This is something I’ve been wanting to know, but only the guys at Soylent have the knowledge to even begin to calculate this. I suspect, however, it’ll be higher than “traditional” foods (which could mean anything). There’s many times more processing and ingredients in Soylent than many of the food items I can think of.
Are you comparing to fruits and veggies which come from sources that actually reduce carbon in the atmosphere? Because we probably don’t have to calculate anything to know that Soylent has a higher footprint than those.
Or do you compare to meats from farm animals? Which animals? Cows have a much higher carbon footprint than chickens. Cows wouldn’t be traditional food in India, but traditional in Japan. Or do you compare to a typical meal consisting of all food groups? Again, typical by whose standards?
Fuzzy math would be right, and it’d also probably be someone’s full time job for a few months; someone at Soylent who could contact all their suppliers and research manufacturing processes, byproducts, shipping routes, customer locations, etc etc etc.
