindata.org/faqs-environmental-impacts-food
