Quick Links, City Lights & CBFP
Two very quick updates:
If you missed the event at the City Lights Bookstore last week, NeoFiles has put the first half of the conversation up as a podcast:
If you listen closely, you can hear me swear on the interwebs.
Woohoo! Independent confirmation!
Akifumi Ogino of the National Institute of Livestock and Grassland Science in Tsukuba, Japan has published a paper in Animal Science Journal, calculating the environmental impact of the production of Japanese beef. New Scientist summarizes the findings:
The team looked at calf production, focusing on animal management and the effects of producing and transporting feed. By combining this information with data from their earlier studies on the impact of beef fattening systems, the researchers were able to calculate the total environmental load of a portion of beef.
Their analysis showed that producing a kilogram of beef leads to the emission of greenhouse gases with a warming potential equivalent to 36.4 kilograms of carbon dioxide. It also releases fertilising compounds equivalent to 340 grams of sulphur dioxide and 59 grams of phosphate, and consumes 169 megajoules of energy.
36.4 kg of CO2e per kg of beef, at 2.2 pounds per kg and assuming a quarter-pound of beef per burger, works out to ~4kg of CO2e from beef per burger. The number I used in my estimates for the entire burger? 4.35 kg CO2e per burger. Definitely in the same ballpark.
